Himmler had a layman’s fascination with biological warfare. A former chicken farmer, the Reichsführer-SS had studied agriculture in school. According to Blome, it was Himmler who was the primary motivator behind the Reich’s bioweapons program. Hitler, Blome said, did not approve of biological warfare and was kept in the dark as to specific plans. Himmler’s area of greatest fascination, said Blome, was bubonic plague.
