Sir Dominic Corrigan (b. 1802, in Thomas Street, Dublin, Republic of Ireland; d. Merrion Square, Dublin, 1880) was a physician, known for his original observations in heart disease. The abnormal "collapsing" pulse of aortic valve insufficiency is named Corrigan's pulse after him. The son of a dealer in agricultural tools, Corrigan was educated in St. Patrick's College, Maynooth, which then had a department for secular students apart from the ecclesiastical seminary. He was attracted to the study of medicine by the physician in attendance, and spent several years as apprentice to the local doctor, Edward Talbot O'Kelly. Corrigan studied medicine in Dublin between 1820 and 1825, before going to Edinburgh where he received his degree as M.D. in August 1825.
