It is the world's only institution dedicated to the industry-wide preservation of information processing devices and documentation. It interprets computer history through exhibits, publications, videotapes, lectures, educational programs, excursions, and special events. Hours and Services The Digital Computer Museum is open to the public Sunday through Friday, 1:00 pm to 6:00 pm. There is no charge for admission. The Digital Computer Museum Lecture Series Lectures focus on benchmarks in computing history and are held six times a year. All lectures are videotaped and archived for scholarly use. Gallery talks by computer historians, staff members and docents are offered every Wednesday at 4:00 and Sunday at 3:00. Guided group tours are available by appointment only. Books, posters, postcards, and other items related to the history of computing are available for sale at the Museum Store. The Museum's lecture hall and reception facilities are available for rent on a prearranged basis. For information call 617-467-4443. BOARD OF DIRECTORS Charles Bachman C.

International History of Computing © Edward Vanhoutte - 1 International History of Computing A selective overview (1614-1961) Edward Vanhoutte [email protected] Year Event Country 1614 John Napier (1550-1617) published Mirifici logarithmorum canonis GB descriptio in which he discussed his logarithms. 1622 William Oughtred (1574-1660) invented the slide rule which offered a GB quicker way to calculate logarithms 1623 Wilhelm Schickard (1592-1632) devised a calculating machine that DE enabled Johannes Kepler (1571-1630) to calculate the orbit of the planet Mars by which he proved that the sun and not the earth was the centre of the system. 1642 Blaise Pascal (1623-1662) constructed the Pascaline, an adding and FR subtracting machine that could automatically carry over amounts from a lower monetary unit to a higher monetary unit by applying distributed counting. The machine consisted of seven and later eight wheels, the first of which would count from 1 to 9, the second would count from 10 to 99, the third would count from 100 to 999, etc. 1671 Gottfried Wilhelm von Leibniz (1646-1716) built a machine that could DE multiply (and divide) by repeated additions. This calculator was based on his invention of the stepped wheel, a cylinder with nine individual stepped teeth of increasing length. 1680- Broesel invented a weaver’s programming device consisting of little AT 1690 wooden bars and a closed loop of a linen strip. 1703 Gottfried Wilhelm von Leibniz (1646-1716) described the modern binary DE number system using 0 and 1 in his essay Explication de l’arithmétique binaire, qui se sert des seuls caractères 0 et 1, avec des remarques sur son utilité, et sur ce qu’elle donne le sens des anciennes figures Chinoises de Fohy. -
15-292 History of Computing
1/27/13 15-292 History of Computing Electromechanical & Analog Computing Based on slides originally published by Thomas J. Cortina in 2004 for a course at Stony Brook University. Revised in 2013 by Thomas J. Cortina for a computing history course at Carnegie Mellon University. The typewriter First practical typewriter invented by Christopher Latham Sholes in 1867 Soon sold by Remington One historian of manufacturing has noted, the “typewriter was the most complex mechanism mass produced by American industry, … , in the 19th century” Pioneered 3 key features of the office machine industry (and thus later the computer industry) 1. The perfection of the product & low-cost manufacture 2. A sales organization to sell the product 3. A training organization to enable workers to use the technology 1 1/27/13 Other office technologies Adding Machine Arithmometer by Thomas de Colmar of Alsace (1820) impractical, slow to manufacture Comptometer by Dorr E.
