Robert M. Gray (born November 1, 1943[1]) is an American information theorist, and the Alcatel-Lucent Professor of Electrical Engineering at Stanford University in Palo Alto, California. He is best known for his contributions to quantization and compression, particularly the development of vector quantization.


Gray received the 2008 Claude E. Shannon Award from the IEEE Information Theory Society, for his fundamental contributions to information theory, particularly in the area of quantization theory.[2] He was also the recipient of the 2008 IEEE Jack S. Kilby Signal Processing Medal,[3][4] the 1998 Golden Jubilee Award for Technological Innovation from the IEEE Information Theory Society,[5] the 1993 IEEE Signal Processing Society Award,[6] and the 1984 IEEE Centennial Medal[1]. Gray received the 2002 Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring from the National Science Foundation.[7]

Amongst other honors, he was elected to the National Academy of Engineering in 2007, and received the IEEE Third Millennium Medal in 2000.

Early life[edit]

Born in 1943 in San Diego, Gray grew up in Coronado, California. He was a middle child in a family of five.

Gray followed his two older brothers to the Massachusetts Institute of Technology. He earned the B.S. and M.S. in Electrical Engineering from MIT in 1966, where he was a classmate of Lawrence Rabiner. Gray earned the Ph.D. in Electrical Engineering from University of Southern California in 1969; his Ph.D. advisor was Robert A. Scholtz. During his graduate school years, he played guitar in the rock band "MCF".

He began his career at the US Naval Ordnance Laboratory, following a family naval tradition.


Gray has written or co-authored a number of technical texts, including:

  • Toeplitz and Circulant Matrices (1971, revised 2006)
  • Probability, Random Processes and Ergodic Properties (1988, revised 2007)
  • Introduction to Statistical Signal Processing (1986, revised 2007)
  • Entropy and Information Theory (1991, revised 2007)
  • Source Coding Theory (1990)
  • Vector Quantization and Signal Compression (1992)

Gray is also an amateur historian and has collected together some historical letters from diplomats into books:

  • Amy Heard: Letters from the Gilded Age (2005)
  • Max&Max (2005)

Notable professional service[edit]

Gray is currently Editor-in-Chief of Foundations and Trends in Signal Processing. He has also been Editor-in-Chief of the IEEE Trans. on Information Theory (1981–1983), and served on the IEEE Information Theory Society Board of Governors (1974–1980, 1984–1987) and IEEE Signal Processing Society Board of Governors (1999–2001).
