Thomas Martin Lowry (1874-1936) was born in West Yorkshire, England. His father was a reverend. He became a chemistry professor at Guy's Hospital Medical School before becoming a physical chemistry professor at Cambridge University in 1920. His main research was the optical activities of solutions. This led him to propose the acid/base theory in 1923, the same year that Brønsted proposed it.

Johannes Brønsted (1879-1947) was born in Verde, Denmark. He became a professor of chemistry at the University of Copenhagen. In 1923, he proposed an acid/base theory. Besides acids and bases, Brønsted studied electrolytes, reaction kinetics, and thermodynamics. He was elected to Danish parliment in 1947, but died before he could take office.
