One by One is a British television series made by the BBC between 29 January 1984 and 2 May 1987.^{[citation needed]}

The series, created by Anthony Read,^[1] was based on the early life and writings of international veterinary surgeon David Taylor.^[2] Called Donald Turner in the series, the show follows his work caring for exotic animals at zoos in Britain, from the 1950s to the 1970s. Each series was set during a different decade, with exteriors filmed at Dudley Zoo, Chester Zoo and Knowsley Safari Park.

Thirty-two episodes were made over three series, transmitted on BBC1 in the early parts of 1984, 1985 & 1987. BBC1 repeated series 2 during the early months of 1986, as no new series had been made that year. The third series was also repeated on BBC1 over the Spring & Summer of 1988.
