Inventor and pioneer in magnetic data storage, Bryce was one of America's most prolific inventors, credited with more than 500 U. S. and foreign patents. His death in 1949 took from the scientific and engineering world a brilliant talent that had poured forth an incessant stream of creative thought for almost half a century.
Although Bryce was one of ten men honored as the "greatest living inventors" at the centennial celebration of the U. S. Patent Office in 1936, he shunned the limelight and was little known outside his special field, the invention and design of control mechanisms and computing devices. He made many major contributions to worldwide use of high-speed calculating machines.
