Reynold (Rey) B. Johnson
Born 1906, Minnesota, Johnson devised a method for scoring multiple-choice tests by sensing conductive pencil marks on answer sheets, and initiated work leading to the first disk storage device.
Education: University of Minnesota.
Professional Experience high school teacher; IBM Corp., 1934-1971; founder, Education Engineering Associates Laboratory, Palo Alto, Calif., 1971-present.
Honors and Awards: IEEE Computer Society Pioneer Award, 1980; National Medal of Technology, 1986.
While a high school teacher in Michigan in 1931, Johnson devised a novel method for scoring multiple-choice tests by sensing conductive pencil marks on answer sheets; his method was subsequently purchased by IBM. He joined IBM as an engineer and was first head (1952) of the IBM San Jose Laboratory. He created the IBM 805 Test Scoring Machine in 1937. After opening the San Jose Laboratory, Johnson initiated work leading to the first disk storage device in 1955, first used with the IBM RAMAC computer. The storage device had a 24-inch-diameter magnetic-oxide-coated d

[modifier | modifier le code]Début de carrière
[modifier | modifier le code]Reynold Johnson est diplômé en administration scolaire en 1929, il commence sa carrière comme professeur de sciences et de mathématiques dans un collège local. Sa vie change en 1933, lorsqu'il perd son emploi et conçoit un appareil électromécanique capable de noter automatiquement un QCM en détectant les marques de crayon. Il s'adresse à plusieurs entreprises, dont IBM, afin de leur proposer son invention. IBM refuse de s'y intéresser dans un premier temps, mais en 1934, l'entreprise acquiert le brevet, voyant en Johnson un grand potentiel. Il est embauché comme ingénieur dans le laboratoire d'Endicott (New York).

Reynold B. Johnson
American inventor and computer pioneer
Reynold B. Johnson (July 16, 1906 – September 15, 1998) was an American inventor and computer pioneer. A long-time employee of IBM, Johnson is said to be the "father" of the hard disk drive. Other inventions include automatic test scoring equipment and the videocassette tape.
Biography
A native of Minnesota, born to Swedish immigrants, Johnson graduated from Minnehaha Academy (1925) and went on to graduate from the University of Minnesota (BS in Educational Administration, 1929).
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. IBM bought the rights to Reynold's invention[1] 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.
