Color glass plate (Lippmann process)
Musée de l'Elysée
© Gabriel Lippmann
The Musée de l'Elysée gives the date of this image as around 1892 but William R. Alschuler (pers. comm. 30 December 2009) pointed out that this image shows Lippmann when he was sick and elderly and he died in 1921. Based on this the date is most likely 1918-1921.
