In August 1917, Eugenia Duke and her daughter Martha began selling sandwiches at YMCA-run Army canteens to help make money for her family. Due to requests from soldiers at nearby Camp Sevier which was a National Guard training camp and other customers (she had quickly expanded the places to which she sold her sandwiches), she started bottling her mayonnaise around 1923. In November 1928, she was a speaker in Boston at the Mayonnaise Manufacturer's Convention.[10] Unable to keep up with demand, she sold it to the C. F. Sauer Company in 1929.
With C. F. Sauer
In 1929, the C.F. Sauer Company in Richmond, Virginia, purchased Duke's products and Duke's Mayonnaise became the company's flagship product.[11] The plant is located in Mauldin, South Carolina which is southeast of Greenville. The facility was featured in a How It's Made episode about mayonnaise in 2011.
When Eugenia Duke was 18, she married Harry Cuthbert Duke in 1900 and moved to Greenville. She was active in working towards passage of the Nineteenth Amendment to the United States Constitution granting women the right to vote.[15]
After the sale of the company, Eugenia Duke followed Martha, her only child, to California and opened the Duchess Sandwich Company as well as the Duchess Catering Company.[5][16]
