* Early Precursors: While not technically "hair clippers," early civilizations used tools like sharp stones, seashells, and animal bones for trimming hair.
* First Electric Clippers: The first electric clippers were patented in 1919 by Leo J. Wahl in Sterling, Illinois. These were bulky, heavy devices primarily used for barbering in salons.
* Development & Refinement: Over the following decades, hair clippers were constantly refined. Innovations like lighter materials, more powerful motors, and adjustable blades significantly improved functionality and convenience.
Therefore, while 1919 marks the invention of the first electric hair clippers, the evolution of the technology continued well beyond that year.
