Analysis of information sources in references of the Wikipedia article "Mayor Gallery" in English language version.
At his death, Flechtheim left his gallery records and personal library (now destroyed) with Fred Mayor, founder of Mayor Gallery.
Alfred Flechtheim's hope was to relocate to Paris or New York with Daniel-Henry Kahnweiler or Paul Rosenberg but in December 1933 he moved to London and worked with the Mayor Gallery. From 1934 he represented Kahnweiler's Galerie Simon in London and desperately went back and forth to Paris to make a living. In London he organized exhibitions of works by Picasso, Gris, Léger and Marie Laurencin and up until 1936 he managed to enter and leave Nazi Germany on several occasions at great personal risk to see his wife Betty who has stayed in Berlin because she was unable to pay Jewish 'flight tax.'
