French's is an American manufacturer of prepared mustard condiment. Created by Robert Timothy French, French's mustard debuted to the world at the 1904 St. Louis World's Fair. By 1921, French's Mustard had adopted its trademark pennant and begun advertising to the general public.
Brothers Robert and George French bought a flour mill in 1883 in Fairport, New York. It burned down in 1884, and they relocated the flour mill to Rochester, New York. They named their mill the R.T. French Company. Robert French died in 1893, and brother George became company president. George (who developed the creamy yellow mustard) and another brother, Francis, introduced French's mustard in 1904.
When located in Rochester, New York as an independent company well into the late 1960s and 1970s, the plant was located at 1 Mustard Street. This address in the 14609 zip code is now home to a variety of professional offices and public agencies. During its heyday, the company was a sponsor of the local weather forecast, featuring its address prominently in television advertising. They also were a prominent sponsor of the Rochester Red Wings baseball club, often in conjunction with a local brand of hot dogs, Tobin's First Prize.
Although at one time its product line extended to canned spices of all types and powdered soup mixes, French's currently primarily markets prepared mustards.
All French's products are manufactured in the United States, though no longer in Rochester, New York. They are sold in Canada, Europe, the Middle East and Asia.
