Liz Gebhardt (12 April 1945 – 10 August 1996) was an English actress, best known for playing the part of form 5C pupil Maureen Bullock in the LWT sitcom Please Sir! and in the subsequent spin-off show, The Fenn Street Gang (1971–73). Following on from her role in the show and its spin-off, she continued working in television, starring in a number of supporting roles in programmes such as New Scotland Yard, Z-Cars, The Naked Civil Servant, Grange Hill, The Bill, Keeping Up Appearances and others. Her few film roles included the movie version of Please Sir! (1971), and a brief appearance as a maid in Julius Caesar (1970). In her earlier years, Liz attended Willesden County Grammar School in North-West London. Gebhardt was diagnosed with cancer and admitted to hospital in summer 1996; she died in August, aged 51. During her cancer treatment, she sustained injuries from radiotherapy, a situation which contributed to the formation of a campaign to prevent damage from such treatment. Gebhardt was married to fellow actor and former director of the Regent’s Park Open Air Theatre, Ian Talbot.
