Frederick Clark Sayles (July 17, 1835 – June 5, 1903) was an American entrepreneur and the first mayor of Pawtucket, Rhode Island in 1885.[1]
He began working in his brother's Sayles Bleacheries in 1853, and eventually became a partner in the business.[2] Saylesville, Rhode Island is named for his family. He bought the Hearthside farm in Lincoln, Rhode Island in 1901. At this property, he raised prized Broodmare horses.[1]
He was very involved in the Central Congregational Church in Providence, Rhode Island.
He married Debra Cook Wilcox and had three children.[3] After the death of his wife, Sayles donated a plot of land for the construction of a public library in Pawtucket. The Deborah Cook Sayles Public Library opened in 1902 and is on the National Register of Historic Places.[4] His daughter, Deborah Wilcox Hill and her husband Fred B Hill, contributed to the construction of the Sayles-Hill men's gymnasium (later turned student center) at Carleton College in Northfield, Minnesota, named in Sayles' honor in 1910.[5] His other daughter, Caroline M. Sayles, married Frederick William Holls, a lawyer and diplomat who served as the Secretary of the United States Delegation to the Hague Conventions of 1899 and 1907.[6]
