Louis Plack Hammett (April 7, 1894 – February 9, 1987) was an American physical chemist. He is known for the Hammett equation, which relates reaction rates to equilibrium constants for certain classes of organic reactions involving substituted aromatic compounds. He is also known for his research into superacids and his development of a scheme for comparing their acidities based on what is now known as the Hammett acidity function. The Curtin–Hammett principle bears his name.
Hammett grew up in Portland, Maine, and studied in Harvard and Switzerland. He earned his Ph.D. at Columbia University. He authored an influential textbook on physical organic chemistry, and is credited with coining the term.
