Sir David Frost (1939–2013) was an English journalist, comedian, and television host. Known for his history-making interviews with top political figures, Frost was the only person to have interviewed the eight British prime ministers serving between 1964 and 2010 and the seven United States presidents in office between 1969 and 2009. He was also the last person to interview Mohammad Reza Pahlavi, the last shah of Iran. Frost was the author of several books, including his autobiography. His famous interviews with Richard Nixon formed the basis for the Oscar-nominated film Frost/Nixon.
