Perhaps somewhat unsurprising, the aeromedical scene in Germany was predominantly male. While there were more than a few women with medical degrees, reseachers in aviation medicine usually had an aviation background themselves (i.e. many of them held pilot licenses) and the aviator scene was dominated by male pilots (with a few notable exceptions, such as Hanna Reitsch).
Furthermore, during the war most male medical students got drafted into the armed forces (and only male students could serve as medical staff, with women only used as nurses in military hospitals). This resulted in Luftwaffe medical officers working in research facilities where they would carry out research projects for the Luftwaffe, often in conjunction with dissertation work.
NB the “N/A” in the above chart refers to the number of actors that haven't been identified yet and where no gender can be derived from the forename (usually because the forename is abbreviated).
