                      THE OUGHTRED SOCIETY


  The Oughtred Society was founded in 1991 by a group of
  like-minded slide rule collectors. The original intent of
  the Society was to provide a venue for the exchange of
  information about slide rules. The organization was named for
  William Oughtred, an English clergyman and mathematician who
  is generally credited with the invention of both the linear
  and the circular slide rules.
