Vintage 2x3 sepia photograph signed in fountain pen ink by Adolf Butenandt. Excellent condition. (1903-1995) Adolf Friedrich Johann Butenandt was a German biochemist. He was awarded the Nobel Prize in Chemistry in 1939 for his "work on sex hormones." He initially rejected the award in accordance with government policy, but accepted it in 1949 after World War II. He was President of the Max Planck Society from 1960 to 1972. He was also the first, in 1959, to discover the structure of the sex pheromone of silkworms, which he named bombykol.This lot came from the Jim Wiggins collection we purchased in July 2022. Jim Wiggins accumulated the most unique and valuable autograph collection over a period of 70-plus years. He obtained his collection either in person or by writing to persons of fame and notoriety. Comes with a full Letter of Authenticity from Todd Mueller Authentics.
