In Part Four of our ongoing genealogy of queer computing (Part One, Part Two, Part Three), we introduce a second generation of queer scholars who made important contributions to the field of computer science, and from whom we may trace a direct connection back to those familiar foundational figures.
On June 20, 2009 at 4pm at The Hampstead Quaker Meeting House in London, a memorial service was held for Professor Peter Landin. In attendance were his family and the friends whose lives he had touched over the last 78 years. It was a collision of worlds, a sudden mixing of two communities that Landin had kept separate his entire life. Landin's friend and colleague Olivier Danvy likened the event to the memorial for the French mathematical logician Jean van Heijenoort, author of From Frege to Gödel (1967).[1] In the early part of his life, van Heijenoort had been the personal secretary and bodyguard of Leon Trotsky, the famous Russian Marxist revolutionary and theorist, and the founder and first leader of the Red Army.

Peter Landin had also led something of a double life. He was a foundational figure in computer science, and a pioneer of programming language design based on mathematical logic and the Lambda calculus. He was ...
