Truman and Picasso were contemporaries and were both shaped by and shapers of the great events of the twentieth century - the man who painted Guernica and the man who authorised the use of atomic bombs against civilians.But in most ways, they couldn’t have been more different. Picasso was a communist, and probably the only thing Harry Truman hated more than communists was modern art. Picasso was an indifferent father, a womaniser, and a millionaire. Truman was utterly devoted to his family and, despite his fame, far from a rich man. How did they come to be shaking hands in front of Picasso’s studio in the South of France? Truman’s meeting with Picasso was quietly arranged by Alfred H. Barr Jr, the founding director of New York’s Museum of Modern Art and an early champion of Picasso. Barr knew that if he could convince these two ideological antipodes, the straight-talking politician from Missouri and the Cubist painter from Malaga, to simply shake hands, it would send a powerful message, not just to reactionary Republicans pushing McCarthyism at home, but to the whole world: modern art was not evil. Truman author Matthew Algeo retraced the Trumans’ Mediterranean vacation and visited the places they went with Picasso, including Picasso’s villa, Picasso’s ceramics studio in Vallauris, and Chateau Grimaldi, a museum in Antibes. A rigorous history with a heartwarming centre, When Harry Met Pablo intertwines the biographies of Truman and Picasso, the history of modern art, and twentieth century American politics, but at its core it is the touching story of two old men who meet for the first time and realise they have more in common - and are more alike - than they ever imagined.
