J. Roy Carroll Jr.

J. Roy Carroll Jr. FAIA (1904–1990) was an American architect in practice in Philadelphia from 1935 to 1985. He was president of the American Institute of Architects from 1963 to 1964.

Jefferson Roy Carroll Jr. was born September 25, 1904, in Philadelphia. He was educated at West Philadelphia High School and the University of Pennsylvania, graduating in 1928 with an M.Arch. During school vacations he worked for Bunting & Shrigley, DeArmond, Ashmead & Bickley and Harry Sternfeld. He rejoined Sternfeld after his graduation, and was later made an associate in his firm, and was also employed as an instructor in architecture at Penn. He left Sternfeld in 1935 to open his own office, and in 1940 was appointed assistant professor of architecture at Penn. In 1941 he was awarded the Henry Gillette Woodman Traveling Scholarship to study the practice of industrial design under wartime conditions and needs, and upon his return reorganized the university's design department to meet those needs. He resigned from the university in 1945 to focus on practice, forming a partnership with John T. Grisdale. In 1946 it was expanded to include William L. Van Alen. They worked together in the firm of Carroll, Grisdale & Van Alen until 1974, when Carroll reorganized the practice as J. Roy Carroll Jr. & Partners with Elisha Safford Jr., Joseph C. Didinger, George C. Felton, Clarke Bachman and Collins S. Keller. This firm was dissolved in 1977, and Carroll practiced independently until his retirement in 1985.

Carroll joined the American Institute of Architects in 1936, and was elected a Fellow in 1954. He filled several local and regional offices of the AIA, serving as founding president of the Pennsylvania Society of Architects in 1945–46, Philadelphia chapter president in 1952–53 and Mid-Atlantic regional director for 1956–59. In 1959 he was elected secretary of the national organization and as first vice president in 1962. In 1963 he was elected to a single term as president. During Carroll's presidency, the AIA initiated the process to construct the new AIA Headquarters, which would not be completed until 1973. His service continued after his presidency, serving as president of the AIA Foundation from 1964 to 1968 and as chancellor of the College of Fellows in 1968–69. Carroll was also made an honorary member of the Royal Architectural Institute of Canada, the Society of Architects of Mexico and the Philippine Institute of Architects and in 1976 was elected a Benjamin Franklin fellow of the Royal Society of Arts.

Carroll was married twice: first to Doris Packard, who died in 1980, and second to Ann Haggerty. He had three children, all with his first wife. He lived in Swarthmore, and died July 18, 1990, in a hospital in Chester.
