Alfred Flechtheim (April 1, 1878 in Münster, Westphalia, † March 9, 1937 in London) was a German art dealer, art collector, journalist and publisher.
Early Years 
Flechtheim was born into a Jewish merchant family; his father, Emil Flechtheim, was a grain dealer. Alfred became a partner in his father's company after business internships in London and Paris.
Art Dealer 
Flechtheim appeared in the art world shortly after 1900, with a collection of paintings by Vincent van Gogh und Paul Cézanne; French Avant garde early works of Pablo Picasso, Georges Braque and Andre Derain; paintings of Wassily Kandinsky, Maurice de Vlaminck, Alexej von Jawlensky, Gabriele Münter, and the Rhein Expressionists Heinrich Campendonk, August Macke, Heinrich Nauen, and Paul Adolf Seehaus. Flechtheim opened his first gallery in Düsseldorf in 1913, followed by galleries in Berlin, Frankfurt, Cologne, and Vienna.
Later career 
Flechtheim served in the German Army during World War I, but not at the front. His art business collapsed during the war but he re-opened in Düsseldorf in 1919. In 1921 he founded Der Querschnitt (the Cross Section), a cultural magazine. Legendary, glamorous parties in Flechtheim's gallery overflowed with the glitterati of the new Berlin: movie stars, titans of finance, prizefighters and artists of every stripe.
Flechtheim and the Nazis 
As Hitler rose to power in the late 1920s and early 1930s, Flechtheim became a bête noire because of the art he espoused and championed. In 1933, Sturmabteilung men broke up an auction of Flechtheim's paintings. The Nazis aryanized Flechtheim's gallery, as they would many other Jewish businesses, and turned it over to Flechtheim's business manager, Alex Vömel. After the war, former party member Vömel said he didn't even remember who Flechtheim was. The Nazis seized and sold off Flechtheim's private collection, as well as the contents of his gallery.
Emigration and Death 
Six months after the Nazis came to power in 1933, Flechtheim, penniless, fled to Paris, and tried to find work with his former business partner, Daniel-Henry Kahnweiler. Flechtheim subsequently organized exhibits in London of the paintings of exiled German artists. In London, Flechtheim slipped on a patch of ice, was taken to a hospital, punctured his leg on a rusty nail in his hospital bed, developed septicemia leading to amputation of his leg, and died.
Personal life 
Flechtheim married Betty Goldschmidt, a wealthy Dortmund merchant's daughter. On a honeymoon trip to Paris, Flechtheim invested Betty's dowry in cubist art, to the horror of his inlaws. The marriage was childless. Betty Flechtheim was with her husband in London during his final days. Then she returned to Berlin. In 1941, when she was ordered to report for deportation to Minsk, she ingested a lethal dose of Veronal. The Gestapo seized her art collection.
