Ludwig Prandtl (4 February 1875 – 15 August 1953) was a German physicist. He was a pioneer of aerodynamics, and developed the mathematical basis for the fundamental principles of subsonic aerodynamics in the 1920s. His studies identified the boundary layer, thin-airfoils, and lifting-line theories. The Prandtl number was named after him.
Early years
Prandtl was born in Freising, near Munich, in 1875. His mother suffered from a lengthy illness and, as a result, Ludwig spent more time with his father, a professor of engineering. His father also encouraged him to observe nature and think about his observations.
He entered the Technische Hochschule Munich in 1894 and graduated with a Ph.

These texts provide the meanings of planets, or combination of planets, in signs and in houses, as well as the interpretations of planetary dominants in line with modern Western astrology rules. Moreover, since Astrotheme is not a polemic website, no negative aspect which may damage the good reputation of a celebrity is posted here, unlike in the comprehensive astrological portrait.
Here are some character traits from Ludwig Prandtl's birth chart. This description is far from being comprehensive but it can shed light on his/her personality, which is still interesting for professional astrologers or astrology lovers.
In a matter of minutes, you can get at your email address your astrological portrait (approximately 32 pages), a much more comprehensive report than this portrait of Ludwig Prandtl.
When interpreting a natal chart, the best method is to start gradually from general features to specific ones. Thus, there is usually a plan to be followed, from the overall analysis of the chart and its structure, to the description of its different character traits.
In the first part, an overall analysis of the chart enables us to figure out the personality's main features and to emphasize several points that are confirmed or not in the detailed analysis: in any case, those general traits are taken into account. Human personality is an infinitely intricate entity and describing it is a complex task. Claiming to rapidly summarize it is illusory, although it does not mean that it is an impossible challenge. It is essential to read a natal chart several times in order to absorb all its different meanings and to grasp all this complexity. But the exercise is worthwhile.
In brief, a natal chart is composed of ten planets: two luminaries, the Sun and the Moon, three fast-moving or individual planets, Mercury, Venus and Mars, two slow-moving planets, Jupiter and Saturn, and three very slow-moving planets, Uranus, Neptune and Pluto. Additional secondary elements are: the Lunar Nodes, the Dark Moon or Lilith, Chiron and other minor objects. They are all posited on the Zodiac wheel consisting of twelve signs, from Aries to Pisces, and divided into twelve astrological houses.
The first step is to evaluate the importance of each planet. This is what we call identifying the dominant planets. This process obeys rules that depend on the astrologer's sensitivity and experience but it also has precise and steady bases: thus, we can take into account the parameters of a planet's activity (the number of active aspects a planet forms, the importance of each aspect according to its nature and its exactness), angularity parameters; (proximity to the four angles, Ascendant, Midheaven, Descendant and Imum Coeli or Nadir, all of them being evaluated numerically, according to the kind of angle and the planet-angle distance) and quality parameters (rulership, exaltation, exile and fall). Finally, other criteria such as the rulership of the Ascendant and the Midheaven etc. are important.
These different criteria allow a planet to be highlighted and lead to useful conclusions when interpreting the chart.
The overall chart analysis begins with the observation of three sorts of planetary distributions in the chart: Eastern or Western hemisphere, Northern or Southern hemisphere, and quadrants (North-eastern, North-western, South-eastern and South-western). These three distributions give a general tone in terms of introversion and extraversion, willpower, sociability, and behavioural predispositions.
Then, there are three additional distributions: elements (called triplicity since there are three groups of signs for each one) - Fire, Air, Earth and Water - corresponding to a character typology, modality (or quadruplicity with four groups of signs for each one) - Cardinal, Fixed and Mutable - and polarity (Yin and Yang).
