Edison was an early customer of Eastman’s — their inventions were mutually complementary — and cooperated with him over a long period. Baekeland sold his photographic-paper invention to him for thirty times what he’d thought reasonable. Pathé had met Eastman early in the century, and made contact again in the 1920’s to merge their firms. Barnard briefly worked with Eastman (who was adept at employing the right people); Frances Benjamin Johnston had her first camera sent to her by Eastman, a family friend, and acted as his business agent in Washington, but it is unclear what kind of contact they enjoyed.
Profession: philanthropist
Thomas Wedgwood
Josiah Wedgwood was Thomas (or Tom) Wedgwood’s father. Both Stubbs and Darwin taught him, Darwin also prescribing the opium to which he later became addicted. Priestley and Watt were friends of Wedgwood’s father’s but with whom he also maintained a correspondence. Southey wrote to Wedgwood about Davy’s nitrous oxide; Davy wrote up Wedgwood’s important photographic image-forming discoveries. Tom and his brother supported Coleridge for most of his adult life, so he could concentrate on writing: Wedgwood and Coleridge were close friends, engaging in passionate intellectual discussion and enthusiastic drug-experimentation.
