Robert Edgar Allardice FRSE (1862 – 1928) was a Scottish mathematician, specializing in geometry. Biography Allardice matriculated in 1879 at the University of Edinburgh and received there in 1882 an M.A. in mathematics. In 1883 Allardice became assistant in mathematics to Professor George Chrystal at the University of Edinburgh and remained there until 1892. In 1892 Allardice was appointed a professor to Stanford University at the start of the University's second year and immediately became the head of the mathematics department, continuing in that position until his retirement in 1927. For many years, the senior faculty in mathematics at Stanford University consisted of Allardice and Rufus Green. The Stanford mathematics department, with Allardice as head, recruited Hans Frederick Blichfeldt and George Abram Miller. On 16 January 1888 he was elected A Fellow of the Royal Society of Edinburgh. His proposers were George Chrystal, Robert McNair Ferguson, John Sturgeon Mackay, and Peter Guthrie Tait. After suffering from a lingering illness for over a year, Allardice died in 1928 from a lung infection. He never married and upon his death was survived by a sister in Glasgow.
