Hitchcock became president of the Southern California Air Pollution Foundation (APF)[3][4] in 1954, which had been formed to fight smog. Hitchcock identified automobile exhaust and backyard incinerators as the cause and advised that significant steps would be needed--comparable to wartime efforts--to fight the problem in a meaningful way.[1] In 1963, Hitchcock was appointed to the faculty at University at Buffalo, where his work papers are now archived.
