“Robert Rauschenberg, the irrepressibly prolific American artist who time and again reshaped art in the 20th century, died Monday night. […] A painter, photographer, printmaker, choreographer, onstage performer, set designer and, in later years, even a composer, Mr. Rauschenberg defied the traditional idea that an artist stick to one medium or style. He pushed, prodded and sometimes reconceived all the mediums in which he worked.” - obituary
