Arthur Williams Wright (September 8, 1836 – December 19, 1915) was an American physicist. Wright spent most of his scientific career at Yale University, where he received the first science Ph.D. outside of Europe. His research, which ranged from electricity to astronomy, produced the first X-ray image and experimented with Röntgen rays. He also proved instrumental in securing funding for the first dedicated physics lab building in the United States, the Sloane Physical Laboratory.
