Harrold Edgar Gillingham (1864-1954) of Germantown, Pennsylvania, was a transportation executive, collector of American antiques, and a numismatist scholar noted for publishing a series of monographs on medals of merit and decorations of honor.
Treasurer of the ANS from 1867 to 1875, Levick helped found the Society's successful publications program in 1866 when he championed the effort to launch the first American numismatic journal — The American Journal of Numismatics.
John Reilly, Jr. (1876-1931) began his career as an engineer, but his love of coin collecting became his primary interest, and he would eventually amass the largest collection of Far Eastern coins in the world.
