Vossberg entered the profession as a radio engineer for RCA and designed circuits and established radio facsimile facilities for the Office of War information. Later he became Chief Engineer for Standard Electronics Research Corporation, where his duties were to originate and direct the research and development programs and supervise engineering and technical personnel in electronics, x-rays, communication, instrumentation and process controls. He was also Vice President of Research and Developments, Inc., and Vice President of Industrial Gauges Corporation.
After the war, Vossberg set out to apply electronics technology to industrial applications. Electron-Machine Corporation was formed in 1946 for the purpose of designing automatic electronic gaging and indicating equipment. The company was established in the back of a radiator repair shop in Lynbrook, New York. Instruments for diameter and thickness measurements for steel and cable products were conceived, developed, and licensed to other manufacturers. These instruments included the first commercial x-ray thickness gage, optical cable diameter gages, and an industrial process control computer. In 1950 he, in partnership, formed the Industrial Gauges Corporation and later established Research Developments, Inc., as a subsidiary. This expansion provided the manufacturing facilities for the products developed by the Electron-Machine Company.
In 1952, Electron-Machine Corporation moved to Umatilla, Florida, where operations continue today. The abundant living attributed to Florida influenced Vossberg's decision to move the company to Umatilla, where laboratory buildings were constructed between two beautiful lakes to house the electronic and chemical sections. The location was chosen because it was “conducive to scientific research and can account for the Laboratories producing near miracles.”
The early efforts of Electron-Machine Corporation were directed toward solving specific problems of a custom nature involving mainly engineering development and limited production. These practices were carried into the early 1960s when a series of products appeared as a result of these custom applications. In 1963, it became apparent that the efforts of Electron-Machine Corporation were divided into a systems capability and a product line. With the limited resources available, Vossberg had to make a choice: Vossberg decided to concentrate Electron-Machine Corporation's total effort towards further development and exploitation of its product line.
The first in-line process refractometer was developed to fulfill a need within the developing concentrated Citrus industry, and the use of refractometers on numerous applications in the food, chemical, and pulp/paper industries continues throughout the world today.
