AnswerThe slide rule was invented by William Oughtred in 1625. AnswerWe do not know the precise year. A circular slide rule was invented by William Oughtred some time about 1620, and a design of a similar slide rule by Delamain was printed in about 1630. The straight slide rule seems to have been invented later, some time around 1650.

The slide rule was invented by William Oughtred some time about 1620 or 1625.
The slide rule was invented in England, by William Oughtred, in about 1620. This probably happened in Albury, near Guildford, in Surrey, where he lived. Records are not specific.
William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier.

William Ougthered invent Slide Rule in 1622!
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.
in the 1600's
Before the invention of the pocket or handheld calculator, the slide rule was a popular tool for calculations. William Oughtred made the first slide rule by inscribing logarithms on wood or ivory. The use of slide rules continued until about 1974, after which electronic calculators became more popular.
The slide rule, also known as a slipstick, is a mechanical analog computer. The slide rule is used primarily for multiplication and division, and also for "scientific" functions such as roots, logarithms and trigonometry, but does not generally perform addition or subtraction. William Oughtred and others developed the slide rule in the 1600sThere are pictures and information about slide rules at the Wikipedia article listed in the related links below.
