Beatrice Worsley

Beatrice Helen Worsley (October 18, 1921 to May 8, 1972), known as Trixie Worsley, was a Canadian computer scientist, the first woman in the country to work in that profession. She received her PhD from the University of Cambridge, advised by Douglas Hartree with additional guidance from Alan Turing, one of the earliest PhDs granted in what would today be called computer science, earned in parallel with David Wheeler's own PhD studies at Cambridge under Maurice Wilkes. She wrote the first program to run on EDSAC and co-wrote the first compiler for the University of Toronto's Ferranti Mark 1, then taught computing and engineering at Queen's University and the University of Toronto for over twenty years before her death at age fifty.
