Bruce C. Wenner was born in Milford, PA, the son of Dr. E. Bruce Wenner and Jennie Blanche (Wolfe) Wenner. He graduated from Central High School in Philadelphia and then gained his B.S. in Architecture from the University of Pennsylvania in 1916, receiving the faculty medal. Even before graduation, Wenner had found employment with Baily & Bassett, but with the intervention of World War I, Wenner journeyed to France, where he "had charge of designing A.E.F. cemeteries" from 1917 to 1919, according to his application for membership in the Philadelphia Chapter of the AIA. After his return, he gained further knowledge regarding reinforced concrete by attending the Drexel Institute in 1920-1921 while he was employed by engineer William H. Timm, for whom he worked from 1920-1926. However, like his partner Thoralf M. Sundt, Wenner is cited as one of the leading architects in the Philadelphia office of the Methodist Episcopal Church's Bureau of Architecture in 1926; therefore, it is speculated that sometime during 1925/26 Wenner moved over to the Bureau. By 1930 independent projects appear in the Philadelphia Real Estate Record and Builders Guide for Sundt & Wenner, and this partnership will continue through 1935. In 1936 A. Hensel Fink enters the partnership, changing the name to Sundt, Wenner & Fink in PRERBG references. However, again according to Wenner's membership application, by 1936 Wenner & Fink were undertaking some projects independent of Thoralf M. Sundt. In the Philadelphia city telephone directories for the 1940s Wenner & Fink continue through 1947, and but there also appears Wenner & Chance, with offices in the Architects Building until Wenner's death in 1947.

Wenner held memberships in the American Institute of Architects and in the T-Square Club. He also served as the chair of the Department of Architecture for the Drexel Institute Evening School.
