American Type Founders (ATF) was created in 1892 through the merger of 23 type foundries, and was the dominant American manufacturer of metal type until the 1940s. Despite a slow decline due to competition from composing machines such as the Lintoype, ATF manufactured type into the the 1970s. In 1986 the company was acquired by Kingsley, but in 1993, the ailing firm closed and auctioned off its type and equipment. The Cary Collection’s ATF matrix collection was acquired at that time. These matrices are brass molds employed in foundry-cast type.
