Heathrow worked closely with King's College history professor Dominic Sandbrook to shortlist the most famous departures before the public voted for their winners.
Mr Sandbrook said the public's choices reflected Britain's "historic strengths", adding: "Britain has always been a land of explorers and entertainers, inventors and innovators.
"I think the public's choices also reflect our historic strengths in everything from philanthropy and popular culture to science and technology. It's a valuable reminder that we're at our best when we face outwards, as a nation of international ambitions and global horizons."
Heathrow's Development Director John Holland-Kaye said the list of departures demonstrated "how important it is to have a world class hub directly connecting the UK to future international success".
