## Bio

Isamu Akasaki was a Japanese electronics engineer who spent decades chasing a problem most thought unsolvable: a bright blue light-emitting diode. In 1989, working in semiconductor technology, he and his colleagues cracked it with gallium nitride, producing the first bright GaN p-n junction blue LED. They pushed further, refining the technology into high-brightness versions that made practical white LED lighting possible. The work earned him the 2014 Nobel Prize in Physics, shared with Hiroshi Amano and Shuji Nakamura, for inventing efficient blue LEDs that enabled the energy-saving light sources now everywhere. He died on April 1, 2021.
