Since 2005 the Oughtred Society Award Committee has annually honoured any outstanding contribution to the world community involved with slide rules and historical calculating instruments with a prestigious Award. Alongside any such Award, the Committee can also annually bestow a Fellowship on a member for substantial contributions to the Oughtred Society itself.
