1977 Unused vintage Progress in Electronics postage stamps. Face value is 11¢ per stamp.
De Forest was descended from Jesse de Forest, who’d led a group of Walloon Huguenots from Europe in the 1600s. His father was a minister who hoped that his son would become a pastor, but he went to Yale’s Sheffield Scientific School instead.
De Forest’s most famous invention was the Audion vacuum tube, “a device for amplifying feeble electric currents.” His invention resulted in the first radio broadcast in 1907, earning de Forest the name “Father of the Radio.”
