William H. Sliker (1872-1951) was a photographer based in Northeast Philadelphia, Pennsylvania in the early 20th century. Sliker and his son, Charles L. Sliker (1892-1968), traveled periodically throughout various Northeast Philadelphia neighborhoods photographing scenery, events, buildings, people, and other subjects. The William H. Sliker glass plate negatives, circa 1905-1937, consist of over three hundred glass plate negatives. Almost every glass plate negative has a corresponding modern paper print. The images primarily depict the Northeast Philadelphia neighborhoods of Bridesburg, Bustleton, Fox Chase, Frankford, Somerton, Tacony, Torresdale, and Wissinoming, but other locations are also shown.
