Isamu Akasaki (赤崎 勇, Akasaki Isamu, January 30, 1929 – April 1, 2021) was a Japanese engineer and physicist. He was best known for inventing the bright gallium nitride (GaN) p-n junction blue LED in 1989.[1][2][3][4]

Akasaki was awarded the Kyoto Prize in Advanced Technology in 2009.[5] He was also awarded the 2014 Nobel prize in Physics with Hiroshi Amano and Shuji Nakamura[6] "for the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources".

Akasaki died on April 1, 2021 at his home in Nagoya, Japan from pneumonia, aged 92.[7]
