Peter Dudley (21st June, 1935 - 20th October, 1983) was a British actor who played several different roles on Coronation Street: firstly a waiter in 1967, then a delivery man in 1968, Dougie Bowker in 1973, jeweller Donald Anderson in 1978, then, most famously, as Bert Tilsley from 1979 till shortly before his death in 1983. Peter's stint on the programme was fraught with controversy when in the early 1980s he pleaded guilty in court to attempting to pick up men in a public toilet (known as importuning.) Producer Bill Podmore and Granada stood by him and he was let off with a £200 fine, but he was charged a few months later with the same offence. This time he denied the charge, claiming he had been set up by the police, and chose to be tried in Crown Court even though it would generate considerable publicity. The judge in the case ordered a retrial after the jury was unable to reach a verdict.

Dudley suffered a stroke and lost the use of his left arm and a storyline was written to explain why Bert Tilsley's arm did not function properly. In 1983, Bert was written out of the show to allow Dudley to prepare for his retrial, but suffered two heart attacks and a stroke and died before it could take place.

Peter's other television credits include The Dustbinmen and Crown Court.
