...award in Chemistry (deferred from last year) went to Professor Richard Kuhn of Berlin, who isolated Vitamin B 2 (also called lactoflavin or riboflavin). The 1939 award in Chemistry was divided between Professor Adolf Butenandt, also of Berlin, and Professor Leopold Ruzicka of Zurich. Butenandt isolated the male sex hormone, androsterone, and Ruzicka first synthesized it from the fat of sheep's wool...
...virile. But the real advance in man's age-old search for virility began only: 1) when Dr. Adolf Butenandt of Germany, after treating 62,500 gallons of urine, succeeded in crystallizing one two-thousandths of an ounce of male sex hormone called "androsterone"; 2) when Leopold Ruzicka of Switzerland manufactured a similar substance "testosterone" from the fat of sheep's wool (TIME, Sept...
...Until recently the two known male hormones were androsterone, first obtained by Butenandt of Germany, and a much more powerful one called testosterone, isolated by Laqueur of The Netherlands. In 1934-35 both of these were synthesized by Ruzicka of Switzerland. Last week Dr. Russell E. Marker and his associates of Pennsylvania State College announced isolation and synthesis of a third male hormone, secreted in the bodies of women...
...symposium of modern times. The explanation of their respective countries and peoples given by Prof. Anesaki of Japan and Dr. HuShin of China; the glimpses into industrialism of the future disclosed by Dr. Bergius; and the startling possibilities of the work done in biological chemistry by such men as Ruzicka of Switzerland; are the parts of the Tercentenary to be permanently remembered. The flattery of Boston newspapers is pleasant, the exercises in the new Tercentenary theater cannot fail to be impressive, nor the fireworks on the river exciting, but all these merely reflect an inner pride. They seem small beside...
...produce one ounce of natural testosterone would require the castration of some 1,000,000 sturdy men. German and Swiss chemical laboratories are already prepared, said Dr. Ruzicka last week, to manufacture from sheep's wool all the testosterone the world needs to cure homosexuals, revitalize...
