Ever heard of John Barry? Not the Bond composer - the other one.
I hadn't until I read his obituary. Chances are you have had cause to thank Mr Barry for his invention at least once in the past month. Mr Barry, you see, was the man behind WD-40, and as such did more to contribute to day to day life than many far more exalted names.
Have a read of his obit. It's a fascinating case study.
