If you have been in the phase converter industry for any length of time, you have most likely heard of Larry Katz. A mad genius electrical engineer who took over Kay Industries from his late father Aaron and late elder brother Stephen in 1972. Then, pioneered more modification to the product and its brands in a ten year span than had been seen in the industry in its entire existence.

Aaron and Steven Katz ( Larry’s father and younger brother)took control of Kay Industries in 1971. Upon their passing about 30 years later, Larry, an employee until then, inherited the business. I joined the company in 1990 as Plant Manager and knew them all very well. At the time I joined the company annual sales amounted to less than 700k. In the ensuing 13 years that number increased to about 1.2M as the result of many manufacturing improvements and innovations. Larry did a fine job, and I am proud to say that I was there, and I saw it happen.
