After the war, Goldsmith became director of research for the Marconi Wireless Telegraph Company of America and in 1919 RCA's director of research. In 1923 he was named RCA's Chief Broadcast Engineer and in 1927 Chairman of the Board of Consulting Engineers of the National Broadcasting Company. He remained with RCA as vice president and general manager until 1931, and was awarded RCA's first production television tube with an inscription reading "RCA Laboratory’s Award for Outstanding Work in Research presented to Alfred Norton Goldsmith for his early recognition of the importance of a tri-color kinescope and for his concept of means for accomplishing it."
Goldsmith was made an IRE Fellow in 1915, its president in 1928, and served on its board of directors for 51 years. In 1941 he was awarded the IRE Medal of Honor "for his contributions to radio research, engineering, and commercial development, his leadership in standardization, and his unceasing devotion to the establishment and upbuilding of the Institute and its proceedings", the IEEE Founders Medal in 1954,[1] and the first IEEE Haraden Pratt Award in 1972, to honor "outstanding service to the IEEE."[2]
Since 1975 the Alfred N. Goldsmith Award for Distinguished Contributions to Engineering Communication Award has been given by IEEE Professional Communication Society in his honor.
