Houses in the 700 block of C Street SE, since demolished

Hans Wunderlich, a soloist with the Marine Band, is shown with his dog on the steps of his family home at 718 C Street SE. He and Mrs. Wunderlich moved into their home when the row of houses was first built. Mrs. Wunderlich lived there until she died, shortly before the block was demolished to make way for a new playground for Hine Junior High School around 1964. When this photograph was taken,Towers School stood across C Street from the houses.
