"Peter John Landin (1930 \u2013 3rd June 2009) was a British computer scientist. He was one of the first to realize that the lambda calculus\u2191 could be used to model a programming language, an insight that is essential to development of both functional programming\u2191 and denotational semantics\u2191. He was a colleague of Christopher Strachey\u2191 and an academic at Queen Mary London\u2191."@en . "Peter Landin"@en . .
