If you have information to add to this entry, please contact the Site Historian.

Louis Allis left his father's company, E. P. Allis & Co., just before the merger that created Allis-Chalmers in 1901, and established Mechanical Appliance Co., which immediately began manufacturing dynamos and motors. In 1922 they changed their name to Louis Allis Co. The company seems to have undergone changes in 2002 but it remains in business today.

Allis was an OEM supplier for Oliver Machinery Co.
