DOROTHY JOSEPHINE DEL BOURGO KELLOGG STEIN
Dorothy Josephine Del Bourgo Kellogg Stein, as her many names might well suggest, led more than one life, and more than one of these lives came well within arm's length of some major scientific development of the twentieth century. She led a peripatetic life: Dorothy grew up in New York City and Venezuela, graduated with a degree in physics from Cornell, studied physics in Copenhagen. In Washington DC, she learned to program computers on the ORDVAC, the world's first computer with its own compiling language (i.e. the first computer that could actually talk to people). She took up child psychology as a behaviorist but continued it as a Piagetian cognitivist in Minnesota and Hawaii. Moving to Oahu with her husband Burton Stein, she helped to establish the women's studies department at the University of Hawaii with Joan Abramson and Doris Ladd. Moving to London four decades ago, she wrote a controversial biography of Ada Lovelace (Ada, A life and a legacy) and demography (People who count). She died on March 16, 2019, just two weeks shy of her 88th birthday. She is survived and will be much missed by her sister Constance and her two sons, Kenneth and David Kellogg. Private services will be held in London.
Our deepest condolences to the family and friends of the deceased
