Wilson Brothers

Wilson Brothers & Company was a prominent Victorian-era architecture and engineering firm established in Philadelphia, Pennsylvania, that was especially noted for its structural expertise. The brothers designed or contributed engineering work to hundreds of bridges, railroad stations and industrial buildings, including the principal buildings at the 1876 Centennial Exposition. They also designed churches, hospitals, schools, hotels and private residences. Among their surviving major works are the Pennsylvania Railroad, Connecting Railway Bridge over the Schuylkill River (1866–67), the main building of Drexel University (1888–91), and the train shed of Reading Terminal (1891–93), all in Philadelphia.

The firm's founders were Joseph Miller Wilson (1838–1902), architect and civil engineer, John Allston Wilson (1837–96), civil engineer, and Frederick Godfrey Thorn (c. 1837–1911), architect and civil engineer. Youngest brother Henry W. Wilson (1844–1910), civil engineer, joined the firm in 1886, and was promoted to partner in 1899. All three Wilson brothers attended Rensselaer Polytechnic Institute in Troy, NY. Joseph also studied metallurgy at the University of Pennsylvania.

Joseph worked in the construction department of the Pennsylvania Railroad (PRR) from 1860 to 1876, designing bridges and railroad structures, including several commuter stations on the Main Line. For a PRR subsidiary, he designed the Baltimore & Potomac Railroad Passenger Terminal in Washington, DC (1873–77, demolished 1908), the station in which U.S. President James A. Garfield was assassinated in 1881. The National Gallery of Art now occupies its site at 6th Street & Constitution Avenue on the National Mall. John did engineering work for several railroads, including the PRR and the Reading Railroad. Wilson Brothers & Company was founded on January 1, 1876.
