Tina Modotti had the kind of life only the 20th century could offer--specifically, the era between the two World Wars, buoyed by the sense of possibility after the First before sinking into the vicious ideologies that caused the Second. For someone who died relatively young, Modotti had a strikingly peripatetic history--born in the squalid poverty of rural Italy, emigrating to San Francisco in time to become a minor screen actress and a photographer of note, on to post-revolutionary Mexico, Marxist Russia, Berlin and Vienna as they succumbed to fascism, Paris, where she was something of a spy, Spain during the Civil War, and then back to Mexico. She was a valued friend to a variety of great writers and artists. She was a friend to the Mexican muralists, tried to save the great Spanish poet Antonio Machado and Pablo Neruda marked her passing with a poem. She learned photography from Edward Weston and used it to document Diego Rivera's monumental murals, but her own work in that medium has a spare and meticulous power of its own, even when most political--she was a lifelong Marxist. She would have achieved much more in photography, but was deported from Mexico, winding up in a Soviet Russia with cumbersome equipment just as camera became more portable and finding herself without any photographic paper that hers could use; still, Sergei Eisenstein praised what he saw of her work. In any case, she abandoned the camera for political work, much of it undercover in France and Spain, where she passed herself off as a nun in a hospital for workers. One of her lovers was assassinated in Mexico, and a second was a Stalinist thug, famous for executions in Spain and a participant in the attack on Trotsky. The prose style of the biography sometimes breathless (though moving when describing the desperate flight of the losing Spanish Republicans from Barcelona) but well-researched (if not impeccably--the Mexican group Los Contemporaneos were poets, not artists). This biography shows that Modotti did not always live well, and certainly not without regret, but with passion and conviction wherever she found herself.
