Guinness Book of Records co-founder Norris McWhirter died in London on Monday, April 19, 2004, at the age of 78 after suffering a heart attack, his family said. McWhirter fell ill while playing tennis at his home in Wiltshire, southern England, on Monday evening, a family spokeswoman said Tuesday. As founding editor of the Guinness Book of Records, McWhirter produced a publication that came to be regarded as the final arbiter on questions of who holds what international record. By 1964, the publishers were selling 1 million copies a year and by 1981, annual sales topped 40 million.
