At 18, he started studying commercial drawing in Pittsburgh and then continued his education at the Visual Arts of New York. He tried different techniques like collage, painting, installation or video. Inspired by street art, Haring started drawing with white chalk on black metro billboards in New York. He also engraved sandstone slabs on sidewalks in East Village (they are still visible today!). His artwork is a permanent story of toddlers, dolphins, TV sets, barking dogs, flying saucers, pyramids, ringing alarm clocks but also of sexuality and death wishes. In 1988, he is diagnosed with AIDS. Therefore, he strongly committed himself in the fight against this disease. To do so, he founded the Keith Haring Foundation in 1989. He died from AIDS at 31.
