Alexander Vladimir d'Arbeloff (December 21, 1927 – July 8, 2008) was the Georgian-American co-founder of Teradyne, a multibillion-dollar Boston, Massachusetts-based manufacturer of automatic test equipment (ATE).
After graduating in 1949 with an SB in management from the MIT Sloan School of Management,[3] where he became a member of the Sigma Chi fraternity, he and fellow MIT alumnus Nick DeWolf founded and built Teradyne into one of the largest players in the global ATE market as integrated circuits became increasingly important to every aspect of modern technology.
Upon his retirement from Teradyne in 2000, he was succeeded by George Chamillard.
He was a Trustee of Partners Health Care System, Massachusetts General Hospital, and the New England Conservatory.
His brother, Dimitri was a President of Millipore Corp.
