equipment and also constructed entire cable systems. Simons designed one of the first converters and the two most important pieces of the early test equipment, the Model 704 Field Strength Meter and Model 900 Sweep Frequency Generator. He also authored a seminal technical handbook on cable television systems, and served on national and international engineering standards committees. Fellow cable engineer Archer Taylor stated that Simons was seen as the leading technical expert at Jerrold for over two decades.


Early years

Born in Philadelphia, Pennsylvania, Simons' interest in radio began at an early age, and he obtained his amateur radio license (callsign W3UB) in 1930. Simons started his career as a radio troubleshooter for RCA in 1932 in Camden, and worked for RCA while he attended college. In 1938 he graduated from the

From 1942 until 1946 he was the chief instructor for the RCA Signal Corps School. Along with teaching operation and repair of various devices, he wrote instruction manuals on oscilloscope use and synchronous motors. He moved to Kansas City, Missouri, in 1946 and was the chief television instructor at Central Radio School until 1948. Simons then worked for Sylvania for about a year developing television tuners and an indoor antenna. In 1952 he formed a partnership to design and manufacture direct-coupled oscilloscopes. Due to lack of funding, they ultimately were not produced.


Jerrold years

Simons began at Jerrold Electronics Corporation as a part-time consulting engineer in 1951. His first project was to design a high-to-low

. He and other Jerrold engineers worked out of Simons' personal laboratory located on the second floor of a stained glass factory in Bryn Athyn, Pa., until a new Jerrold lab was built in Hatboro, Pa., in 1955. Simons characterized his role at Jerrold in his resume: "Three of us were primarily responsible for equipment design in the early years. Donald Kirk was talented in coming up with new ideas, my contribution was often in getting a system to work, and Henry Arbeiter took all the bright ideas and made them producible."Simons resume Other engineering colleagues included Eric Winston, Mike Jeffers, Frank Ragone, Caywood Cooley, Vic Nicholson, Len Ecker, and Bill Felsher. Simons successively became chief engineer, chief test equipment engineer, vice president and director of advanced development. Some of his noteworthy designs include the Model 704B Field Strength Meter. In a technology area based on rapid and constant change, the 704B was of note in being in production and use for more than 20 years The 704 name is honored even today in a fraternal organization of its user

However, not only was he a contributor to cable television but he volunteered his unique knowledge to the faculty of the University of Pennsylvania Medical School in developing optical imaging systems for the detection of breast cancer and brain function. This deep knowledge and facile handiwork made possible the perfection of devices that are now the focus of new types of medical devices that make possible non-invasive and highly sensitive detection of brain function, muscle function and cancer detection. Simons will be long remembered for his generous and far-reaching knowledge of electronic circuits.
