Next week, Sotheby's in Paris will auction the collection of Fred Feinsilber, according to the International Herald-Tribune. Retired chemical engineering magnate and Holocaust refugee Feinsilber has been collecting fine editions of 19th and 20th century "avant-garde" literature and their early predecessors (back to the Renaissance), as well as foundational architecture texts and key texts in the history of science.
When asked why he's decided to sell the collection, Feinsilber said "When you collect, you first buy what overwhelms you. Then you learn to rise to its level. When the discovery process is over, collecting turns into a power game. It is time to move on."
