Rothbard died of a heart attack on January 7, 1995, at the age of 68. He was buried in Oakwood Cemetery, Unionville, Virginia.
After Rothbard's death in 1995, Lew Rockwell, president of the Mises Institute, told The New York Times that Rothbard was "the founder of right-wing anarchism". William F. Buckley Jr. wrote a critical obituary in the National Review, criticizing Rothbard's "defective judgment" and views on the Cold War. The Mises Institute published Murray N. Rothbard, In Memoriam which included memorials from 31 individuals, including libertarians and academics. Journalist Brian Doherty has summarized Buckley's obituary as follows: "[W]hen Rothbard died in 1995, his old pal William Buckley took pen in hand to piss on his grave". Hoppe, Rockwell, and Rothbard's colleagues at the Mises Institute took a different view, arguing that he was one of the most important philosophers in history.
