Dr. Richard Smalley, winner of the 1996 Nobel Prize in Chemistry for his co-discovery of buckminsterfullerenes (“buckyballs”) has died. He was only 62.
He shared the prize with Dr. Robert Curl (who was actually my physical chemistry professor at Rice University), as well as Harold Kroto of Britain.
Dr. Smalley was a pioneer of the nanotechnology field and founded the Center for Nanoscale Science and Tecnology at Rice. I heard Dr. Smalley speak several times since graduating, and he was truly a visionary. He was also a pretty fun guy, being elected Rice’s Homecoming Queen in 1996, and listing this (along with the Nobel Prize) on his curriculum vitae.
