Chlorothiazide History

The Research team of Merck Sharp and Dohme Research Laboratories: Karl H. Beyer, Jr., M.D., Ph.D.; James M. Sprague, Ph.D.; John E. Baer, Ph.D.; and Frederick C. Novello, Ph.D. created a new series of medications, the thiazide diuretics, which includes chlorothiazide. They won an Albert Lasker Special Award in 1975 for its creation.
