Question: Is it true that Benjamin Franklin invented an odometer?

Answer: Yes. While Franklin (1706-90) was postmaster in Philadelphia, he created an odometer to measure postal route distances and attached the contraption to his carriage. However, other inventors preceded him.

Roman engineer Vitruvius (1st century B.C.) once described an odometer. He is generally credited as the first inventor, although some historians believe that the actual creator was Greek scientist Archimedes (c.287-212 B.C.). 1st century Greek scientist Heron (aka Hero) of Alexandria also described an odometer in his work Dioptra. Chinese scholar Zhang (aka Chang) Heng (78-139 A.D.), invented an odometer, as well. French scientist Blaise Pascal (1623-62) came up with an odometer prototype called the Pascaline, and English engineer Thomas Savery (c.1650-1715) invented an odometer for ships.
