Ukrainian-born Selman Waksman was a biochemist who discovered streptomycin, the first antibiotic effective against tuberculosis. He was born in 1888 in the village of Priluka, Russian Empire (now Ukraine), and immigrated to the United States in 1910. Waksman's groundbreaking research at Rutgers University led to the development of several antibiotics, including streptomycin, which revolutionized the treatment of bacterial infections and saved countless lives.
