Grounds of the château of Captain René-François Fenwick, Senlis, France, December 26, 1914, by Auguste Léon, via Archives of the Planet Collection – Albert Kahn Museum /Département des Hauts-de-Seine.
The house itself had been largely destroyed in a WWI battle about four months before the photo was taken (another image here). Fenwick was a captain of the 31st Regiment of the Dragons who fell in combat in July 1918 (“an example of energy and good humor under fire”).
The autochrome above is one of about seventy-two thousand that were commissioned and then archived by Albert Kahn, a wealthy French banker, between 1909 and 1931. Kahn sent thirteen photographers and filmmakers to fifty countries “to fix, once and for all, aspects, practices, and modes of human activity whose fatal disappearance is no longer ‘a matter of time.'”* The resulting collection is called Archives de la Planète and now resides in its own museum at Kahn’s old suburban estate at Boulogne-Billancourt, just west of Paris. Since June 2016, the archive has also been available for viewing online here.
