Robin Gandy

Robin Gandy was born in the village of Rotherfield Peppard, Oxfordshire, England.[4] He was the son of Thomas Hall Gandy (1876–1948) and Ida Caroline née Hony (1885–1977) and great-great-grandson of the architect and artist Joseph Gandy (1771–1843).

Educated at Abbotsholme School, Gandy took two years of the Mathematical Tripos, at King's College, Cambridge, before enlisting for military service in 1940. During World War II he worked on radio intercept equipment at Hanslope Park, where Alan Turing was working on a speech encipherment project, and he became one of Turing's lifelong friends and associates. In 1946, he completed Part III of the Mathematical Tripos, then began studying for a PhD under Turing's supervision. He completed his thesis, On axiomatic systems in mathematics and theories in Physics, in 1952.[1] He was a member of the Cambridge Apostles.

Gandy held positions at the University of Leicester, the University of Leeds, and the University of Manchester. Gandy was a visiting associate professor at Stanford University from 1966 to 1967, and held a similar position at University of California, Los Angeles in 1968. In 1969, he moved to Wolfson College, Oxford, where he became Reader in Mathematical Logic.

Robin Gandy is known for his work in recursion theory. His contributions include the Spector–Gandy theorem, the Gandy Stage Comparison theorem, and the Gandy Selection Theorem. He also made a significant contribution to the understanding of the Church—Turing thesis, and his generalisation of the Turing machine is called a Gandy machine.[8]

Gandy died in Oxford, England.[4][9]

The Robin Gandy Buildings, a pair of accommodation blocks at Wolfson College, Oxford, are named after Gandy.[10][11] A one-day centenary Gandy Colloquium was held on 22 February 2020 at the College in Gandy's honour, including contributions by some of his students.[12][13] The speakers were Marianna Antonutti Marfori (Munich), Andrew Hodges (Oxford), Martin Hyland (Cambridge), Jeff Paris (Manchester), Göran Sundholm (Leiden), Christine Tasson (Paris), and Philip Welch (Bristol).
