Lesley Scott

Lesley Scott received a full co-writing credit for the 1966 serial, The Ark, despite having contributed nothing to the script. The credit came at the request of writer Paul Erickson's agent, on Erickson's behalf. He wanted to share the writing credit with his then-wife. However, she did not receive any part of the copyright for the serial.
She remained the only woman credited as a writer on Doctor Who until Barbara Clegg in 1983.
