Senneff, George



Senneff, George


George Senneff was a carpenter who first appeared in Philadelphia city directories in 1830 at 100 South Twelfth Street; he remained at that address throughout most of his life. In 1831 Senneff attempted to make the transition from carpenter to architect when he entered the competition for Wills Hospital for the Relief of the Indigent Blind and Lame. In that competition he faced John C. Trautwine, William Rodrigue, John Haviland, and Thomas Ustick Walter, all well-known professionals. Thomas Ustick Walter won the competition, and the building, now demolished, was erected on Logan Square and Race Street between 18th and 19th Streets (1833-33; altered, 1867 and 1909). However, Senneff did win a respectable third prize ($25) (as did Rodrigue and and Haviland) and soon was approached by the new Board of Managers for Haverford College, who sought a designer for Founders Hall. Although Senneff provided the plans and exterior appearance, he was paid only a modest sum for that effort; and other builders were paid to modify and construct the building. After this disappointment Senneff returned to carpentry.
