He was a regular on BBC Radio's
Twenty Questions and was voted Personality of the Year in the National Radio Awards of 1953-4. Harding regularly appeared on the BBC television panel game ''
What's My Line?'' as a panellist, having been the presenter of the very first episode in 1951. Harding was notorious for his irascibility and was at one time characterised in the tabloid press as "the rudest man in Britain". His fame sprang from an inability to
suffer fools gladly, and many 1950s TV viewers watched ''What's My Line?'' less for the quiz elements than for the chance of a live Harding outburst. An incident on an early broadcast started this trend when Harding became annoyed with a contestant, and told him that he was getting bored with him. In 1960 he was reduced to tears on an edition of the
Face to Face series, after being questioned by the host
John Freeman. As the focus of the interview moved on to the subject of death, Freeman asked Harding if he had ever been in the presence of a dead person. At this point, in replying in the affirmative, Harding's voice began to break and his eyes watered. Freeman later said he had not anticipated the effect this would have; Harding had witnessed his mother's death in 1954. Freeman appeared to be unaware that Harding was referring to his mother, for later in the interview he asserted that Harding's mother was still alive. Harding contradicted him and Freeman moved quickly on. This version of events has been contradicted by the producer,
Hugh Burnett. Freeman publicly expressed regret about this line of questioning. He was seen as a lonely
bachelor. Harding also admitted in the programme that his bad manners and temper were "indefensible". "[I'm] profoundly lonely", he stated, later adding, "I would very much like to be dead." ==Death==
