1930s: Miller Grows

Miller Electric Mfg. Co. was incorporated in 1935. The next year, Al Mulder, Miller's sole engineer, invented the world's first high frequency-stabilized AC industrial welder. This improved the quality of the welding arc, making AC welding practical for use in factories and construction.

Noteworthy Inventions of the 1930s

1930: Clarence Birdseye patents his frozen food process and 3M engineer Richard Drew patents Scotch tape.

1938: Patent attorney and physicist Chester Carlson invented the process that would eventually be named Xerography (“dry copy”).

1939: Air and land travel take legendary leaps. Igor Sikorsky invents the first successful helicopter.