There are three types of dominants: dominant planets, dominant signs and dominant houses. The novice thinks astrology means only "to be Aries" or sometimes, for example, "to be Aries Ascendant Virgo". It is actually far more complex. Although the Sun and the Ascendant alone may reveal a large part of the character - approximately a third or a half of your psychological signature, a person is neither "just the Sun" (called the sign) nor just "the first house" (the Ascendant). Thus, a particular planet's influence may be significantly increased; a particular sign or house may contain a group of planets that will bring nuances and sometimes weaken the role of the Ascendant, of the Sun sign etc.
Lastly, there are two other criteria: accentuations (angular, succedent and cadent) which are a classification of astrological houses and types of decanates that are occupied (each sign is divided into three decanates of ten degrees each). They provide some additional informations.
These general character traits must not be taken literally; they are, somehow, preparing for the chart reading. They allow to understand the second part of the analysis, which is more detailed and precise. It focuses on every area of the personality and provides a synthesis of all the above-mentioned parameters according to sound hierarchical rules.
Each quadrant is a combination of the four hemispheres of your birth chart and relates to a character typology. The Southern hemisphere – the top of your chart, around the Midheaven – is associated with extraversion, action, and public life, whereas the Northern hemisphere prompts to introversion, reflexion, and private life. The Eastern hemisphere – the left part, around the Ascendant – is linked to your ego and your willpower, whereas the Western hemisphere indicates how other people influence you, and how flexible you are when you make a decision.
Ludwig Prandtl, the nocturnal North-western quadrant, consisting of the 4th, 5th and 6th houses, prevails in your chart: this sector favours creativity, conception and some sort of specialization or training, with helpfulness and relations as strong components. You need others' cooperation in order to work properly, although you are not very expansive: creating, innovating and thinking are what matter most to you because this self-expression enriches you and totally satisfies you.
Ludwig Prandtl, here are the graphs of your Elements and Modes, based on planets' position and angles in the twelve signs:
Like the majority of Earth signs, Ludwig Prandtl, you are efficient, concrete and not too emotional. What matters to you is what you see: you judge the tree by its fruits. Your ideas keep changing, words disappear, but actions and their consequences are visible and remain. Express your sensitivity, even if it means revealing your vulnerability. Emotions, energy and communication must not be neglected; concrete action is meaningless if it is not justified by your heart, your intellect or your enthusiasm.
Cheers for communication and mobility, Ludwig Prandtl! The predominance of Air signs in your chart favours and amplifies your taste for relations and for all kinds of short trips, whether real (travels) or symbolic (new ideas, mind speculations). You gain in flexibility and adaptability what you lose in self-assertion or in pragmatism.
The twelve zodiacal signs are split up into three groups or modes, called quadruplicities, a learned word meaning only that these three groups include four signs. The Cardinal, Fixed and Mutable modes are more or less represented in your natal chart, depending on planets' positions and importance, and on angles in the twelve signs.
The Fixed mode corresponds to a majority of elements in your chart, Ludwig Prandtl, and represents the desire for security and durability: you are able to concretely appreciate a situation and its stability. You definitely prefer to play the role of a loyal, obstinate and hard-working person, rather than to try new and risky experiences - beware, however, not to confuse obstinacy with intransigence. You structure, cement, and strengthen everything you find on your way: it is your nature, although you are not especially interested in swiftness: slow and steady...
Houses are split up into three groups: angular, succedent and cadent.
The first ones are the most important ones, the most "noticeable" and energetic houses. They are the 1st, 4th, 7th and 10th houses. Their cuspides correspond to four famous angles: Ascendant for the 1st house, Imum Coeli for the 4th house, Descendant, opposite the Ascendant, for the 7th house and Midheaven for the 10th house, opposite the Imum Coeli.
Planets are evaluated according to a whole set of criteria that includes comprehensive Western astrology rules. At their turn, planets emphasize specific types of houses, signs, repartitions etc., as previously explained.
