Photographer Li Zhensheng who used a Rolleiflex TLR (and other cameras) has passed away at age 79 in June 2020. He is famous for his photographic account of the tumult during Cultural Revolution in China. Photographers were ordered to hand in their photos of Cultural Revolution after Mao died in 1976. It was dangerous for him to hide the 20,000 negatives that recorded the excesses and cruelty. He risked his life hiding them. His photographs of this period in China history are rare. Otherwise there is no photographic record. His friend Li Mingda to whom he entrusted the secret hiding place of the photos, never betrayed him - at a time during Cultural Revolution when it is not uncommon for children to betray their parents.
