Inventors Phototypesetting
Phototypesetting Machines
Two Frenchmen, Rene Alphonse Higonnet and Louis Marius Moyroud, developed a successful phototypesetter that used a strobe light and a series of optics to project characters from a spinning disk onto photographic paper.

According to Britannica Encyclopedia*, "the first mechanical phototypesetters involved the adaptation of existing typesetters by replacing the metal matrices with matrices carrying the image of the letters and replacing the caster with a photographic unit. The industrial application of this idea resulted in the Fotosetter (1947), a phototypesetter... The first revolutionary application of this notion was the Lumitype, invented as the Lithomat in 1949 by two Frenchmen, René Higonnet and Louis Moyroud. Executed by phototypesetting, The Marvelous World of Insects was done on their machine in 1953. The first model had an attached keyboard. Later models with a separate keyboard printed more than 28,000 characters per hour... ...a third generation of phototypesetters appeared in the 1960s, in which all mechanical moving parts were eliminated by omitting the use of light and therefore omitting the moving optical device responsible for operating in its field."

Louis Marius Moyroud and Rene Alphonse Higonnet developed the first practical phototypesetting machine.

Using phototypesetting, a direct image of the text is obtained, positive or negative, according to need, on a photosensitive, usually transparent surface by exposing the surface to light through transparent matrices, negative or positive, of the letters and symbols.
