Louis Pasteur

Louis Pasteur, born in Dole, France, was a devout Catholic, which, for those keeping score at home, is generally considered "not Jewish." His family lineage is similarly devoid of any Semitic surprises, keeping his "O" score firmly in the zero column. Apparently, the secret to his scientific brilliance wasn't ancient Hebrew texts but rather, you know, science. And Catholicism. Which, again, not Jewish.

Despite his conspicuous lack of Jewish credentials, Pasteur delivered a monumental amount of "nachas" to humanity. His work on germ theory debunked spontaneous generation, saved countless lives through vaccines for rabies and anthrax, and, most importantly, made milk a lot less dicey. Without him, imagine all the sour dairy and deadly diseases we'd still be battling. A truly gentile genius.

His legacy includes the process of pasteurization, a word so common it’s practically a household appliance instruction. He proved that microorganisms cause disease and fermentation, essentially laying the groundwork for modern microbiology and ensuring that both wine and vaccines could be produced safely. He was so good, he even gets a pass on not being Jewish.
