Shortly after graduation, he was awarded the Cleland Gold Medal from the university for "An Experimental Determination of Magnetic Moments in Absolute Measurements." In 1879 he became Professor of Telegraph Engineering in the Physical Laboratories in the Imperial University in Tokyo. In 1888, Dr. Gray was hired as Professor of Dynamic Engineering at Rose Polytechnic Institute of Technology, now Rose-Hulman Institute of Technologyin Terre Haute, Indiana.
