Britain’s Queen Elizabeth II celebrates her 94th birthday today, April 21. Born in 1926, she acceded the throne in 1952, and in 2016 she became the world’s longest-reigning current monarch. Her Majesty was photographed by Karsh on five separate occasions. See a list of those sittings. See more images from across the sittings.
