Heintz and Kaufman
This entry is dedicated to the Heintz and Kaufman manufacturing business.
The Heintz and Kaufman factory operation was a pre-cursor to launch of the EIMAC vacuum tube plant in the early 1930's.
The H&K firm has a rich history of manufacturing aeronautical radio transmitters and possibly receivers(?) and a rare facet that H&K supplied transmitters used for conveying the AC generator status, possibly data(?) from the generating stations located on the Feather River in Northern California back to the Bay Area for the power company (PG&E). source: https://ethw.org/Oral-History:Leonard_Fuller
The following was in a batch of "stuff" initially given to Mr. Marshall Loring who was the last manager of the Eimac'ers Retiree gatherings which ceased operation shorty before he moved to Tennessee. In the stuff I found a great photo of the Heintz Kaufman factory signed by one of the employees dated 6/7/1935. It was presented to one of the employees in the photo, Mr Irv Coutts. Then, sometime at a future date, he and perhaps several other H&K employees left to go to work for Eitel-McCullough Inc. since they were rapidly growing and hiring in the area.
Along with the photo I found a lengthy letter describing the life of that employee, Irv Coutts, by his wife whom he later met at Eimac. Its all very touching to read her description of their meeting, getting married, working in the same place. That letter and photograph is reproduced here with permission.
- While this a new page, it's an open invitation to you as readers who may have historic information like photo's, letters, anecdotes and other documents to capture this remarkable history.
