William H. Green (1875-1959) was a clerk for the Philadelphia Water Department in Philadelphia, Pennsylvania with a strong interest in photography. The William H. Green glass plate negatives, circa 1908-1910, 1990-1991, consist of approximately 110 glass plate negatives, half plates and quarter plates, taken by William Green that mostly depict images of Northeast Philadelphia such as Frankford and Bustleton but also include images from other areas of Philadelphia and nearby locations including Olney, Valley Forge, and elsewhere.
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.
