One of the most significant 20th-century photographers, Frank revolutionised documentary photography, and played a considerable part in the U.S. independent scene. Evans regarded him as his protégé, played a huge part in getting him a Guggenheim grant to travel the country, and became a close friend. Frank stayed in Segal’s basement, collaborated with Kerouac (met on the sidewalk outside a party) and Leslie (though they fell out over credits), and explained to Jagger that he found Richards more interesting. Ginsberg was a lifelong friend. Eugene Smith, who knew him, called him the Franz Kafka of photography.
