Brian Cobby
Brian Cobby was an English actor and telephone exchange worker who, in 1985, became the first male voice of the British speaking clock.
Cobby was born in Gravesend, Kent, the son of Amy and Sydney Cobby, a retail manager. Sydney had hoped to serve in the Royal Navy like his father and grandfather before him, but was unable to join due to a ruptured eardrum. He instead joined Woolworths and moved around the country managing its stores, finally transferring from Gravesend to Oxford, where Brian spent most of his early years.
