Stone, Carpenter & Willson was a Providence, Rhode Island based architectural firm in the late 19th and early 20th Centuries. It was named for the partners Alfred E. Stone (1834–1908),Charles E. Carpenter (1845–1923). and Edmund R. Willson (1856–1906). The firm was one of the state's most prominent.
It was established about 1885 when Willson became a full partner in the Providence architectural firm of Stone & Carpenter.
Alfred Stone was born in East Machias, Maine, in 1834. He attended the Washington Academy in that town. His family later moved to Salem, Massachusetts. After graduating high school, he began his architectural training. He worked for Towle & Foster, Shepard S. Woodcock,Washburn & Brown, and Arthur Gilman. In 1859 he began working for Providence architect Alpheus C. Morse. He studied there until the outbreak of the Civil War. He went to enlist, but a knee injury prevented him from doing so. He then worked for various business interests, also traveling in the British Isles. He opened an architural office in Providence in 1864. From 1866 to 1871 William H. Emmerton, another Salem man, was Stone's partner. Emmerton was killed in the Great Revere Train Wreck of 1871. He practiced alone until 1873, when Charles E. Carpenter became partner. This association remained unchanged for a decade, when Willson was added. Stone died December 4th, 1908 in Peterborough, New Hampshire.
Charles Edmund Carpenter was born in Pawtucket, Rhode Island on May 1st, 1845. He attended the public schools until the age of 17, when he enlisted in the Union Army. He was discharged three months later, and returned to school. He began to work under Providence civil engineer William S. Haines, learning the business. He became interested in architecture, deciding to study it instead. He entered the office of Alfred Stone in 1867, and was made a partner in 1873. He retired from the firm's affairs in 1908, after the death of Stone. He died in 1923.
