Before the electric shaver was successfully marketed, quite a few attempts were made to develop and promote variations of the device. The initial electric shaver patent was issued in 1898. A typical early model was called Lek-tro-shav and was sold in the 1910s. In order to work, a Lek-tro-shav had to be connected to a lightbulb socket. In the mid-1920s came the Vibro-Shave, whose handle included a tiny magnet and spring that also depended upon a lightbulb socket for its electric current.
Jacob Schick (1878–1937), a career U.S. Army officer, is credited as the inventor of what evolved into the modern-era electric shaver. Schick initially devised a shaver powered.
