German artist Gerhard Richter is a pre-eminent post-war visual artist, famous for his abstract as well as photorealistic paintings, in addition to his photographs and glass sculptures. He is acknowledged by many as the best living painter today. His iconic technique involves modifying original photographs by blurring certain objects or features and applying painterly brushstrokes as a revolutionary gesture that brings out the tension between different media. His works explore themes such as memory, authorship and the passing of time.
