 Foot resigned her fellowship at Somerville in 1969 and began a period of freelancing in the United States, where she held Visiting Professorships at the Universities of California, at Los Angeles and Berkeley, Washington, Princeton, Stanford, and the City University of New York. In 1976, she took up a permanent position at the University of California, Los Angeles, where she remained until retiring in 1991, then returning to Oxford, where she completed her monograph Natural Goodness. Foot’s last philosophical article appeared in 2004, and she died on her ninetieth birthday, October 3, 2010. It is sometimes thought that Foot was a founding member of Oxfam, but, in fact, the first records of her involvement date from 1948, some six years after the founding of the Oxford Committee for Famine Relief. She remained involved with Oxfam throughout her life (Hursthouse 2012: 180–181).
