Sir Norman Joseph Wisdom, OBE (4 February 1915 – 4 October 2010) was an English actor, comedian and singer-songwriter best known for a series of comedy films produced between 1953 and 1966 featuring his hapless onscreen character that was often called Norman Pitkin. He was awarded the 1953 BAFTA Award for Most Promising Newcomer to Leading Film Roles following the release of Trouble in Store, his first film in a lead role.

Wisdom gained celebrity status in lands as far apart as South America, Iran and many Eastern Bloc countries, particularly in Albania where his films were the only ones by Western actors permitted by dictator Enver Hoxha to be shown. Charlie Chaplin once referred to Wisdom as his "favorite clown".

Wisdom later forged a career on Broadway in New York and as a television actor, winning critical acclaim for his dramatic role of a dying cancer patient in the television play Going Gently in 1981. He toured Australia and South Africa.] After the 1986 Chernobyl disaster, a hospice was named in his honour. In 1995 he was given the Freedom of the City of London and of Tirana.The same year he was appointed OBE and was knighted five years later

Wisdom first enlisted into the King's Own Royal Regiment (Lancaster), but his mother had him discharged as he was under age. He later re-enlisted as a drummer boy in the 10th Royal Hussars of the British Army. In 1930, he was posted to Lucknow, in the United Provinces of British India,as a bandsman. There he rode horses, became the flyweight boxing champion of the British Army in India and learned to play the trumpet and clarinet.

At the outbreak of the Second World War, Wisdom was sent to work in a communications centre in a command bunker in London, where he connected telephone calls from war leaders to the prime minister. He met Winston Churchill on several occasions when asked for updates on incoming calls.Wisdom then joined the Royal Corps of Signals, and performed a similar military function at the unit headquarters in Cheltenham, Gloucestershire.

Whilst performing a shadow boxing routine in an army gym, Wisdom discovered he had a talent for entertainment, and began to develop his skills as a musician and stage entertainer. In 1940 aged 25, at a NAAFI entertainment night, during a dance routine, Wisdom stepped down from his position in the orchestra pit, and started shadow boxing. Hearing his colleagues and officers giggling, he broke into a duck waddle, followed by a series of facial expressions. He later described the reaction as: "They were in hysterics. All the officers were falling about laughing."

Wisdom later said this was where he first patented his persona as "The Successful Failure". Over the next few years, until he was demobilized in 1945, his routine included his characteristic singing and the trip-up-and-stumble. After Wisdom appeared at a charity concert at Cheltenham Town Hall, actor Rex Harrison came backstage and urged him to become a professional entertainer.
