William C. Brocklesby

William C. Brocklesby (1847-1910) was an American architect practicing in Hartford, Connecticut.

William Claiborne Brocklesby was born May 28, 1847, in Hartford, Connecticut. He attended the public schools of Hartford before entering Trinity College, where his father, John Brocklesby, was a professor. After his graduation in 1869, he studied in the office of New York architect Richard Upjohn. In 1878, he established his own practice in Hartford. He practiced alone until 1904, when he established a partnership with H. Hilliard Smith, an employee of several years. Brocklesby & Smith was active until Brocklesby's death in late 1910. The following year, Smith would reorganize the office as Smith & Bassette.

Brocklesby was elected an associate of the American Institute of Architects in 1901. He died in Hartford on October 9, 1910.

Brocklesby was married in 1876 to Grace C. Stuart of Wethersfield, Connecticut.

Several of Brocklesby's works have been individually listed on the United States National Register of Historic Places, and others contribute to listed historic districts. In addition to his projects in and around Hartford, Brocklesby built extensively on the campus of Smith College in Northampton, Massachusetts and on others in Massachusetts.
