Isaac Newton Lewis

Isaac Newton Lewis (October 12, 1858, New Salem, Pennsylvania – November 9, 1931, Hoboken, New Jersey) was a United States Army officer and the inventor of the Lewis Gun.

He graduated from the United States Military Academy in 1884 and was commissioned second lieutenant in the Second Artillery. Early in his career he made himself an authority on ordnance. In 1900, then-Captain Lewis was sent by Adjutant General Henry Clarke Corbin to Europe to study that subject, his report resulting in the re-armament of the field artillery. By successive promotions, he rose to the rank of colonel in the Coast Artillery Corps in August 1913, and was retired the next month for disability incurred in line of duty.
