Robert Rosenblum, an influential and irreverent art historian and museum curator known for his research on subjects ranging from Picasso to images of dogs, died on Wednesday at his home in Greenwich Village. He was 79.
He died from complications of colon cancer, said his wife, the artist Jane Kaplowitz.
For half a century, Mr. Rosenblum taught in the undergraduate and graduate art history divisions at New York University, where he occupied an endowed chair as professor of Modern European art starting in 1976. For the last decade he also served as curator of 20th-century art at the Solomon R. Guggenheim Museum. Despite his illness, diagnosed in 2004, he continued his regimen of teaching, writing and lecturing until a few weeks ago.
