Linotype machine
From 1900 to 1983, Stempel had an exclusive relationship with Mergenthaler Linotype Company, as one of just a few producers of matrices for the Linotype machine worldwide and the only one in Europe. Starting in 1925, Stempel types were distributed in the United States by Continental Type Founders Association. Linotype AG became the majority stockholder in 1941. In 1977, Stempel began manufacturing Phototypesetting equipment.
