Willoughby M. McCormick started the business in Baltimore at age 25 in 1889. From one room and a cellar, the initial products were sold door-to-door and included root beer, flavoring extracts, fruit syrups and juices. Seven years later, McCormick bought the F.G. Emmett Spice Company and entered the spice industry. In 1903, Willoughby and his brother Roberdeau incorporated the company in Maine; it was reincorporated in Maryland in 1915. Most of the company's assets and records were destroyed in the Great Baltimore Fire of 1904, though a new five-story building was erected on the same site within 10 months. Willoughby's nephew Charles P. McCormick began working for the company in the summer of 1912 and was elected to the Board of Directors in 1925.

Willoughby died on November 4, 1932, and Charles was elected President and Chairman of the Board at age 36. The big "Mc" became a trademark for nearly all U.S. products in 1941.
