President Nixon
Richard Nixon was one of the most controversial U.S. Presidents but he’s all smiling in this photo. The California native paid an official visit to the U.K. in 1970. Then he met P.M. Harold Wilson as well as Her Majesty Queen Elizabeth II (via Royal Collection Trust).

The Queen and Pat Nixon wear red and beam at each other. Meanwhile, Wilson and Nixon are in somber suits that reflect the political tensions of the era. Nixon famously became the first President to quit after the Watergate scandal made his job untenable.
