Louis Yolando Mazzini (3 June 1894 – 23 June 1973) was a Peruvian-American scientist, who worked as a professor of serology and pathology at the Indiana University School of Medicine (IUSM) from 1924 to 1965. Originally from Lima, he developed a test for syphilis called the "Mazzini Test" in 1939, which had better specificity than other syphilis tests at the time. He also developed the Mazzini Optical Ground Glass Slide in 1977.
