Isobel, Lady Barnett, popularly known as Lady Isobel Barnett, was a Scottish radio and television personality, who had her highest profile during the 1950s and 1960s.
In 1953 she arrived on BBC television as one of the panel of What's My Line, which made her a household name. She appeared on the programme for ten years but was not an original panelist, her seat having been previously occupied by Marghanita Laski. She was regarded by audiences as elegant and witty, the epitome of the British aristocracy, although her title actually came from the fact that her solicitor husband had been knighted; the form Lady Isobel Barnett suggested she possessed a courtesy title, but she was not an aristocrat, nor had she married into the aristocracy. She also made regular appearances on the BBCradio seriesAny Questions, on the radiopanel gameMany a Slip and on the women's discussion series Petticoat Line. She was greatly in demand as an after-dinner speaker, a role into which she slipped confidently. In 1956, a reviewer predicted that an alien visiting from another planet could ask anyone between the ages of seven and 70 "What is What's my Line?" and "Who is Isobel Barnett?" and be confident of getting an answer. She featured in the first revival of What's My Line? which ran for two series from 1973-74.
In her last years, Barnett became reclusive and eccentric. In 1980 she was found guilty of shoplifting, and fined £75 for stealing a can of tuna and a carton of cream worth 87 pence from her village grocer. This brought her briefly back into the public eye; four days later on 20 October, she was found dead at her home in Cossington, Leicestershire. A coroner's inquest subsequently ruled that Barnett killed herself with an overdose of painkillers in her bath. During the inquest, police testified that she wore an extra spacious pocket, known as a poacher's pocket, inside her coat when she was caught stealing the groceries. Two days before her death, Barnett told an interviewer she was a compulsive thief and had been shoplifting for years. Finding that Barnett, a trained physician, killed herself deliberately with an overdose of arthritis painkiller, coroner Guy Tooze said, "She had recently suffered one of the most traumatic experiences any woman could suffer". Tooze went on to say, "I am satisfied she took a fatal overdose deliberately and knew what she was doing". A Daily Mail columnist said, “I am sorry for the generation of women among whom Lady Barnett finds herself. Often their lives, without a career and with children gone away from home, go racing downhill into sheer grinding boredom.” Barnett's story was recounted by several of her friends and colleagues in a 1991 BBC Radio 4 documentary in the Radio Lives series, in which it was said that she gave no indication to any of her friends that she was planning to take her own life, and that she kept up a façade of "business as usual".
