His parents were Abraham and Feijga Frohman, Polish Jews who had emigrated to the Netherlands in the early 1930s to escape rising anti-Semitism in Poland.

In 1942, after the German invasion of the Low Countries and as the Nazi grip on Holland’s Jewish community tightened, his parents decided to give their child to acquaintances in the Dutch resistance who placed him with the Van Tilborghs, an orthodox Christian farming family that lived in the village of Sprang-Capelle in the region of North Brabant near the Belgian border.

After graduating from the Technion in 1963, Frohman traveled to the United States to study for his master's and Ph.D. at the University of California, Berkeley.

In 1969, after completing his Ph.D., he followed former Fairchild managers Gordon Moore, Robert Noyce, and Andrew Grove to Intel Corporation, which they had founded the previous year.

[3] It was while troubleshooting a fault in an early Intel product that Frohman in 1970 developed the concept for the EPROM, the first non-volatile semiconductor memory that was both erasable and easily reprogrammable.

Typically, the data had to be “burned in” at the factory: physically embedded on the chip through a process called “masking” that generally took weeks to complete.

After inventing the EPROM, Frohman left Intel to teach electrical engineering at the University of Science and Technology in Kumasi, Ghana.

On his return to Israel, Frohman taught at the School of Applied Sciences at Hebrew University of Jerusalem and worked as a consultant to Intel on the side.
