At 48, photographer and writer Bill Hayes moved to New York City, determined to change his life after the death of his partner. A lifelong insomniac, he became captivated by his new world, wandering the streets at night with his camera. He also fell in love with his neighbour, Oliver Sacks. In this podcast, Bill talks to Stephen Metcalf about Insomniac City: New York, Oliver, and Me, his loving tribute to Sacks and to New York, and his tender insights into living with both.
