Aaron Siskind (December 4, 1903 – February 8, 1991) was an American photographer widely considered to be closely involved with, if not a part of, the abstract expressionist movement. In his autobiography he wrote that he began his foray into photography when he received a camera for a wedding gift and began taking pictures on his honeymoon. He quickly realised the artistic potential this offered. He worked in both New York City and Chicago.
Siskind's work focuses on the details of nature and architecture. He presents them as flat surfaces to create a new image out of them, which, he claimed, stands independent of the original subject. His work has been described as crossing the line between photography and painting.
