Around 1921, Andis developed a hair clipper powered by a small electric motor. He sold his share of the existing business to his partners and launched the Andis Magnetic Clipper in 1922. This small, hand-held electric clipper was lighter and delivered high performance.By the 1940s, Andis Clipper had grown to become one of the world’s leading producers of professional barber tools. Separate product lines were created for livestock grooming and pet grooming. Innovations continued, including a rechargeable, battery-powered cordless clipper in 1968.