Cadent houses, namely the 3rd, 6th, 9th and 12th houses, are very emphasized in your chart, Ludwig Prandtl. They indicate important potential for communication, adaptability and flexibility. These houses are symbolically linked to the mind and intellect. The relative weakness implied by these characteristics indicates your tendency to hesitate or to be indecisive, but also your remarkable ability to start off again, which is a nice quality, finally: you can easily get yourself out of a tight spot thanks to your mobility and casualness, in the best sense of the term. This group of houses corresponds to evolutionary characteristics of your personality. However, they are only indications and you must include them in the rest of your chart in order to see whether they are validated or not!
N.B.: this dominant is a minor one.
The issue of dominant planets has existed since the mists of time in astrology: how nice it would be if a person could be described with a few words and one or several planets that would represent their character, without having to analyse such elements as rulerships, angularities, houses, etc!
The ten planets - the Sun throughout Pluto - are a bit like ten characters in a role-play, each one has its own personality, its own way of acting, its own strengths and weaknesses. They actually represent a classification into ten distinct personalities, and astrologers have always tried to associate one or several dominant planets to a natal chart as well as dominant signs and houses.
Indeed, it is quite the same situation with signs and houses. If planets symbolize characters, signs represent hues - the mental, emotional and physical structures of an individual. The sign in which a planet is posited is like a character whose features are modified according to the place where he lives. In a chart, there are usually one, two or three highlighted signs that allow to rapidly describe its owner.
Regarding astrological houses, the principle is even simpler: the twelve houses correspond to twelve fields of life, and planets tenanting any given house increase that house's importance and highlight all relevant life departments: it may be marriage, work, friendship etc.
In your natal chart, Ludwig Prandtl, the ten main planets are distributed as follows:
The three most important planets in your chart are Mercury, Mars and Venus.
With Mercury among your dominant planets, you are certainly cerebral, nervous, swift, curious, quick-witted, and you love to communicate. Your psychological pattern is intellectual, all the more so since Mercury is important, with its whole set of assets but also of weaknesses, obviously.
Your sensitivity, emotions, and heart's impulses give precedence to thinking, which can lead people to believe that you are a playful and witty but heartless person, intellectualizing situations and juggling with words and numbers whilst ignoring human aspects of things. Of course, it is said that cats always land on their feet - this is your Mercurian strength and your trump card!
Your weakness lies in your nervousness, and you may miss your goal because of your "over-intellectualization" that may be detrimental to other kind of energies such as instinct, spontaneity, heart, sensitivity, etc.
Mars is one of your dominant planets and provides you with its efficient energy and enthusiasm: with a powerful Mars in your chart, action - but also will and ability to undertake - is not an empty word for you. You are active, dynamic, willing to fight, courageous, and you are never afraid to move mountains, even though risks are part of the adventures that you start with determination.
However, your patience is not always up to your boldness and a kind of feverishness, or even anger, can tarnish the quality of your achievements. That would be a pity since the Marsian is a champion in matters of efficiency! Mars symbolizes display of action, conquering spirit that favours discipline and order - beware of not being fussy - and lies at the frontier between action and brutality, between conquest and potential aggressiveness.
With Venus among your dominant planets, one of your first reflexes is... to please! Your look, your charm, and your seduction are omnipresent elements in your behaviour.
Your approach to things is connected to your heart, and for you, no real communication can flow if your interlocutors exude no sympathy or warmth. Cold and logical reasoning, clear thoughts and good sense are not important to you: if there is no affective bond with your environment, no connection can be established with the Venusian that you are, and nothing happens.
You have a strong artistic side, and you never neglect subjective but clear concepts such as pleasure, beauty, and also sensuality. However, sometimes to the detriment of efficiency, durability, logic, and... detachment.
In your natal chart, the three most important signs - according to criteria mentioned above - are in decreasing order of strength Aquarius, Scorpio and Virgo. In general, these signs are important because your Ascendant or your Sun is located there. But this is not always the case: there may be a cluster of planets, or a planet may be near an angle other than the Midheaven or Ascendant. It may also be because two or three planets are considered to be very active because they form numerous aspects from these signs.
