Hoffman, a noted Dallas philanthropist, died Sunday at an area hospital. He had been suffering from leukemia since December, according to his family.

He was a co-founder and managing editor of the humorous National Lampoon, spawned from the Harvard Lampoon, created while he was a student at the university.

Hoffman was named one of Business Week magazine's top 50 philanthropists for 2005.

A longtime art collector, he and his wife, Marguerite, in March gave 224 art objects valued at $150 million to the Dallas Museum of Art.
