Date:
1945-1959
Scope and Contents:
This collection consists of over 2,516 items, housed in 31 document boxes. The material is arranged into chronological order and covers the project dates of l945- l959. The items were originally classified secret, confidential, and unclassified.
The collection is arranged into four series:
Series 1: Summary Reports
Series 2: Bi-weekly Reports
Series 3: Correspondence, Memoranda, and Reports
Series 4: Indexes
The summary reports include originals of "Summary Report #1, April, 1946" and "Summary Report #2," in twenty-two volumes, and photocopies of summary reports #3 through #40. The bi-weekly reports, covering the period December, l947 to May, l953, are arranged chronologically. The bulk of the collection consists of correspondence, notes, memos, and reports. These date from August, 1945 to January, 1959 and are arranged chronologically. A 210 page index to the reports and correspondence (prepared by Whirlwind project personnel) is located in box 31. This guide has a table of contents and lists topic, author, date, and identification number for all items in the collection. Other indexes are located in boxes 30 and 31.

Biographical / Historical:
Project Whirlwind was sponsored by the Special Devices Center of the Office of Naval Research from 1945 to 1952. The original objective of the project was the development of a device that would simulate airplanes in flight. As the project progressed, other applications of the computer evolved.
The project was centered in the Servomechanisms Laboratory of the Massachusetts Institute of Technology (M.I.T.). In the course of the research, Whirlwind evolved from an aircraft simulator into a high speed digital computer and finally into a key element of the United States' early air defense system. In 1948, M.I.T., believing that it was inappropriate for an educational institution to be so heavily involved in air defense research, transferred Whirlwind responsibility to the new M.I.T. Lincoln Laboratory in 1952. There, under the direction of Jay Forrester, pioneering work was done on magnetic core memory. MITRE's Whirlwind group spun off from Lincoln Laboratory to the new MITRE Corporation in 1958. Whirlwind served SAGE (Semiautomatic Ground Environment) air defense activities until being retired in May of 1959.
Whirlwind I was of the high-speed electronic digital type, in which quantities were represented as discrete numbers, and complex problems were solved by the repeated use of fundamental arithmetic and logical operations. Computations were executed by fractional microsecond pulses in electronic circuits, of which the principal ones were the flip-flop, the gate coincidence circuit and the magnetic core memory. Whirlwind I used numbers of 16 binary digits; this length was selected to limit the machine to a practical size.
The Whirlwind I Computer was utilized by such projects as Navy Fire Control, Air Traffic Control, the Cape Cod System, Experimental SAGE Sector, and many others. Whirlwind I spawned two computers, the MTC (memory test computer) and TX O (transistor computer), both developed by ESS Installation Group 63.
The Whirlwind I Computer and its facilities were later leased to the Wolf Research and Development Corporation, West Concord, Massachusetts, under Navy Lease Contract Nonr 2956(00) in 1963. Kent C. Redmond and Thomas M. Smith wrote a history of the project, Project Whirlwind: Case History (Bedford, Massachusetts: The MITRE Corporation, 1975).
Provenance:
This collection was donated by the MITRE Corporation, February 1983. The Whirlwind I Computer Project originated at the Servomechanics Laboratory at the Massachusetts Institute of Technology (M.I.T.) in 1945. The records were transferred in 1959 to the MITRE Corporation.

Summary:
Records from Eric H. Clamons, fifth chairman of the American National Standards Institute (ANSI) X3L2 Standards Committee.
Scope and Contents:
This material includes correspondence, handwritten notes, transcripts of speeches, meeting minutes, reports (in draft and final form) of ANSI X3L2 and other committees and international organizations dealing with computer character sets and codes as well as minutes and agendas of their meetings. There are also some clippings of articles from journals and newspapers. There is no evident classification by subject, committee or chronology; the 10 data boxes each seem to have a random distribution of material, except that box 1 has a broader time span (1969-1979).
Organizations which created some of these documents include:
AFNOR: Association Francaise de Normalisation; ANSI: American National Standards Institute; (C)BEMA: (Computers and) Business Equipment Manufacturers Association; ECMA: European Computers Manufacturers Assn.
and ISO: International Organization for Standardization.
