Monotype Imaging Holdings Inc., founded as Lanston Monotype Machine Company in 1887 in Philadelphia by Tolbert Lanston, is an American company that specializes in digital typesetting and typeface design for use with consumer electronics devices. Incorporated in Delaware and headquartered in Woburn, Massachusetts, the company has been responsible for many developments in printing technology—in particular the Monotype machine, which was a fully mechanical hotmetal typesetter, that produced texts automatically, all single type. Monotype was involved in the design and production of many typefaces in the 20th century. Monotype developed many of the most widely used typeface designs, including Times New Roman, Gill Sans, Arial, Bembo and Albertus.

Tolbert Lanston was the American founder of Monotype, inventing a mechanical typesetting system patented in 1887 and the first hot metal typesetter a few years later.
