It often turns what could be a very fruitfull career- with contributions to a breakthrough- into a one-trick-pony. My grandfather, a professor for chemistry, did as a student research on ion exchange resin - which later became valuable applied to water softeners. He did a lot of interesting research later when it came to analytical sciences (radio-chemistry) but that early success sort of over-shadowed everything. Its a haunting experience, unless you dono longer externalize your value as a researcher.
