David Boyd contributed more to Philadelphia's architectural legacy than just his designs. Throughout his life he remained an active member in a variety of professional organizations including the T-Square Club, as Treasurer from 1893-95 and President from 1896-1897. Boyd became a member of AIA in 1897 and was awarded fellowship status in 1908. He also served as Secretary for the National AIA in 1914 and Vice-President in 1915. Also in 1915, Boyd was hired by the Narbreth Civic Association to serve as their general consulting architect. All houses constructed were subject to his individual approval. Boyd was active as part of the Philadelphia Fire Commission and the Housing Corporation of the U.S. department of Labor. In 1920 Boyd was asked to consult in the commission preparing the building code for the State of Pennsylvania Housing Association. Boyd remained an active contributor to many clubs and organizations over the course of his life and career. Although his early career was limited to residential work, Boyd ultimately had a great impact on architectural practice in Philadelphia and especially in its surrounding areas. David Knickerbacker Boyd never retired. He collapsed in his Philadelphia studio in February of 1944 at the age of 72.
