The story

Brothers Anton and Franz Hamm, who were gunsmiths, founded the company in 1878 to build agricultural equipment. The company built their first diesel-powered road roller in 1911, from a design by a second-generation Hamm, Hans Hamm. This was at a time when most rollers where steam powered. In 1928, the company abandoned all other product lines to concentrate on road rollers. Hamm produces the first all-wheel drive-all-wheel steering double-drum. The company introduced an all-wheel steering and all-wheel drive rubber-wheeled roller in 1963, and then rolled out its oscillating vibratory roller in 1989.

In 1999, the Wirtgen Group GmbH announced that it would purchase Hamm AG; the transaction was completed in March 2000.
