Gilbert N. Lewis
American physical chemist (1875–1946)
Gilbert Newton LewisForMemRS[1] (October 23[2][3][4] or October 25, 1875 – March 23, 1946)[1][5][6] was an American physical chemist and a dean of the college of chemistry at University of California, Berkeley.[3][7] Lewis was best known for his discovery of the covalent bond and his concept of electron pairs; his Lewis dot structures and other contributions to valence bond theory have shaped modern theories of chemical bonding. Lewis successfully contributed to chemical thermodynamics, photochemistry, and isotope separation, and is also known for his concept of acids and bases.[8] Lewis also researched on relativity and quantum physics, and in 1926 he coined the term "photon" for the smallest unit of radiant energy.[9][10]

“Gilbert Newton Lewis was born near Boston, October 23, 1875. At the age of nine he was taken by his parents to live in Lincoln, Nebraska, where his schooling, though meager, was sufficient to admit him to the preparatory school of the University of Nebraska in 1889. Here he remained until the end of the sophomore year. In 1893 he transferred to Harvard College, and, after graduating in 1896, he spent a year in teaching at Philips Academy at Andover. He then returned to Harvard for graduate work and received the A.M. degree in 1898 and the Ph.D. in 1899. After remaining for one year at Harvard as instructor, he went abroad on a traveling fellowship and had a semester with Ostwald at Leipzig and one with Nernst at Göttingen. The following three years he spent at Harvard as instructor, and then accepted a position as Superintendent of Weights and Measures in the Philippine Islands, and chemist in the Bureau of Science at Manila.

Isaac Newton Lewis
United States Army officer
Isaac Newton Lewis (October 12, 1858 – November 9, 1931) was a United States Army officer and the inventor of the Lewis gun.[1]
Biography
Lewis was born in New Salem, Pennsylvania on October 12, 1858. He graduated from the United States Military Academy in 1884 and was commissioned as a second lieutenant in the Second Artillery.[2] 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,[1] 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 he was retired the next month for disability incurred in line of duty.[2]
In 1911, he refined an original machine gun design of Samuel Maclean and began active marketing of a type which came to be known simply as the "Lewis Gun", which was used in World War I by the Allied armies, the United States Navy, and the a
