Dear Mr. Cornwell,
Is the Rev. William Oughtred, who invented the slide rule and introduced the use of the letter “x” to indicate multiplication, an ancestor of yours?
There is now an Oughtred Society for those who collect slide rules. I wonder what Uhtred might make of this.
Sincerely,
Richard Reich
Uhtred would wonder how well The Reverend William could slaughter his enemies. I knew he was credited with the slide-rule (that gene never came near me), but not that he devised the X for multiplication. Nor had I heard of the Oughtred Society. I had heard that he died of 'joy' on hearing of the King's restoration in 1660, but I suspect that's not true, sadly. I shall look into the Oughtred Society, but as someone who never understood the function of a slide rule I suspect I'm not qualified to join - but thank you anyway!
