BiographyAfter Manet's death in 1883, Fernand Lochard was hired by Léon Koella Leenhoff to photograph all the works in Manet's studio as well as some works from other locations. The photographs were then inserted into four albums (of which the Morgan holds three), and the photographs were numbered 1-444 apparently based on the numbers assigned to the works by Léon Leenhoff in his manuscript register of works by Edouard Manet (original held at the Bibliothéque Nationale, France). https://www.themorgan.org/literary-historical/268655
