Sir Richard Charles Nicholas Branson (born 18 July 1950) is a British industrialist, best known for his Virgin brand of over 360 companies. Branson's first successful business venture was at age 16, when he published a magazine called Student. He then set up an audio record mail-order business in 1970. In 1972, he opened a chain of record stores, Virgin Records, later known as Virgin Megastores and rebranded after a management buyout as Zavvi in late 2007. Branson's Virgin brand grew rapidly during the 1980s—as he set up Virgin Atlantic Airways and expanded the Virgin Records music label. Richard Branson is the 261st richest person in the world according to Forbes' 2009 list of billionaires, with an estimated net worth of approximately £2.6 billion (US$3.9billion). Branson was born at Stonefield Nursing Home in Blackheath, South London, the son of barrister Edward James Branson and Eve Branson (née Huntley Flindt). His grandfather the Right Honourable Sir George Arthur Harwin Branson, was a judge of the High Court of Justice and a Privy Councillor. Branson was educated at Scaitcliffe School (now Bishopsgate School) until the age of thirteen. He then attended Stowe School until he was sixteen. Branson has mild dyslexia and had poor academic performance as a student, but discovered his ability to connect with others. Branson is the eldest of four siblings. He has two sisters, Lindi and Vanessa. His brother, Ted, followed in his father's footsteps and became a barrister. Branson had poor academic records which contrasted with excellent performance in sports, especially swimming. With Joan Templeman he has two children, Holly (b. 1981) and Sam (b. 1984). He revealed in an interview with Piers Morgan that he and wife Joan had a daughter named Clare Sarah who died when she was just four days old in 1979. The couple wed—at their daughter Holly's suggestion when she was eight years old—in 1989 at Necker Island, a 74-acre (30 ha) island in the British Virgin Islands that Branson owns. He also owns land on the Caribbean Islands of Antigua and Barbuda. Holly Branson is now a doctor. Branson is a supporter of Oxford United. In 1998, Branson released his autobiography entitled Losing My Virginity, an international bestseller.[citation needed] In it, he wrote of feeling defenseless in a balloon: "I do not believe in God, but as I sat there in the damaged capsule, hopelessly vulnerable to the slightest shift in weather or mechanical fault, I could not believe my eyes." Branson was deeply saddened by the disappearance of fellow adventurer Steve Fossett in September 2007, and the following month wrote an article for Time magazine entitled "My Friend, Steve Fossett".
