Gérard Simon (1931-2009) was a French historian of science known for his distinctive approach that interlinked the cultural contexts of science and epistemology. An alumnus of the École normale supérieure, he studied under renowned philosophers Louis Althusser and Michel Foucault. His doctoral dissertation focused on Johannes Kepler, emphasizing the coexistence of astrology and astronomy in Kepler's work. Simon challenged the positivist historiography that marginalized Kepler's astrological contributions, highlighting the complexity of historical knowledge systems during the 16th and 17th centuries.
