Albert C. BarnesBorn 2 Jan 1872; died 24 Jul 1951 at age 79.Albert Coombs Barnes was an American chemist who invented the antiseptic Argyrol (1902). This is a silver-protein compound used in aqueous solution as a topical antiseptic. Believing in the social theories of philosophers such as John Dewey, Barnes felt he could better the lives of his fellow citizens. He applied his own ideas in his own factories. He scheduled his workers on 8-hour shifts 6 hours on the production line, followed by 2 hours of lectures on esthetics and art. He became a noted art collector, whose collection is now in the Barnes Foundation galleries in Merion, outside Philadelphia. Barnes' theories of art appreciation continue to be taught at the Barnes Foundation today. Dr. Barnes died in a car crash in 1951. |
