The slide rule was invented during the period of 1620-1650 by William Oughtred, based on the earlier invention of the Gunter scale by Edmund Gunter. The original slide rule is said to have been circular, and come about 1620 or 1625. The straight slide rule is said to have been invented around 1650.
