Hamao Umezawa

Hamao Umezawa (梅沢 浜夫, Umezawa Hamao, October 1, 1914 – December 25, 1986) was a Japanese scientist who discovered several antimicrobial agents and enzyme inhibitors.

After graduating from the Musashi Junior and Senior High School, Umezawa completed his medical degree at the University of Tokyo Graduate School of Medicine in 1937. After serving in Japanese army during World War II Umezawa did work on tuberculosis which led to his discovery, in 1956, of antibiotic kanamycin. By this stage Umezawa was heading the Institute of Microbial Chemistry in Tokyo where his main focus was antimicrobial agents manufactured through fermentation processes. Also in the mid-1950s Umezawa discovered kasugamycin, a compound useful in combating rice molds. In the early 1960s he discovered the cancer drug bleomycin.

The Hamao Umezawa Memorial Museum in Setagaya, Tokyo was named in his honour.

Awards
gollark: Besides that, long-distance power transmission incurs losses.
gollark: Factories and datacentres and stuff need power constantly.
gollark: No, we need power *constantly*, just telling people "you're using energy wrong" is not really a good solution.
gollark: There are new innovations in nuclear power which could improve efficiency, reduce cost and improve safety too, except nobody seems to be implementing them because people seem to just... not like nuclear.
gollark: Nuclear waste isn't actually a huge issue - you could fit all nuclear waste generated so far into a small swimming pool or something and it's *much* better than the effects of fossil fuel pollution - and meltdowns are rare.
