Erdman, John
From David Wojnarowicz Knowledge Base
With his partner Gary Schneider, Erdman runs Schneider-Erdman Inc, a photography lab in New York City, which they opened at the urging of Peter Hujar in 1981. Hujar and Wojnarowicz both printed photography exclusively at their lab. Schneider-Erdman also printed photos for Nan Goldin, Richard Avedon, Matthew Barney, and many others. A collection of their prints is archived at Harvard as the "Schneider Erdman Printer’s Proof Collection."
Erdman also played the role of the father in Wojnarowicz's film Where Evil Dwells, which he made with Tommy Turner. He was previously a performer with choreographers such as Yvonne Rainer and Robert Wilson.
