Isamu Akasaki

1929–2021

Isamu Akasaki (1929–2021) was a Japanese physicist and Nobel laureate who pioneered the development of blue light-emitting diodes (LEDs), a breakthrough that enabled energy-efficient white lighting and transformed display technology. He spent decades at Nagoya University and Meijo University, overcoming skepticism and technical hurdles to grow high-quality gallium nitride crystals. His work, alongside Hiroshi Amano and Shuji Nakamura, earned him the 2014 Nobel Prize in Physics.
