Samuel Ruben

Samuel Ruben (14 July 1900 - 16 July 1988) was an American inventor who made lasting contributions to electrochemistry and solid-state technology, including the founding of Duracell.
==Early life==
Samuel Ruben got his start in electronics when he became a licensed ham radio operator and built radios with spare parts. Samuel Ruben met Professor Bergen Davis of Columbia University who tutored him and allowed him to sit in on some Columbia classes. He also taught at Harvard as a lecturer in chemistry.
While he had no college degree, withdrawing from college after a short time due to stress, Ruben received several honorary degrees. He was awarded an honorary Doctor of Science degree from Columbia University in the Department of Chemical Engineering and Applied Science where he was a Senior Staff Associate.
