Jack Anderson, whose investigative column once appeared in more than 1,000 newspapers with 40 million readers, won a Pulitzer Prize and prompted J. Edgar Hoover to call him "lower than the regurgitated filth of vultures," died yesterday. He was 83.

The cause was Parkinson's disease, Mr. Anderson's daughter Laurie Anderson-Bruch told The Associated Press.

Mr. Anderson was a flamboyant bridge between the muckrakers of the early decades of the 20th century and the battalions of investigative reporters unleashed by news organizations after Watergate. He relished being called "the Paul Revere of journalism" for his knack for uncovering major stories first almost as much as he enjoyed being at the top of President Richard M. Nixon's enemies list.

His journalistic reach extended to radio, television and magazines, and his scoops were legion. They included the United States' tilt away from India toward Pakistan during Bangladesh's war for independence, which won the Pulitzer Prize for national reporting in 1972.
