|Norm Larsen (1923-1970)|
As with a lot of boffins he never had a commercial brain. He sold the company not long after, complete with its only product, for a paltry $20,000 - no royalties, no residuals. He always reckoned on inventing something better; he never did. Larsen died in 1970.
The WD-40 company (they dropped the Rocket moniker 'because we don't sell rockets') now has an annual turnover in excess of $300 million.
These days WD-40 is one half of, along with duct tape, what is affectionately called the Redneck Tool Kit: if it isn't moving and it should: WD-40. And if it is moving and it shouldn't: duct tape.
