Henri Gabriel Marceau (12 June 1896, in Richmond, Virginia – 15 September 1969, in Philadelphia, Pennsylvania) was an American architect, teacher, art historian and museum curator.
He studied architecture at Columbia University, but his education was interrupted by military service in World War I.
Philadelphia's fire marshall subsequently found Johnson's mansion at 510 South Broad Street not to be fireproof, and the 275 works exhibited there were "temporarily" transferred to PMA in June 1933.
[6] He curated exhibitions on a wide range of artists, including Thomas Eakins, William Rush, Benjamin West, Cezanne, Corot, and others.
[7] Marceau wrote numerous articles for the Philadelphia Museum of Art Bulletin and other PMA publications.
