Deep Gratitude

It goes without saying that Mark Felt, the former FBI associate director and most famous anonymous source of all time, changed the course of American journalism. His tips to Washington Post reporter Bob Woodward about the 1972 break-in of the Democratic National Committee's Watergate headquarters, which led to the scoop of the century, put investigative journalism on a pedestal.

Felt died Friday at the age of 95, just three years after he finally revealed his identity as "Deep Throat" in a Vanity Fair magazine article. We'll remember him for his courage and adherence to civic duty.

And for being the inspiration behind the most badass scene in "All the President's Men."
