Willoughby M. McCormick (1864–1932), 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 February 1904, the third worst conflagration to hit an American city which over two days burned most of the city's central business district, north of the harbor waterfront with most of its then new rising skyscrapers.

However, a new five-story building was erected on the same site within 10 months in 1905. Willoughby's nephew Charles P. McCormick (1896–1970), began working for the company in the summer of 1912, during his high school years at the all-boys third oldest secondary school in America, The Baltimore City College before graduating in 1915, and going on to The Johns Hopkins University in its first years at the new Homewood campus in north Baltimore, and was later elected to the company Board of Directors in 1925.
