A new exhibition at Prague’s Academy of Sciences marks the 100th
anniversary of the birth of Otto Wichterle, the great Czech chemist who
invented modern soft contact lenses in the mid 1950s. While a close
collaborator later moved to the West, Wichterle stayed in Czechoslovakia,
despite being persecuted by the Communists. He never made a cent from his
invention, as the Czechoslovak Academy of Sciences had sold his patent to a
U.S. firm. However, he didn’t mind not profiting personally, says
Professor František Rypáček, who knew him.
