Biography Timeline


In the early 1930s, Johnson, then a high school science teacher in Michigan, invented an electronic test scoring machine that sensed pencil marks on a standardized form based on the multiple choice test created by Columbia University professor Benjamin D. Wood. IBM bought the rights to Reynold's invention and hired him as an engineer to work in their Endicott, New York laboratory. The test scoring machine was sold as the IBM 805 Test Scoring Machine beginning in 1937.


In 1952, IBM sent Johnson to San Jose, California, to set up and manage its West Coast Laboratory. In 1956, a research team led by Johnson developed disk data storage technology, which IBM released as the IBM 305 RAMAC. Although the first disk drive was crude by modern standards, it launched a multibillion-dollar industry.


Johnson retired from IBM in 1971. He obtained more than 90 patents. After his retirement, he developed the microphonograph technology used in the Fisher-Price "Talk to Me Books." The Talk to Me Books won a Toy of the Year award. This technology was also used by the National Audubon Society to aid bird watchers with songbird identification. He received the National Medal of Technology and Innovation from President Ronald Reagan in 1986.


The IEEE Reynold B. Johnson Information Storage Systems Award was established in 1991, and is each year presented to a small team or an individual that has made outstanding contributions to information storage systems.


Johnson was awarded the Franklin Institute's Certificate of Merit in 1996.


Johnson died in 1998, at the age of 92, of melanoma at Palo Alto, California.
