Figures 6a and 6b: Physicians and painters
In his first publication (1955), MG showed how diurnal Mars for 576 members of the Paris Academy of Medicine and diurnal Saturn for 906 eminent painters gave fourfold patterns, that were out of phase. The painters gave minima for Mars in the Key Sectors whereas physicians gave maxima for Saturn (L'Influence des Astres, pp.113, 183).
Character-Trait Data volumes The Gauquelins published four volumes of character-traits, with lists of eminent persons for whom the trait featured in their biographies. These traits feature in the four sections 9-12. The volumes are quite difficult to get hold of. Here is the data-section from the volume on Jupiter and Actors (PDF file).
MG's Eureka Moment
In 1983 MG described how:
Then the breakthrough came when a close friend, who was very interested in my projects of astrological analysis, showed me a work called the 'Index des Membres, Correspondents et Associés de l'Académie de Médicine. Having (painfully) worked out by hand the position of the planets at the hour of birth of each doctor, I made a statistical compilation of my findings.
Suddenly, I was presented with an extraordinary fact. My doctors were not born under the same skies as the common run of humanity. They had chosen to come into the world much more often during roughly the two hours following the rise and culmination of the planets, Mars and Saturn. Moreover, they tended to 'avoid' being born following the rise and culmination of the planet Jupiter.
~MG, The Truth about Astrology, 1983, pp.20-21.
The date for this insight was supplied by Françoise Gauquelin:
'His [MG's] first significant results, after years of disappointing outcomes with various astrological theories, showed up in 1951 with 576 French Academicians of Medicine.'
