Introduction Beyond his seminal contributions to the theory and the design of concurrent and distributed algorithms, Leslie Lamport has throughout his career worked on methods and formalisms for rigorously establishing the correctness of algorithms. Commenting on his first article about a method for proving the correctness of multi-process programs [32] on the website providing access to his collected writings [47], Lamport recalls that this interest originated in his submitting a flawed mutual-exclusion algorithm in the early 1970s. As a trained mathematician, Lamport is perfectly familiar with mathematical set theory, the standard formal foundation of classical mathematics. His career in industrial research environments and the fact that his main interest has been in algorithms, not formalisms, has certainly contributed to his designing reasoning methods that combine pragmatism and mathematical elegance.
