David S. Broder, Pulitzer-Prize winning columnist and pundit whose political analysis and influence earned him the respect of the Washington press corps, has died at the age of 81.

The Washington Post announced Broder passed away Wednesday at Capital Hospice in Arlington of complications from diabetes.

Broder covered every presidential convention since 1956 and was a fixture on NBC’s “Meet the Press” since the 1960’s. He was lured away from The New York Times in August 1966 by The Washington Post’s managing editor, Benjamin C. Bradlee, who sought Broder’s help in transforming The Washington Post for a new era. Broder and The Post won the Pulitzer Prize in 1974 for coverage of the Watergate scandal. Broder worked on The Post’s national staff and wrote two columns a week for most of the past 40 years. His final column appeared on February 6.

As TIME’s James Poniewozik points out, Broder “helped create an emerging, and hugely influential, profession: the modern electronic-media pundit.” In 2008, Broder marked a milestone with his 400th appearance on “Meet the Press.”
