Lennie Mayne was born in Sydney, Australia, his Welsh mother and Yorkshire father having emigrated there some years earlier. Initially training as an electrician, he switched to ballet dancing and choreography; then in 1953 he immigrated to London, where he successfully auditioned as a dancer for Guys and Dolls. He later moved into directing, working on many BBC series and serials in the 1960s and 1970s, including The First Lady, The Troubleshooters,Doomwatch, Warship, The Brothers, Softly, Softly: Taskforce and The Onedin Line.

He was married to the actress Frances Pidgeon, who was cast as a lady-in-waiting in The Monster of Peladon before portraying Miss Jackson in The Hand Of Fear. His own involvement with Doctor Who came through his friendship with fellow Australian Dudley Simpson, who he knew from his days in the ballet.

He was a keen fisherman (and regularly fished with friend Bernard Cribbins), and also an excellent sailor (something which he introduced and shared with fellow director Andrew Morgan): one of his favourite shows to work on was the nautical-themed The Onedin Line.

He was unfortunately lost at sea in a boating accident and presumed drowned in 1977.

Sir Ken Dodd OBE  was a British comedian and singer-songwriter, famous for his frizzy hair or "fluff dom" and buck teeth or "denchers", his favourite cleaner, the feather duster (or "tickling stick") and his greeting of "How tickled I am!", as well as his send-off "Lots and Lots of Happiness!". He works mainly in the music hall tradition, although, in the past, has occasionally appeared in drama, including as Malvolio in Shakespeare's Twelfth Night on stage in Liverpool in 1971; on television in the cameo role of 'The Tollmaster' in the 1987 Doctor Who story Delta and the Bannermen; and as Yorick (in silent flashback) in Kenneth Branagh's film version of Shakespeare's Hamlet in 1996. In the 1960s his fame was such that he rivalled The Beatles as a household name.

Dodd's stand-up comedy style is fast and relies on the rapid delivery of one-liner jokes. He has claimed that his comic influences include other Liverpool comedians like Arthur Askey, Robb Wilton, Tommy Handley and the "cheeky chappy" from Brighton Max Miller. He intersperses the comedy with occasional songs, both serious and humorous, in an incongruously fine light baritone voice.

Dodd has had many recording hits, charting on nineteen occasions in the UK Top 40, including his first single "Love Is Like a Violin" (1960), produced on Decca Records by Alex Wharton, which charted at number 8 (UK), and his song "Tears" (Columbia), which topped the UK charts for five weeks in 1965, selling over a million copies. At the time it was the UK's biggest selling single by a solo artist, and remains one of the UK's biggest selling singles of all time. Dodd was selected to perform the song on A Jubilee Of Music on BBC One on December 31, 1976, a celebration of the key pop successes of Queen Elizabeth II's first twenty-five years as UK monarch.

Dodd is renowned for the length of his performances, and during the 1960s he earned a place in the Guinness Book of Records for the world's longest ever joke-telling session: 1,500 jokes in three and a half hours (7.14 jokes per minute), undertaken at a Liverpool theatre, where audiences were observed to enter the show in shifts. More recently, Ken Dodd appeared at the Royal Variety Performance in 2006 in front of Charles, Prince of Wales and Camilla, Duchess of Cornwall, where he reprised some of his famous jokes, including those about tax accountants as well as singing his famous song "Happiness".

He was knighted in the 2017 Honours list.

The entertainer died at home in Knotty Ash on 11th March, having married his long term partner of 40 years, Anne Jones, the previous Friday.
