Authors: Edmund Gunter (1581-1626) & William Oughtred (1574-1660)
Invention of a mechanical device, containing a logarithmic scale of equal parts and trigonomic functions which, with the aid of a pair of calipers, could be used as a slide rule. This device, called "Gunter's scale,'' or the "gunter'' by seamen, was soon replaced by a true slide rule, containing two parallel logarithmic scales

Author: Wilhelm Schickard (1592-1635)
The first known adding machine, a mechanical calculator called the "Calculating Clock.'' It could add and subtract up to six-digit numbers, based on the movement of six dented wheels geared through a "mutilated" wheel which with every full turn allowed the wheel located at the right to rotate 1/10th of a full turn

Author: Etienne-Jules Marey (1830-1904)
Graphic representation of a train schedule showing rate of travel along the route from Paris to Lyon. The method is attributed to the French engineer Ibry, but new evidence suggests that Lt. Sergeev had developed this method approximately 30 years earlier in Russia.
