Joseph Lewis Henderson (August 31, 1903 – November 17, 2007) was an American physician and a Jungian psychologist. Called by some the “Dean of American analytical psychologists", he was a co-founder of the C.G. Jung Institute in San Francisco and continued in private practice into his 102nd year. When he died, at the age of 104, he was "the last of the first generation of Jungian analysts who had their primary analysis with Jung." Source: Wikipedia (en)
