Louis Marius Moyroud (pronounced MOY-rood; February 16, 1914 – June 28, 2010) was a French-born American inventor who co-developed the phototypesetting process with Rene Alphonse Higonnet, which allows text and images to be printed on paper using a photoengraving process, a method that made the traditional publishing method of hot metal typesetting obsolete.
They thought that the process "was insane" and sought ways to produce directly the negative of the photographed page thus entirely eliminating the hot metal steps.
[1][2] They moved to the United States in 1948, where the Graphic Arts Research Foundation was created to foster further development of their photocomposing method, which was patented in the U.S. in 1957.
[3] The first book printed by their device was The Wonderful World of Insects in 1953 as a demonstration for MIT Press, which included 46 photographs on its 292 pages.
[3] Vannevar Bush called the process "a milestone in the graphic arts">[3] In 1954, The Patriot Ledger in Quincy, Massachusetts became the first newspaper to adopt the method for all of their printing.
