## Bio

Born in 1845 in what's now Ukraine to a Moldavian noble father and Ukrainian-Jewish mother, Mechnikov's lineage was claimed by five nations though he eventually settled in France. His 1882 discovery of phagocytes — cells that devour invaders — revealed the body's innate immune defense and laid the groundwork for cell-mediated immunity while Ehrlich completed the picture with humoral immunity. Beyond immunology, he coined the term "gerontology" in 1903 and championed lactic acid bacteria for longevity, an idea that became the foundation of probiotics. He died in 1916, but life-extension advocates still mark May 15 as Metchnikoff Day.