Thus, you display some of the three signs' characteristics, a bit like a superposition of features on the rest of your chart, and it is all the more so if the sign is emphasized.
Aquarius is one of the most important signs in your natal chart: it endows your personality - at least one of its facets - with originality, to the point of eccentricity, in spite of a sometimes distant and humane side. Likeable and impassive at the same time, you are a paradoxical man, very hard to define because the two planets Uranus and Saturn blend their qualities to create the so complicated and endearing sign that inspires your character. Saturn's seriousness and impassivity is added to Uranus' rebellion, talent, individualism, charisma, extravagance, and unpredictability! One of your main characteristics is that you never open up on a personal basis, but you tend to do so easily in public. You are actually quite strange. Sexy and charming in public, despite your nice and sociable character, you could frustrate many of your admirers in private because of your impossibility to show deep and warm affection, emotions, tears... But appearance and reality are two different things anyway - you are a kind of a genius, or you have at least a tremendous charm with this sign. You have many friends and an active social life. If you are detached in your love life - only in this aspect, since the rest of chart will confirm it or not - this is no big deal!
With Scorpio as a dominant sign, you are a strong and astute person, complicated and passionate, sometimes destructive and intolerant, but strong-willed, tough and daring, sometimes bordering on aggressive. So many qualities and dangers combined in one person! Obviously, this often results in a natural selection of people around you: those who stand up to you or admire you and those who can't bear you anymore! But that is precisely what you want. You are what you are and you are not going to transform yourself just to please. You are too proud and you never dread confrontations, although your way of fighting is secret, like your nature that, mysteriously enough, you are so reluctant to reveal even to your close friends who will never understand you. That said... what a hellish charm you have!
Virgo, associated with perfectionism, numbers and reason, is among your dominant signs: you inherit its sense of responsibility and tidiness, a clear mind, an unfailing logic, as well as a need to be useful and to fulfil your task to the best of your abilities. Obviously, people may think that you are too modest or reserved, suspicious or pessimistic because of your exceedingly critical mind, but aren't logic and wisdom great qualities? Of course, they are. Moreover, you keep your feet on the ground, you never behave irrationally and you are helpful and hardworking - what more can you ask for?!
The 6th, 3rd and 9th houses are the most prominent ones in your birth chart. From the analysis of the most tenanted houses, the astrologer identifies your most significant fields or spheres of activity. They deal with what you are experiencing - or what you will be brought to experience one day - or they deal with your inner motivations.
Your 6th house is quite emphasized and indicates interest in work and daily occupations that take up a lot of your time: in analogy with Virgo, this house inclines towards perfectionism and training; somehow, you may be fulfilled through the process of being useful and investing your energy in your work. An environment appealing to you may be involved - your colleagues, for example - or a passion for one of these daily occupations. Medical positions or pets may play a role in your life; or ancillary love affairs too... These are a few possibilities indicated by an important 6th house.
As the 3rd house is one of the most important houses in your chart, communication plays a major role in your life or in your deep motivations: frequent short trips, open-mindedness - which may offset a lack of mutable signs for instance - listening, discussion, interest in learning, knowledge accumulation or long-term studies, etc., are all areas that greatly appeal to you and are part of your daily life.
Your 9th house being one of your most tenanted house, or at least emphasized, travels and faraway places play a major role for you: travels may take place in a symbolic sense, namely mind speculations or conceptions about political matters, philosophy, religion or spirituality, or in the literal sense, such as real long distance travels by plane. It may also be that you spend a part of your life far from home, etc. You are driven by some kind of rebelliousness, which urges you to explore the Unknown; it may also be the call of the adventure. Besides, if the rest of your chart concurs, you may be considered as a real draught, often up hill and down dale, constantly on the lookout for exciting discoveries and new, enchanting horizons.
After this paragraph about dominant planets, of Ludwig Prandtl, here are the character traits that you must read more carefully than the previous texts since they are very specific: the texts about dominant planets only give background information about the personality and remain quite general: they emphasize or, on the contrary, mitigate different particularities or facets of a personality. A human being is a complex whole and only bodies of texts can attempt to successfully figure out all the finer points.
