**Toby Berger** (September 4, 1940 – May 25, 2022) was an American information theorist.

Berger was born in New York City, to a Jewish family.^{ [1] } He received a bachelor's degree in electrical engineering from Yale University in 1962, and doctoral degree in applied mathematics from Harvard University in 1968.

From 1962 to 1968 he was also a senior scientist at Raytheon. From 1968 to 2005 he taught at Cornell University, and in 2006 joined the University of Virginia. His primary interests were in information theory, random fields, communication networks, video compression, signature verification, coherent signal processing, quantum information theory, and bio-information theory.

Berger was elected a member of the National Academy of Engineering in 2006 for contributions to the theory and practice of lossy data compression.^{ [2] } He was also an IEEE Fellow, a President of the IEEE Information Theory Society (1979), and a member of the American Association for the Advancement of Science, the American Society for Engineering Education, Sigma Xi, and Tau Beta Pi. He was the Editor-in-Chief of the IEEE Transactions on Information Theory from 1987 to 1989. He received the 2002 Claude E. Shannon Award for his contributions to information theory, and the 2011 IEEE Richard W. Hamming Medal.^{ [3] } Berger was also a co-founder of SightSpeed, a company which originated in his lab at Cornell University, which was acquired by Logitech in 2008. In 2017 he co-founded with his former student a Wi-Fi networks technology company, Cayuga Wireless, that is based on their multiple access research for multiuser physical layers.

**Elwyn Ralph Berlekamp** was a professor of mathematics and computer science at the University of California, Berkeley. Berlekamp was widely known for his work in computer science, coding theory and combinatorial game theory.

**David S. Slepian** was an American mathematician. He is best known for his work with algebraic coding theory, probability theory, and distributed source coding. He was colleagues with Claude Shannon and Richard Hamming at Bell Labs.

**Solomon Wolf Golomb** was an American mathematician, engineer, and professor of electrical engineering at the University of Southern California, best known for his works on mathematical games. Most notably, he invented Cheskers in 1948. He also fully described polyominoes and pentominoes in 1953. He specialized in problems of combinatorial analysis, number theory, coding theory, and communications. Pentomino boardgames, based on his work, would go on to inspire *Tetris*.

**Peter Elias** was a pioneer in the field of information theory. Born in New Brunswick, New Jersey, he was a member of the Massachusetts Institute of Technology faculty from 1953 to 1991. In 1955, Elias introduced convolutional codes as an alternative to block codes. He also established the binary erasure channel and proposed list decoding of error-correcting codes as an alternative to unique decoding.

**Jacob Ziv** was an Israeli electrical engineer and information theorist who developed the LZ family of lossless data compression algorithms alongside Abraham Lempel.

**Irving Stoy Reed** was an American mathematician and engineer. He is best known for co-inventing a class of algebraic error-correcting and error-detecting codes known as Reed–Solomon codes in collaboration with Gustave Solomon. He also co-invented the Reed–Muller code.

The **Claude E. Shannon Award** of the IEEE Information Theory Society was created to honor consistent and profound contributions to the field of information theory. Each Shannon Award winner is expected to present a Shannon Lecture at the following IEEE International Symposium on Information Theory. It is a prestigious prize in information theory, covering technical contributions at the intersection of mathematics, communication engineering, and theoretical computer science.
