Who invented the Electric Motor in 1873?

In today's world, electric motors are everywhere.  You can see them in hybrid cars and you can see them in can openers.

Electric motors were not invented in 1873.  The first electric motor -- one that used electric current to produce mechanical motion, was invented by an American physicist named Joseph Henry in 1831.

However, as with a lot of inventions, the first inventor was not the one who made the device practical.

In 1873, Zenobe Gramme, a Belgian inventor, invented the first commercially practical (one which could be made reliably and cheaply enough to sell commercially) electric motor.
