Louis Moyroud

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.

Biography Louis Marius Moyroud was born on 16 February 1914 in Moirans, Isère, France. He attended engineering schools and received a government scholarship to study engineering at the École nationale supérieure d'arts et métiers, graduating in 1936.

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. While the process they developed had higher initial costs, Rini Paiva of the National Inventors Hall of Fame described how the photocomposing process "definitely revolutionized the printing industry", allowing books, magazines and newspapers to be printed more easily and at substantially lower cost. Vannevar Bush called the process "a milestone in the graphic arts"> In 1954, The Patriot Ledger in Quincy, Massachusetts became the first newspaper to adopt the method for all of their printing.

Higonnet and Moyroud were inducted into the National Inventors Hall of Fame in 1985.

Moyroud died at age 96 on June 26, 2010, in his home in Delray Beach, Florida. He was survived by three sons. His wife, Marie-Thérèse Meynet, had died in 2008.
