Born in Kyoto, Japan, on August 27, 1928, Osamu Shimomura graduated from Nagasaki College of Pharmacy in 1951 and worked as a research student in Organic Chemistry at the laboratory of Professor Hirata at Nagoya University from 1955 to 1958. He obtained his Ph.D. in organic chemistry from Nagoya University in 1960. He was a research biochemist at Princeton University from 1965 to 1981, and is a professor emeritus at Boston University Medical School. Dr. Shimomura, prior to his retirement, was an MBL senior scientist from 1982-2001. He first noticed a green fluorescing molecule in the jellyfish Aequorea in 1961. He patiently extracted the molecule from 10,000 specimens, purified it, and identified as a protein. Dr. Shimomura is the 57th scientist affiliated with the MBL since its founding in 1888 to receive the Nobel Prize.
