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.
William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier.
William Oughtred was the inventor of the Slide Rule which allowed mathematical operations such as multiplication and division to be calculated by reading values from graduated scales. Slide rules were still commonly used in the 1970's and early 1980's but with the invention of modern electronic calculators, the use of the slide rule has declined.
William Oughtred (1574 - 1660) was an English mathematician and scholar. He used previous work by Napier, Gunter, and Delamain design a circular slide rule. This made approximate calculations much easier and faster than other methods of the time. The slide rule was reinvented in a sliding bar format in the 1650s. In addition to making calculations easier, the slide rule made teaching of logarithms more understandable.
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.

He did not invent any computer, a computer is capable of automating a calculation without human assistance.What he did invent was the sliderule, an analog mechanical calculation aid. He was most likely after a faster way to do multiplication and division, as that is the main thing a sliderule does.

The slide rule was invented by William Oughtred some time about 1620 or 1625.
William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier.
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.

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.
