Nakamura worked at Nichia Chemicals in Tokushima in the 1980s and 90s, where he developed a commercially viable gallium nitride-based blue LED. During the Q&A, Nakamura—who shares the Nobel prize with Isamu Akasaki and Hiroshi Amano—told reporters he believed recognition for the blue LED should also extend to Herbert Paul Maruska, a researcher at RCA who created a functional blue LED prototype in 1972.
