Rentschler graduated in 1903 with a bachelor's degree from Princeton University and in 1908 with a Ph.D. in physics from Johns Hopkins University. From 1908 to 1917 he was a professor of physics at the University of Missouri. In 1917 he began work for the Westinghouse Electric Company as a researcher at the Westinghouse Lamp Plant in Bloomfield, New Jersey and continued working there until his retirement in 1945. He became the research director at the Lamp Plant. In 1922 Rentschler, with John W. Marden, developed an important new process.

Rentschler patented more than 100 inventions, including the Westinghouse Sterilamp™, a lamp for killing bacteria by means of ultraviolet radiation. He was elected a fellow of the American Physical Society and a fellow of the Optical Society of America.

On 13 August 1904 in Shoemakersville, Pennsylvania, he married Margaret L. Bender.
