Gilbert Newton Lewis was born in Weymouth, Massachusetts, October 23, 1875. He was a leading chemist who studied chemical bonds.

He received a doctorate from Harvard University in 1899. In Germany, he studied at Leipzig and Göttingen. He directed the Weights and Measures office at the Governmental Laboratory in the Philippines from 1904 to 1905. He did some work on thermodynamics. He was a professor of physical chemistry at the Massachusetts Institute of Technology from 1907 to 1912. Still in 1912, he moved to the University of California, Berkley.

In 1916, he began to develop the idea that chemical bonds are based on electron sharing and transfer. For this reason, its name is linked to a general definition of acids and bases. He published his ideas in Valence and the Structure of Atoms and Molecules in 1923.

In 1933, he isolated deuterium, which is one of the isotopes of hydrogen, which forms heavy water. It was Lewis who introduced the design of the valence layers of atoms in chemical bonds to facilitate visualization of electron transfers and sharing.

Lewis died in Berkley, California on March 23, 1946.
