Jerome "Jerry" Hal Lemelson (1923-1997) was an extraordinarily prolific American inventor. Inventions in the fields he patented made possible innovations such as fax machines, automated warehouses, industrial robots, cordless telephones, videocassette recorders and camcorders.

Lemelson's
over 500 patents make him the second most productive inventor in American history. Only Thomas Alva Edison surpassed him in total patents awarded. Both are in the vaunted 1% of inventors, which takes 28 or more patents.
Born to a middle-class family on Staten Island, N.Y., Lemelson designed, built, and flew model airplanes and later, after vision problems kept him out of the cockpit in World War II, created weapons systems for the Army Air Corps. After the war, he earned masters degrees in aeronautical and industrial engineering.
He pursued a traditional engineering career for a few years, but in 1958, shortly before the first of his two sons was born, he quit his last regular job and became a full-time professional inventor. He spent 16-hour days tinkering in his attic and endlessly jotting in his many notebooks. But patent license fees were scarce, so his wife, interior designer Dorothy Ginsberg Lemelson, was the family bread-winner.
In 1964, big money started rolling in, when Triax Co. of Cleveland licensed Lemelson patents describing an automated warehousing system. In 1974, Sony Corp. licensed an audiocassette drive mechanism, and in 1981 IBM ponied up $1 million for 20 of his patents in data and word processing.
At first loathe to turn to the courts, Lemelson gradually learned his way around the legal system. Starting in 1957 with a suit claiming a cereal company had purloined his toy mask design, Lemelson filed more than 20 lawsuits to protect his patents. Although he lost more often than he won, a series of victories in the 1980s made him wealthy-- to the tune of over $1 billion.
Lemelson was a staunch advocate for the rights of independent inventors; he served on a federal advisory committee on patent issues from 1976 to 1979.
In 1993, Lemelson and his family created the Portland-based
Lemelson Foundation, a philanthropy with the mission to support invention and innovation to improve lives in the U.S. and developing countries. To date, the Foundation has donated or committed more than $140 million in support of its mission.
