The Mechthild Esser Nemmers Prize in Medical Science, established in 2016, is awarded every other year by Northwestern University Feinberg School of Medicine. The recipient is "a physician-scientist whose body of research exhibits outstanding achievement in their discipline as demonstrated by works of lasting significance". The winner is determined by a jury of biomedical scientists and receives $200,000. The award is one of five Nemmers Prizes awarded by the University, created as a gift to Northwestern by the late brothers Erwin Esser Nemmers and Frederic Esser Nemmers.
