Sir Clive Sinclair

British Mensa honorary president Sir Clive Sinclair has died at the age of 81. The brilliant inventor and scientist will be missed by fellow members who remember the part he played in shaping our society.

Clive Sinclair joined Mensa in 1959 and, he said, was “highly surprised” to realise his IQ level – although it is considered impolite in Mensa circles to talk about results, we do know he registered at 159.

He initially attended Mensa events sporadically but was to go on to play a significant part in the society’s development.

He became chairman in 1980, at a time when fellow high profile members like Madsen Pirie, Brian J Ford, Victor Serebriakoff and David Schulman were raising both the profile and perception of Mensa.

Under Sir Clive’s chairmanship, which ran for 17 years, British Mensa enjoyed significant success, seeing its membership rising to almost 40,000 – largely on the back of advertising campaigns in the national press which also helped Mensa to become a ‘household name’.

Sir Clive stepped down from the board in 1997 but continued his involvement with the society, enjoying the company of many of its more eccentric – and what he described as fun-filled – characters of the time.

Sir Clive, who after his knighthood insisted members called him simply Clive, was also quite clear about what he thought Mensa was all about. “If the press gives the impression that Mensa is eccentric that is because it is,” he once said.

In more recent times Sir Clive rarely attended Mensa events but he nevertheless maintained a fondness for the society and remained proud of his membership and, in particular, the fact that he was our honorary president, along with Francesca Quint, wife of the late Lance Ware.

He will hold a very permanent place in the history of the society.

Mensa Chief Executive Cath Hill said: “Sir Clive Sinclair was one of the people who helped to shape Mensa, making it a well known society among the general public and attracting large numbers of new members. He was a man known for his brilliance in the field of invention but Mensa members will also remember him as just a brilliant man.”                                                                                                              Brian Page
