In 1953, Rayteheon delivered the first order for CK722. Introduced by Raytheon in 1953, the CK722 was the first low cost junction transistor available to the general public.

Jack Ward reports that

“It was an instant success. Countless “build it yourself” articles were published in the popular electronics press and hobbyist magazines. Many of the talented and dedicated professionals and amateurs who have been responsible for the tremendous rise of the electronics industry over the past five decades can still remember the time, when, as a young hobbyist, they were able to scrape together enough money (maybe through saving allowance or cutting the neighbor’s grass) to buy that first CK722.

…, there never would have been a CK722 transistor without the insight, dedication and hard work of Norm Krim and his team during those exciting times many years ago. I have found great pleasure in documenting the history of the CK722, mostly because of the unexpected opportunity to communicate with so many others who were personally affected by the CK722. I never imagined that almost 50 years after first encountering one of these marvels, I’d have the opportunity to work who those who made it possible and with those who shared my experiences.”

Doesn’t it remind you of some contemporary story?
