Tolbert Lanston (3 February 1844, Troy, Ohio – 18 February 1913) was the American founder of Monotype, inventing a mechanical typesetting system patented in 1887 and the first hot metal typesetter a few years later.

He was born in a poor family. He quit school at the age of 15, he was a volunteer in the Federal Army during the American civil war. Last rank was sergeant.
After 1865 he worked at the Pension-Department of the American Government. Here he met colonel Seaton. Saeton's father, a printer, produced for the government. Here Lanston learned about printing.
Although Lanston was an inventor, he had no education at all as an engineer.
He did start his inventions to create a type-setting machine, first with the financial help of Seaton, later from J. Maury dove, coal-merchant in Washington.
Letters sent to the Patent-bureau with specifications sent at:
The idea was to make lead type for printing, with two machines, the first to produce two paper-tapes, these two paper-tapes controlling the second machine to produce the type. Lanston made a series of prototypes.
John Sellers Bancroft of Sellers & Co in Philadelphia was asked to help with the development of the machine.
This man made a series of important improvements. A wedge to govern the width of the character. This wedge makes the same movement as the diecase with the matrices, in one direction. The matrices are ordered in the diecase, each row has only matrices for characters of the same width. The wedge controls the opening in the mould.
Compressed air was used to control the movements of the matrices above the mould of the machine.
This machine was capable to produce filled lines, by controlling the width of the spaces, with two extra wedges. The accuracy of the machine was 2000 parts in 1 inch.
The first commercial machines were available around 1897. These machines had only room for 132 matrices. A few of these machines were sent to England.
Later types had die-cases with 15*15 and 17*15 or even 16*17 matrices.[1]
