If there is one collection I have to mention, being important for all Impressionist and Neoimpressionist lovers around the world, it most certainly is the Berggruen collection. Literally every important artist from these periods is present within this impressive collection. No just one work of art but multiple makes this collection as important as many of the collections that were formed with tax money, and gifts over the centuries. This collection was formed over a period of Seventy years and holds over 165 masterpieces .
Berggruen started to collect in 1939 after he fled Germany in 1936 and managed to obtain only the very best and in most cases extremely rare and highly collectable works of art. The collection was made a gift to Germany and is now housed in the Berggruen Museum in Berlin, but before it had a place of its own, it travelled the world and many have had the occasion to see for themselves the beauty of this impressive collection. http://www.ftn-books.com has now the catalogue for the Geneva location available. The exhibition was held in Geneva at the ~Musee d’Art et d’Histoire in 1988.
