Christopher Paul Greener (21 November 1943 – 11 February 2015)[1] was a British actor and basketball player who went on to represent the United Kingdom.

From a very young age, Greener had a tumour at the base of his pituitary gland, which controls the release of human growth hormone.

He received treatment upon diagnosis, but because radiation therapy requires time to take effect, he grew another inch in the following year(s), reaching 7 ft 6+1⁄4 in (229.2 cm).

In the late 1960s and early 1970s, Greener was an international basketball player for the Great Britain team and was often at the Crystal Palace National Sports Centre.

He appeared in several documentaries chronicling the lives of the very tall, including the World's Tallest People television special on The Learning Channel in the United States and Superhuman: Giants on the UK's ITV.
