As documented in the book Ana Mendieta: A Book of Works, edited by Bonnie Clearwater, before her death, Mendieta was working on a series of photo-etchings of cave sculptures she had created at Escaleras de Jaruco, Jaruco State Park in Havana, Cuba.
Alphonse Poitevin (Conflans-sur-Anille, 1819 – Conflans-sur-Anille, 1882) was a French chemist, photographer and civil engineer who discovered the light–sensitive properties of bichromated gelatin and invented both the photolithography and collotype processes.
