Leslie Lamport is a computer scientist and mathematician. He received the 2013 Turing Award for his fundamental contributions to the theory and practice of distributed and concurrent systems.
Leslie B. Lamport was born on February 7, 1941, in New York City, into a Jewish family. His father, Benjamin Lamport, was an immigrant from Volkovisk in the Russian Empire, now Vawkavysk, Belarus. His mother, Hannah Lamport (née Lasser), hailed from the Austro-Hungarian Empire, now southeastern Poland. Lamport graduated from the Bronx High School of Science and went on to earn a B.S. in Mathematics from the Massachusetts Institute of Technology (MIT) in 1960. He later received both an M.A. (1963) and a Ph.D. (1972) in Mathematics from Brandeis University. His doctoral dissertation was titled "The analytic Cauchy problem with singular data."
Leslie Lamport's professional career began at Massachusetts Computer Associates, where he worked as a computer scientist from 1970 to 1977. He then joined SRI International (formerly Stanford Research Institute), serving from 1977 to 1985. From 1985 to 2001, Lamport was with Digital Equipment Corporation and Compaq. In 2001, he joined Microsoft Research in California.
Lamport's seminal work in distributed systems has laid the groundwork for the field. His most notable papers include:
These contributions have significantly improved the correctness, performance, and reliability of distributed systems.
In the early 1980s, while working on a personal book project, Lamport developed a set of macros based on Donald Knuth's TeX typesetting system. This set of macros became known as LaTeX. In 1983, Peter Gordon from Addison-Wesley approached Lamport to turn the LaTeX user manual into a book. Lamport released the first version of LaTeX in 1984 and subsequently authored "LaTeX: A Document Preparation System," which became widely popular.
In 1989, Lamport handed over the maintenance and development of LaTeX to Frank Mittelbach and his team, who released LaTeX2e in 1994, the current version of LaTeX (LaTeX History).
Lamport is also known for his work in temporal logic, introducing the Temporal Logic of Actions (TLA). He developed TLA+ as a language for specifying and reasoning about concurrent and reactive systems. His book, "Specifying Systems: The TLA+ Language and Tools for Hardware and Software Engineers," describes TLA+ in detail (TLA+).
Leslie Lamport has received numerous awards and honors for his contributions:
Lamport also holds honorary doctorates from several European universities, including the University of Rennes, Christian Albrechts University of Kiel, École Polytechnique Fédérale de Lausanne (EPFL), University of Lugano, and Nancy-Université.
His extensive body of work has made him one of the most influential figures in computer science, particularly in the fields of distributed systems and document preparation systems.
