Historical Note

When RCA Laboratories was established in 1941, the top two executives were Vice-President, RCA Laboratories Otto S. Schairer and Research Department Director Ralph R. Beal. In 1943, Beal was replaced by Elmer W. Engstrom.

In 1945, Schairer stepped down in favor of Charles B. Joliffe, who was succeeded by Engstrom in 1951, with Irving Wolff taking over the Research Department. Promoted to Executive Vice-President, Research and Engineering in 1954, Engstrom also continued as Vice-President, RCA Laboratories until Douglas H. Ewing’s appointment the following year. Engstrom was promoted again in 1955 to Senior Vice-President, but remained responsible for Research and Engineering.

Ewing was promoted to Vice-President, Research and Engineering in 1957 and James Hillier took over his previous position. George H. Brown replaced Ewing in 1961 and the Research Department, where Humboldt W. Leverenz had replaced Wolff in 1959, was abolished.

James Hillier succeeded Brown in 1968, while William M. Webster took over RCA Laboratories. In 1976, Hillier moved into an advisory position and William C. Hittinger was appointed Executive Vice-President, Research and Engineering. Hittinger served until a reorganization in 1983 eliminated Research and Engineering.

James J. Tietjen, who had succeeded Webster as Vice-President, RCA Laboratories in 1985, became the first President of the David Sarnoff Research Center when it was incorporated as a subsidiary of SRI in 1987. James Carnes was appointed President in 1990 and served until 2002 when he was replaced by Satyam C. Cherukuri. Carnes returned as interim President in 2006-2007. After brief terms as president by Don Newsome and Mark A. Clifton, the position was eliminated when the Sarnoff Corporation was integrated into SRI in 2011.
