Longtime British actor Mark Eden passed away January 1 at the age of 92 after a battle with Alzheimer’s, his agent has confirmed.

The actor – who was best known for playing TV villain Alan Bradley in Coronation Street from 1986 to 1989 – leaves behind his wife Sue Nicholls, 77, who still plays Audrey Roberts in the ITV soap.

He appeared for eight years in Corrie leaving after his character was killed by a tram in Blackpool, in one of the most memorable scenes in Coronation Street history. The episode was watched by 21.4 million viewers. Eden later unveiled a plaque at the tram stop where the scene was filmed.

Eden is also known to cult TV fans for playing title character in the 1964 Doctor Who story “Marco Polo”. The seven-part story, completely missing from the BBC archives, was the first in which the Doctor met a famous figure from history. The character of Marco Polo, the famous Venician explorer, narrated the story which saw the TARDIS crew join the caravan of the adventurer as it travelled through the Gobi desert to Cathay and the court of Kublai Khan.

Mark Eden had a career of over 50 years in British Television with his first credited role in 1958 in the sci-fi serieal, Quatermass And The Pit. He appeared in the 1965 film Doctor Zhivago, as well as the TV show The Avengers. In The Prisoner he played Number 100 and had a role in The Newcomers. Other roles included parts in Z-Cars, Clouds of Witness, Murder Must Advertise, The Top Secret Life of Edgar Briggs, London Belongs to Me, Poldark, The Detective and Crown Court.

Eden had been living with Alzheimer’s disease ‘for some time’, and was hospitalised in November.
