Norris McWhirter, co-founder of the Guinness Book of Records, has died aged 78, his family announced on Tuesday.
McWhirter suffered a heart attack while playing tennis at his Wiltshire home on Monday evening, his family said.
During the 1970s and 1980s he was a fixture of the BBC One children's show Record Breakers, hosted by Roy Castle.
McWhirter, whose identical twin brother Ross was murdered by the IRA in 1975, had also been a successful athlete and worked as a BBC sports journalist.
Like his brother, he also held strong political views.
McWhirter's family said in a statement: "Norris cared passionately about Great Britain, democracy and the rule of law and was always active in politics, but usually behind the scenes.
"The two things he attached most importance to were the freedom of the individual and the sovereignty of the United Kingdom.
"Apart from his family, his great loves were visiting the 1,049 offshore British islands and having a good game of tennis. He was energetic to the last."
McWhirter, an all-round sportsman, represented Scotland and Britain at running in the 1950s.
With brother Ross he set up the Guinness Book of Records in the mid-1950s.
Ross McWhirter, an outspoken critic of the IRA, was shot dead by the group after offering a large reward for information leading to the capture of IRA bombers.
Speaking about the murder in a TV programme in 2002, Norris McWhirter said: "I felt not so much bereaved but it was an amputation.
"You had sort of lost part of you - it is a very difficult thing to describe."
The twins held trenchant views and were vocal on a number of issues, including Northern Ireland.
They founded campaign group the Freedom Association, which campaigned strongly against British involvement in the European Union and other areas.
Both had enjoyed successful athletics careers before entering journalism and joining the BBC as sports commentators.
They co-presented Record Breakers, which first hit the nation's TV screens in 1972.
It was as the show's resident records expert that Norris McWhirter was best known to children of the 1970s and 1980s.
Each week he would answer from memory any question about records that the audience chose to ask, and the exchanges were never rehearsed.
Annual editions of the Guinness books, cataloguing human and natural extremes, have become best-sellers in many countries.
McWhirter continued to edit the volumes until 1986, remaining as advisory editor until 1996.
By 1999, the book had been translated into 37 languages and sold more than 87 million copies around the world.
McWhirter is survived by his wife Tessa, daughter Jane and son Alasdair.
