Engstrom subsequently became head of RCA Laboratories and Vice President for research, leading RCA's successful World War II efforts in radar, radio, and acoustics. In the immediate aftermath of the war he participated in relief efforts for central Europe and Germany. In his role as head of research he led RCA's development of its first all-electronic color television system after the war, as well as national efforts including BMEWS and the TIROS weather-reporting satellite system. RCA's Astro-Electronics Division was the first organization within the electronics industry to develop space electronic systems. Engstrom became RCA's President and Chief Executive Officer, serving on its board until 1971. He served on numerous national advisory panels, was a founding member of the United States National Academy of Engineering, and received honorary degrees from eighteen colleges and universities including Drexel Institute of Technology, Findlay College, and New York University. He was an IEEE Fellow and received numerous awards, including the IEEE Founders Medal in 1966 "For his leadership in management and integration of research and development programs and for his foresighted application of the systems engineering concept in bringing television to the public."
During the 1930s, Engstrom led RCA's research and development efforts for television, culminating in the company's first commercial black and white television system. Its first complete test took place in 1939, with a transmitter installed on the 85th floor of the Empire State Building. A mechanical scanner provided a 120-line, 24-frame picture from live and film subjects, and extensive field tests took place with the first cathode ray tube receivers. Although picture quality was poor, the tests conclusively proved the feasibility of television broadcasting. This effort was one of the earliest applications of a "system engineering" approach, now standard practice on large technical programs.
Civic and Christian Leader
Engstrom was prominent in a number of educational, professional, and civic organizations. He was active in the Princeton chapters of the American Red Cross, Sigma Xi, the Rotary Club and the YMCA-YWCA. He was also a member of Westerly Road Church where he served many years as the president of the board of trustees. Engstrom was an active Christian leader, writing for Campus Crusade for Christ:
There is one fundamental concept I have learned very clearly from my business experience. There is a need for a definite and clearly understood charter for one's operations. Having established that charter, there is need for complete belief in it and in the program which it provides. In the Christian life the Bible is our charter. It is the supreme authority for our lives and it is sufficient for our needs. I believe it is a requirement of paramount importance that Christ be the Lord of our whole life, and that our allegiance to Him be in no way divisible.
