to the west and Oxford Avenue to the east, its northernmost point being Sanger Street, just below the intersection of Castor Avenue, Roosevelt Blvd (U.S. 1) and Oxford Avenue. However, a more broad definition of Northwood would extend to Adams Avenue on the south, including the location of Northwood Park and the larger mansions on Castor Avenue south of Harrison Street. Three of Frankford's schools lie within Northwood. Other facilities in Northwood include Frankford High School's War Memorial Stadium, built in honor of area residents who served in World War I, and Baldwin Field, named for local businessman and philanthropist E. A. Baldwin, who had a milk business in Northwood. The field was dedicated on June 3, 1938. The neighborhood is home to a mostly middle-class population. The neighborhood was also home to former Philadelphia mayor and Representative from the 5th (then 3rd) Congressional District William J. Green, III, and the late Edward R. Becker, former justice on the Third Circuit Court of Appeals for the United States. Burk Deed Restriction In 1881, Alfred and Louis Burk founded Louis Burk, Inc., Philadelphia meat packers, and also built Atlantic City's original Steel Pier in 1898. Several other brothers were engaged in this family-run business. (Another brother, Henry Burk, was a well-known local politician.) As real-estate investors and developers in Philadelphia, they bought and sold large parcels of land in Northwood. To protect the integrity of the neighborhood, Louis Burk placed several various deed restrictions upon many of the tracts he sold. One variant form: BURK DEED RESTRICTION, AS TO THE 900 BLOCK OF HERBERT STREET – RESTRICTIONS as in Deed Book J.M.H. 317 page 63 UNDER AND SUBJECT nevertheless that no bldg. shall be erected or built or permitted to be erected or built upon any of the hereby granted tract of land or any part thereof except for the use as a private dwelling or a private garage in connection with a dwelling nor shall any bldg. thereon erected be converted or used for any other purpose that there shall be wooden division fences between subdivision of the hereby granted tracts of land that divisions may be made by an iron fence not to exceed 4' in height or a suitable hedge not to exceed that height and that no dwelling shall be erected which shall cost less than $2500 to construct that no garage shall be built within 75'
