John Rochester Thomas, the Architect

ThomasJohnRochesterPortraitLROne of the most prolific architects in the late nineteenth century John Rochester Thomas was born in Rochester, NY on June 18 of 1848. He was the son of William and Elizabeth Thomas. John was enrolled in the Rochester Public School system until early 1862. At that time he dropped out to help his family after his father's business failed. Later that year, John apprenticed under the Rochester architect, Merwin Austin. He also took classes at the University of Rochester. After coming back from studying the grand buildings of Europe, John Thomas entered professional practice in 1868 at the age of 20.

Among his work are three buildings in Fairport. Three of his structures have been locally designated and are on the National Register of Historic Places. They are the First Congregational United Church of Christ at 26 East Church Street, the Henry DeLand House at 1 East Church Street, and the First Baptist Church of Fairport located at 92 South Main Street.  Several homes in Fairport were also designed by Mr. Thomas. They are the Charles H. Howe House at 26 Perrin Street, 113 West Church Street and 176 North Main Street.

ThomasJ.R.SibleyHallHistMonroeCty1877LRJohn's designs were not only a pleasure to look at, but they also incorporated innovative ideas into his work as well . In his Sibley Hall (circa 1877) design on the University of Rochester campus, John incorporated steel beams and iron staircases into the stone structure to make it the first fireproof building in Rochester.

Thomas was the first to introduce the mansard roof in residential buildings in Rochester. Previously, this roof style was only used for large edifices and public buildings. His finest example of this type of design can be seen today adorning the Green Lantern Inn, circa 1875 - 1876 at 1 East Church Street.

In designing the First Baptist Church of Fairport, Thomas included an entrance to the church, parts of which can be slid back to allow exit in an emergency. This concept was developed because of a gruesome fire in a Rochester church where several people were trampled to death in a panic when a fire was discovered in the nave of the church.

In 1874, John was still working in Rochester at 53-55 Reynolds Arcade and was appointed state architect by then New York State Governor Dix. Through this appointment, he designed the State Reformatory at Elmira, which was considered a model of prison design at the time (drawings of which are in the collections of the Rochester Historical Society). John married Julia Hortense in Rochester in 1877. They had 4 daughters and a son together. Five years later in 1882 the family moved to New York City.

Perrin 26 v2Web400From his office on Broadway, John R. Thomas designed over 100 churches, numerous state prisons and public buildings in New York City and along the east coast of the United States. He was known as a leader in prison and church design. In 1891 he read a paper on "Church Architecture" before the conference of clergymen in Boston and in 1893 he appeared before the National Prison Association in Pittsburgh, PA to read another paper on the "History of Prison Architecture." Mr. Thomas was a member of the New York Chamber of Commerce, New York Yacht Club, the Sculpture Society, National Arts Club, Architecture League and was on the executive committee of the New York Prison Association.
