Dimbleby also showed stamina and imperturbability in marathon election night broadcasts which ran from 10pm, when the polls closed, until around 6 or 7am the following morning. During his time with "Panorama", Dimbleby narrated the famous spaghetti-tree hoax on 1 April 1957, as an April Fool's Day joke. After commentating for half an hour on Elizabeth II's state visit in 1965 to Germany, Dimbleby uttered the mild expletive, "Jesus wept," unaware that the microphone was live, after discovering that the TV pictures had failed for all 30 minutes, meaning he would have to repeat the commentary again. Dimbleby married Dilys Thomas in Copthorne, West Sussex in 1937. The couple had four children, two of whom, David and Jonathan, have followed in his footsteps to become major broadcasting figures in their own right, both anchoring election night broadcasts (David on the BBC, Jonathan on ITN). In addition, Dimbleby's third son, Nicholas, sculpted the plaque in his father's name that was placed in Poets' Corner in 1990. In June 1946, Dimbleby was appointed Officer of the Order of the British Empire (OBE) for services as a war correspondent. In the 1959 Queen's Birthday Honours, he was promoted to Commander of the Order of the British Empire (CBE). On 22 December 1965, Dimbleby died in St Thomas' Hospital, London, at the age of 52. He had been suffering from testicular cancer which had been diagnosed five years earlier. Two weeks before his death, he presented a documentary on the links between heavy tobacco smoking and lung cancer. Dimbleby decided to admit he was ill with cancer, which, at the time, was a taboo disease to mention. It was helpful in building public consciousness of the disease and investing more resources in finding a cure. The Richard Dimbleby Cancer Fund was founded in his memory. Dimbleby was cremated, the ceremony receiving national publicity. In 1986 "Celebration of a Broadcaster", commemorating Dimbleby, was held in Westminster Abbey. In April 2013 he was honoured by the Royal Mail in the UK, as one of six people selected as subjects for the "Great Britons" commemorative postage stamp issue. The Richard Dimbleby Lecture was founded in his memory in 1972 and is delivered every year by an influential public figure. Speakers have included:
