Leslie B. Lamport (born February 7, 1941) is an American computer scientist and mathematician.

Lamport is best known for his seminal work in distributed systems, and as the initial developer of the document preparation system LaTeX and the author of its first manual.

1960

A graduate of Bronx High School of Science, Lamport received a B.S. in mathematics from the Massachusetts Institute of Technology in 1960, followed by M.A. (1963) and Ph.D. (1972) degrees in mathematics from Brandeis University.

His dissertation, The analytic Cauchy problem with singular data, is about singularities in analytic partial differential equations.

1970

Lamport worked as a computer scientist at Massachusetts Computer Associates from 1970 to 1977, Stanford Research Institute (SRI International) from 1977 to 1985, and Digital Equipment Corporation and Compaq from 1985 to 2001.

1980

When Donald Knuth began issuing the early releases of TeX in the early 1980s, Lamport — due to his personal need of writing a book — also began working on a set of macros based on it, hoping that it would later become its standard macro package.

1983

This set of macros would later become known as LaTeX, for which Lamport would subsequently be approached in 1983 by Peter Gordon, an Addison-Wesley editor, who proposed that Lamport turn its user manual into a book.

1984

In September 1984, Lamport released version 2.06a of the LaTeX macros, and in August 1985, LaTeX 2.09 — the last version of Lamport's LaTeX — would be released as well.

1989

Meanwhile, Addison-Wesley released Lamport's first LaTeX user manual, LaTeX: A Document Preparation System, in 1986, which purportedly sold "more than a few hundred thousands" copies, and on August 21, 1989, at a TeX User Group meeting at Stanford, Lamport would agree to turn over the maintenance and development of LaTeX to Frank Mittelbach, who, along with Chris Rowley and Rainer Schöpf, would form the LaTeX3 team, subsequently releasing LaTeX 2e, the current version of LaTeX, in 1994.

Lamport is also known for his work on temporal logic, where he introduced the temporal logic of actions (TLA).

Among his more recent contributions is TLA+, a language for specifying and reasoning about concurrent and reactive systems, which he describes in the book Specifying Systems: The TLA+ Language and Tools for Hardware and Software Engineers. He defines TLA+ as a "quixotic attempt to overcome engineers' antipathy towards mathematics".

1991

He was elected a member of the National Academy of Engineering in 1991 for contributions to the theoretical foundations of concurrent and fault-tolerant computing.

2001

In 2001 he joined Microsoft Research in California.

Lamport's research contributions have laid the foundations of the theory of distributed systems.

Among his most notable papers are

These papers relate to such concepts as logical clocks (and the happened-before relationship) and Byzantine failures.

They are among the most cited papers in the field of computer science, and describe algorithms to solve many fundamental problems in distributed systems, including:

In honor of Lamport's sixtieth birthday, a lecture series was organized at the 20th Symposium on Principles of Distributed Computing (PODC 2001).

2003

He also received five honorary doctorates from European universities: University of Rennes and Christian Albrechts University of Kiel in 2003, École Polytechnique Fédérale de Lausanne (EPFL) in 2004, University of Lugano in 2006, and Nancy-Université in 2007.

2004

In 2004, he received the IEEE Emanuel R. Piore Award.

2005

In 2005, the paper "Reaching Agreement in the Presence of Faults" received the Dijkstra Prize.

2008

In 2008, he received the IEEE John von Neumann Medal.

2011

In 2011, he was elected to the National Academy of Sciences.

2013

Lamport was the winner of the 2013 Turing Award for imposing clear, well-defined coherence on the seemingly chaotic behavior of distributed computing systems, in which several autonomous computers communicate with each other by passing messages.

He devised important algorithms and developed formal modeling and verification protocols that improve the quality of real distributed systems.

These contributions have resulted in improved correctness, performance, and reliability of computer systems.

Lamport was born into a Jewish family in Brooklyn, New York, the son of Benjamin and Hannah Lamport (née Lasser).

His father was an immigrant from Volkovisk in the Russian Empire (now Vawkavysk, Belarus) and his mother was an immigrant from the Austro-Hungarian Empire, now southeastern Poland.

Lamport received the 2013 Turing Award for "fundamental contributions to the theory and practice of distributed and concurrent systems, notably the invention of concepts such as causality and logical clocks, safety and liveness, replicated state machines, and sequential consistency" in 2014.

2014

He was elected to Fellow of Association for Computing Machinery for fundamental contributions to the theory and practice of distributed and concurrent systems in 2014.