Votre sensibilité est en retrait Ludwig Prandtl : plus que tout autre, vous avez tendance à vous enfermer dans votre tour d'ivoire, quelque part conscient d'une forme de supériorité souvent réelle mais parfois surfaite. Vos humeurs ne sont pas visibles car vous les disciplinez et les contrôlez complètement de main de maître. Difficile pour quiconque de savoir si vous êtes heureux ou contrarié, rien ou presque ne se voit. Vous fuyez les situations où vous devez dévoiler vos émotions tant vous êtes peu démonstratif. Attention, il ne s'agit pas ici de votre comportement sur le plan amoureux qui peut être tout à fait différent, mais du mode sensible quotidien par lequel vous vous exprimez. La foule vous fait peur et vous vous sentez bien dans le calme et même la solitude. Bien armé pour rester équilibré en toutes circonstances, vous gagnerez petit à petit à "vous lâcher" et donner un peu plus de vous car vous en valez la peine ; cela est plus facile lorsqu'un projet ou une ambition sont là pour justifier une extériorisation de ce que vous ressentez. Les effusions gratuites d'émotions, particulièrement en groupe, vous sont étrangères ou refoulées car vous avez une certaine peur de vous livrer comme si vous étiez sur la défensive, sans aucune raison la plupart du temps.
C'est dans le cadre récréatif, les loisirs et les fêtes, les aventures amoureuses, les vacances etc. que vous exprimez le mieux vos émotions, Ludwig Prandtl. Vous aimez la compagnie des enfants, votre popularité est souvent bonne et vous en profitez pour multiplier les rencontres afin de constater... (excerpt)
Vous êtes Ludwig Prandtl un "libre-penseur" qui appréhendez les problèmes avec un esprit rapide et efficace. Liberté, progrès et originalité sont vos moteurs. Résolument tourné vers l'avenir, vous faites preuve d'ingéniosité et d'inventivité pour réformer ce qui n'a plus lieu d'être et innover sans cesse : psychologie, informatique, nouvelles technologies... n'ont presque plus de secret pour vous. Doté de qualités humaines et idéalistes évidentes, vous êtes un interlocuteur fort sympathique et très intéressant, même si l'on peut parfois vous reprocher votre côté rebelle et révolutionnaire. En effet, un esprit de contradiction assez développé semble vous animer : vous pensez rarement comme tout le monde et au risque de vous montrer obstiné, intransigeant et désagréable, vous le dites ! Au lieu de provoquer de soudaines ruptures amicales apprenez plutôt à persévérer dans vos efforts et laissez s'exprimer davantage votre potentiel créatif quand vous ressentirez une trop grande tension nerveuse.
Donner le maximum de votre puissance intellectuelle, c'est pour vous naturellement dans le travail que vous pouvez le faire, Ludwig Prandtl. A quoi bon se décarcasser la cervelle si ce n'est pour être utile professionnellement, grimper les échelons, être reconnu par ses collègues de travail et se... (excerpt)
Dans votre thème, le Soleil est en Verseau, Vénus en Sagittaire. Cette configuration planétaire met en présence deux types d'affectivité complémentaires à bien des égards. En commun, le Soleil Verseau et la Vénus Sagittaire ont un penchant prononcé pour les découvertes, l'inédit, les amours sans limites... Le Soleil Verseau est en devenir, en perpétuelle recherche. L'amour ne peut qu'être plus intense demain, chaque jour étant porteur d'un essor affectif. Aussi résolument tournée vers l'avenir, la Vénus Sagittaire se nourrit des sollicitations extérieures : le désir naît des multiples tentations qu'un monde toujours à explorer ne manque pas de susciter. Le risque est bien sûr une certaine instabilité : comment se contenter d'un amour présent, souvent dénué de l'inédit sans lequel on s'ennuie fatalement. Insatisfaite l'affectivité ? Peut-être. Mais pas nécessairement... L'équilibre d'une telle configuration, fragile mais exaltant, réside dans une exceptionnelle faculté de renouveler la relation, de donner un élan neuf aux élans du coeur et de s'abstraire ainsi des vicissitudes de l'existence affective. Eviter de laisser s'enliser le coeur dans les sables mouvants d'une vie commune durable, tel est le défi de ce duo planétaire. Au moins ainsi est-on sûr de ne jamais s'ennuyer en votre compagnie, tant la séduction se doit d'être renouvelée, encore et toujours.
