The earliest photograph of Glover Park; the photographer would have been standing in what is now the 3800 block of Calvert Street, NW, looking south toward Georgetown. Holy Rood Cemetery is at the upper left, separated by a sunlit fence from Tunlaw Road. The cedars on the horizon mark the present site of Duke Ellington High School. The soldiers are in the U.S. Signal Corps, founded here in 1861. (Photo: Miller’s Photographic History of the Civil War (1911), Vol. 8, p.306)
