Dr. George Cogswell received his preliminary education at Atkinson Academy, where his love for scientific investigation soon became manifest. He commenced the study of medicine with his father, whose wise instruction and safe counsel did much to shape the future career of the aspiring student. In his desire for a wider culture in the line of his chosen profession, he became a private student to Reuben D. Mussey. M. D., L.L. D., and for two years enjoyed the instruction of this distinguished lecturer on anatomy and surgery. Early in 1830, he became a pupil of John D. Fisher, M. D., of Boston, who, at that time, was the most noted auscultator in New England. Dr. Fisher showed his confidence in his ambitious student by giving him the main practical charge of the House of Industry, at that time located in South Boston. The grateful pupil held the most intimate relations with his distinguished teachers during their lives. [Illustration: Geo. Cogswell.] In 1830 he was graduated Doctor of Medicine from Dartmouth College, with the honors of his class, and the same college conferred upon him the honorary degree of Master of Arts in 1865. Dr. Cogswell at once commenced the practice of his profession in Bradford, Mass., in August, 1830, and soon entered into a large and successful business. He brought to his work the discipline of hard and intelligent study, and his great desire was to advance the standard of medical practice in Essex county. He was the first physician in "Essex North" who made intelligent use of auscultation and percussion in the diagnosis of disease.
