The Original Blue LED
Trying to light up the original blue LED.
Days after the Nobel Prize for physics was awarded to three Japanese-born scientists for their work with LED lights, CHF’s Benjamin Gross and retired physicist Jonathan Allen visited The College of New Jersey’s Sarnoff Collection, a small electronics museum where Ben serves as curator and Jonathan volunteers. Their target: what they described as the original blue LED, made in 1972 by an RCA researcher named Herb Maruska. With Herb on speakerphone (hooked up to one of the collection's antique speakers, of course), Ben and Jonathan set out to light up the old contraption.
