Keith James Laidler

Physical Chemistry

A pioneer in the field of chemical kinetics and activated-complex theory

After working as a scientist in England for Canada during World War II, Laidler eventually became a professor of chemistry at the University of Ottawa in Canada (1955). His specialty, chemical kinetics, concerns the energy disposition of molecular reactions. He is also an expert on activated complex theory which involves the mechanism whereby starting materials, and sometimes catalysts, combine to form intermediate complex states that go on to become the reaction products. He applied his expertise to the chemistry of enzymes and other biochemical processes and wrote numerous books, including Chemistry of Enzymes 1954; Principles of Chemistry 1966; The World of Physical Chemistry 1993, and many others. He has received many awards, including the Tory and Centenary Medals from the Royal Society of Canada.
