William R. "Bill" Sullivan (September 10, 1942 – October 23, 2010) was an American painter, printmaker and publisher.
Sullivan was born in New Haven, Connecticut, and died in Albany, New York. He attended Silvermine College and earned an M.F.A. from The University of Pennsylvania, where he studied with Fairfield Porter, Neil Welliver, Jane Freilicher, John Button and Rudy Burckhardt. He also studied privately with Josef and Annie Albers.
In 1957, when he was 15 years old, Sullivan was spending a summer washing dishes in Lenox, Massachusetts, and met Claes Oldenburg, who was there working at a resort and running a small gallery in a barn. Oldenburg's early paintings became an inspiration for Sullivan. That fall he followed Oldenburg and his wife back to New York City, where he slept on Oldenburg's couch and camped out in Central Park. He worked as a night dishwasher at Café Figaro which, along with the San Remo Bar across the street, was a place where writers and artists congregated. Oldenburg included Sullivan's work in group shows at Judson Gallery, which he was running. Besides Oldenburg the show included Jim Dine and Red Grooms, who were unknown artists at the time.
In the late 1960s, Sullivan joined Bowery Gallery, an artist-run gallery in a storefront on Bowery that was dedicated mostly to figurative art, where he was one of the first artists to show. Later, when the Alliance of Figurative Artists was starting, Sullivan organized weekly panels and discussions at The Educational Alliance. He organized these panels on a regular basis for several years.
Sullivan's first solo show at Bowery Gallery in 1970 included paintings depicting people, New York cityscapes and still lifes. After this show, Sullivan developed an interest in landscape painting. The city of New York became one of his favorite subjects. New York City, the Hudson River and Manhattan's West Side highway became his main subjects. He had several shows of these paintings at Bowery Gallery and continued to paint the Hudson till the end of his life. At one of these shows he met art collector G. W. Einstein, who became his friend and represented him for many years. Sullivan had his first solo show at G. W. Einstein Company in 1978.
