SOLOMON JAN BUCHSBAUM, senior vice-president, technology systems, AT&T Bell Laboratories, and adviser to the administrations of five U.S. presidents, died of multiple myeloma on March 8, 1993, at the age of sixty-three.

Sol, as he was known to his friends, was born in Stryj, Poland, on December 4, 1929. He lost both parents and a sister in the holocaust, and his early life was difficult. He emigrated to Canada in 1947 and received his bachelor's and master's degrees from McGill University in 1952 and 1953, respectively. He received his Ph.D. degree in physics from the Massachusetts Institute of Technology (MIT) in 1957. In 1955 he married Phyllis Isenman, and they had three children, Rachel Joy, David Joel, and Adam Louis. Sol became a U.S. citizen in 1963.

Sol cared deeply about the health of the U.S. technical enterprise, including the universities, government, and private research and development laboratories that compose it. His contributions were always distinguished by his personal enthusiasm, energy, and competitive spirit and by an uncompromising devotion to technical excellence and personal integrity. As a leader and adviser for large scientific-technological programs, he brought keen insights into technical issues and policy matters alike, quality judgment, and an ability to apply reason to very complex and difficult situations. He was remarkably able to convey his insights to others. He made many friends.
