Lewis M. Branscomb

American physicist (1926–2023)

Lewis McAdory Branscomb (August 17, 1926 – May 31, 2023) was an American physicist, government policy advisor, and corporate research manager. He was best known for being head of the National Bureau of Standards and, later, chief scientist of IBM; and as a prolific writer on science policy issues.

Branscomb received a B. A. in physics from Duke University in 1945. He joined the navy reserves, where he deployed to the Philippines as a junior officer. He received his Ph. D. from Harvard in 1949, and remained two additional years as a junior fellow. These years, and his interactions with scholars as diverse as Clyde Kluckhohn, Merle Fainsod, William Fairbank, and Edward Purcell, kindled a lifelong interest in broad policy issues. No less remembered from this period, Branscomb played the role of "Professor" in Tom Lehrer's 1951 The Physical Revue, premiering several Lehrer songs in early versions.

Branscomb joined the U. S. National Bureau of Standards (now NIST) in 1951 as a research physicist. Rising in management through several levels, he became the founding chair of the Joint Institute for Laboratory Astrophysics (JILA), and was in 1969 appointed director of the National Bureau of Standards by President Nixon. In 1972, Branscomb moved to IBM Corporation as vice president and chief scientist, and was later a member of the IBM Corporate Management Board. In 1986, he moved to Harvard as director of the Science, Technology and Public Policy Program in the John F. Kennedy School of Government at Harvard University, holding that position until 1996.

Branscomb was a member of President Johnson's Science Advisory Committee (PSAC) from 1964 to 1968, during which time (a critical early period of the Apollo program) he chaired PSAC's Panel on Space Science and Technology. Branscomb was a Fellow of National Academy of Public Administration (United States).

Branscomb died on May 31, 2023, at the age of 96.

Branscomb was an author of more than 500 scholarly publications and 11 books. He served on the boards of several corporations (including General Foods and Mobil) and many non profit organizations. For a continuous period of 57 years Branscomb and/or his father, B. Harvie Branscomb, served as a trustee of Vanderbilt University.