Affectivement, vous êtes Ludwig Prandtl, ouvert, franc et spontané et vous vous liez facilement tant votre enthousiasme peut s'exprimer avec jovialité, sans détours et avec un respect des valeurs morales bien établies. Dans certains cas vous pouvez être en opposition avec votre milieu d'origine ou votre famille en raison de votre goût pour la liberté, le dépaysement ou toute forme d'indépendance et d'émancipation. Vos sentiments sont ardents et vous vous emballez assez rapidement mais par contre, cette facilité à vous lier vous prédispose en conséquence à une certaine instabilité ; en d'autres mots, la fidélité n'est pas votre priorité essentielle tant que vous n'avez pas encore rencontré l'âme soeur. Les conditions idéales pour vivre au mieux vos sentiments amoureux sont de vivre en couple avec une certaine mobilité, faire des voyages, profiter du grand air, ressentir à l'intérieur de votre relation amoureuse cette liberté et cette indépendance dont vous avez absolument besoin depuis votre enfance et à ce prix, l'harmonie et la fidélité seront au rendez-vous.
Ludwig Prandtl, votre vie sentimentale a besoin pour s'épanouir d'un socle familial solide et sécurisant à partir duquel vous pouvez enfin regarder à l'extérieur et donner libre cours à vos émois amoureux : que vous ayez eu une enfance pendant laquelle vous n'avez manqué d'aucune affection et...

The ruler of the Ascendant, also referred to as the chart ruler, brings a few interesting nuances to the meanings provided by the Sun and the Ascendant. The sign in which the ruler of the Ascendant is posited fine-tunes the style of personality described by the Sun and the Ascendant. It may strengthen it if the sign is identical to either of them.
The ruler of your Ascendant is in the same sign as your Sun. This specific feature means that the Sun's characteristics in sign previously delineated are strengthened.
Vous êtes un perfectionniste, Ludwig Prandtl, quelqu'un dont le souci permanent demeure de s'améliorer en toutes choses, accumuler des connaissances, devenir utile au meilleur de ses performances et de ses compétences. Le travail pour vous est un domaine important et en général contrairement à d'autres, vous... (excerpt)
Votre volonté de fer fait partie de vos atouts, Ludwig Prandtl. Elle est servie par une ingéniosité et une habileté qui peuvent faire de vous une personnalité puissante et crainte. Vous avez le flair pour trouver les faiblesses de ceux qui vous approchent et vous pouvez facilement les blesser par votre penchant naturel et inné à sonder ou tester leur force. Vous êtes extrêmement têtu et vous ne lâchez pratiquement jamais prise si vous êtes convaincu que vous avez raison. Sexuellement, vous êtes puissant et passionné. Dominateur et secret, vous êtes une personnalité magnétique avec qui il vaut mieux éviter tout conflit car vous pouvez être vraiment très agressif et rancunier et dans certains cas rares faire preuve de sadisme. Vous êtes finalement une personnalité aussi secrète qu'entière et dominatrice sur le plan de l'action et de la sexualité.
Votre entourage est rapidement conscient de votre vivacité et de votre esprit… polémique et parfois rapide, Ludwig Prandtl. En effet, votre énergie est efficacement mise en œuvre dans la communication, les écrits, les joutes verbales, les discours etc. mais aussi d'une façon plus concrète dans votre vie... (excerpt)
