December 8, 2008. The explosion flash blinded Shimomura for about thirty seconds, and he was later drenched by the "black rain" bomb fallout. He overcame great odds in the following 11 years to earn an education and achieve academic success.
Shimomura's education opportunities were starkly limited in devastated, post-war Japan. Although he later recalled having no interest in the subject,
he enrolled in the College of Pharmaceutical Sciences of Nagasaki Medical College (now
Nagasaki University School of Pharmaceutical Sciences).
The Medical College campus had been entirely destroyed by the atomic bomb blast, forcing the pharmacy school to relocate to a temporary campus near Shimomura's home. This proximity was the fortuitous reason he embarked upon the studies and career which would ultimately lead to unanticipated rewards.
Shimomura was awarded a
BS degree in pharmacy in 1951, and he stayed on as a lab assistant through 1955.
Shimomura's mentor at Nagasaki helped him find employment as an assistant to Professor
Yoshimasa Hirata at

While working for Professor Hirata, he received a
MS degree in organic chemistry in 1958 and, before leaving Japan for an appointment at Princeton University, a
Ph.D. in organic chemistry in 1960 at Nagoya University. At Nagoya, Hirata assigned Shimomura the challenging task of determining what made the crushed remains of a type of
