I've been to Dijon, France (population 150,000) on multiple occasions
and regulars have received dispatches from those visits. And no, the buildings are not all mustard colored. This trip finds me in Dole (population 25,000), located about 25 miles south of Dijon. What's Dole's claim to fame? It's the birthplace of Louis Pasteur. This French chemist (1822-1895) doesn't receive enough credit for improving our quality of life. He's the man best known for inventing the technique of treating milk and wine to stop bacterial contamination, a process now called pasteurization. Did you know Louis (I wonder if his buddies called him Louie?) is also responsible for the first vaccines for rabies and anthrax? His medical discoveries were numerous but, he also made significant discoveries in chemistry. Pasteur's motivations for curing infectious diseases might have something to do with three of his five children dying of typhoid.
It isn't hard to find where Pasteur was born as there are numerous sign's around Dole pointing you in the right direction---like this brown arrow sign.
