Devian Kruck is the UK Representative of David Feldman SA International Auctioneers & Curator at the Museum of Philately. In April 2020 Devian set up a series of philatelic biographies on the blog of the DFSA website and presented Georges Herpin as Legendary Collector #1. The series was gradually built up by the biographies of legends like Frederick Philbrick, Philip Ferrari de La Renotière, Thomas Keay Tapling, William E. Image, William Westoby and many more. A few days ago the stage was set for Alphonse Mayer von Rothschild as Legendary Collector #31. At the end of each philatelic biography, published on the David Feldman website, there are links to all Devlan’s earlier pieces.
