Phototypesetting Inventor Mayroud Dies at 96

By: E&P Staff

Electronics engineer Louis Marious Moyroud, co-inventor of phototypesetting, died at his home in Delray Beach, Fla., June 28 . He was 96.

Mayroud and IT&T colleague Rene Alphonse Higonet devised a phototypesetter in 1946 from work conducted in the early 1940s. The process began printing’s move from casting lines of lead type on Linotype and similar machines for use in creating molds from which heavy lead stereotype plates were cast.

What became their Photon machine 10 years later exposed images of individual letters on photosensitive paper as the operator keyed words. The paper could be pasted in galleys to form pages for photoengraving.

When Moyroud and Higonnet moved to the United States, the Graphic Arts Research Foundation helped them pursue photocomposition. The Patriot Ledger, Quincy, Mass., was the first U.S. newspaper to use the Photon machine.

“Once the high cost of the initial machines came down there was a major reduction in the cost of printing as it became more efficient,” National Inventors Hall of Fame Research Director Rini Paiva told The New York Times‘ Dennnis Hevesi.
