Marshall Field (August 18, 1834 – January 16, 1906) was founder of Marshall Field and Company, the Chicago-based department stores.
Marshall Field was born on a farm in Conway, Massachusetts, the son of John Field IV and wife Fidelia Nash. His family was descended from Puritans who had come to America as early as 1650.
At the age of 17, he moved to Pittsfield, Massachusetts, where he first worked in a dry goods store. He left Massachusetts at the age of 18 for new opportunities in the rapidly expanding West. In 1856, at age 21, he went to live with his brother in Chicago, Illinois, and obtained employment at leading dry goods merchant Cooley, Wadsworth and Co., which was to become Cooley, Farwell & Co. in 1857. In 1862, Field purchased a partnership with the reorganized firm of Farwell, Field & Co.
