John M. Fluke, Sr. was granted a patent for the VAM (Volts, Amps, Watts) meter instrument in 1947 and founded Fluke Corporation in the basement of his home in Springdale, Connecticut, the following year. Fluke, who was born and raised in Seattle, moved his company to the Ballard neighborhood in 1952. In 1981, Fluke opened a 500,000 square feet, $26 million corporate headquarters in Everett for manufacture and research and development. As of 2019, Fluke Corporation is a world leader in the design, manufacture and sale of electronic test and measurement equipment and has expanded into the biomedical and network testing and monitoring fields.
