Way back in 1790 (the US was brand-spankin'-new)--May 8th to be precise--The French National Assembly decided that the length of the new meter would be equal to the length of a pendulum with a half-period of one second. 

Fast forward to 1983 the meter is now defined as equal to the length of the path traveled by light  in vacuum during a time interval of 1299,792,458 of a second.

Progress. 

Just sayin'.

Okay, the picture is the standard for the kilogram, not the meter. But, it's the only thing close i could find.
