Caption: Hugo Lieber (1868-1936), German-born US chemist and hearing aid pioneer. Lieber arrived in the USA in 1891 and founded a chemical company in New York. In 1901, he established the trade newspaper 'Light' for the gaslight industry. He also studied the newly discovered chemical element radium, and in 1909 was a founding member and treasurer of the Radium Institute of America. In 1922, he began work on hearing aids for the deaf, inventing a bone conduction receiver called the sonotone. He founded the Sonotone Corporation in 1929, marketing the new hearing device from 1932.
