Donald Baverstock was the Controller of BBC One who ordered Sydney Newman to create the Saturday tea time show that became Doctor Who. He was significantly involved in the creation of the programme.

A caricature of him, called "Mr Borusa", was played by Mark Gatiss in The Pitch of Fear, a broad fictionalisation of Newman's pitch meeting for Doctor Who.
