Holyoke was an American automobile company started in Holyoke, Massachusetts in 1899.[1] The first car had a two-cylinder, 7 hp motor.[2] The cars were designed by Charles Robert Greuter, born Philadelphia, PA, March 26, 1861, and educated St. Gallen and Winterthur, Switzerland.[3] In 1900 the Springfield Republican reported: "The president of the Holyoke motor works is Charles R. Greuter, who started the business of making gasoline carriages and wagons about a year ago in the old Standard machine company building, and at present employs about 40 men."[4] In 1903 the company was acquired by the Matheson Motor Car company.[5] Greuter then served as a director of that company.[6]
