It is commonly accepted that Louis Pasteur is the father of microbiology and Joseph Lister is the father of antisepsis. Middleton Goldsmith, a surgeon in the Union Army during the American Civil War, meticulously studied hospital gangrene and developed a revolutionary treatment regimen. The cumulative Civil War hospital gangrene mortality was 45 per cent. Goldsmith's method, which he applied to over 330 cases, yielded a mortality under 3 per cent. His innovative work predated Pasteur and Lister, making his success truly remarkable and worthy of historical and surgical note.
