RT Unpublished Material DB /z-wcorg/ DS http://worldcat.org ID 145429778 LA English T1 ENIAC Trial Exhibits Collection, YR 1864 AB The collection includes the plaintiff's and defendants' trial exhibits presented in the patent case of Honeywell Incorporated vs. Sperry Rand Corporation and Illinois Scientific Developments, Incorporated. The plaintiff's trial exhibit series contains documents that supported the major claims of Honeywell Incorporated in their suit. It contains correspondence, research notes, scientific and publicity articles, schematic drawings, photographs and charts. There is large amount of documentation regarding the research and development of the ENIAC and subsequent computers developed by J. Presper Eckert, Jr., and John W. Mauchly up to around 1951. Most of the material covering the period after 1950 relates to the Sperry Rand's efforts to finalize the patent for the ENIAC and to assert its rights to the major technological claims therein (to support Honeywell's claims of antitrust actions). In addition, the plaintiff's exhibits include material that demonstrated the state of computer research undertaken by others in the 1930s and 1940s. The efforts of Vannevar Bush and Samuel H. Caldwell at MIT, Vladimir Zworykin and Jan Alesander Rajchman at RCA, and Joseph R. Desch and Robert E. Mumma at National Cash Register Company are documented here. Their most significant records relate to the research of John Vincent Atanasoff and Clifford E. Berry at Iowa State College and the degree of contact and exchange between Mauchly and Atanasoff. Honeywell also submitted copies of the testimony and depositions of a number of the key figures in the development of the ENIAC and early computers. The Defendants' trial exhibits series contain a complete copy of the United States Patent Office file for the ENIAC patent as well as a heavy concentration of secondary source material, in the form of copies of patents and articles from scientific and technical journals. All contents of this series generally falls within the date span of 1930 to 1965. The series does include correspondence, drawings, research notes, and reports; however, a large portion of the series contains published material such as journal and magazine articles, patents, technical reports and computer manuals. There is much more material in this series that relates to the internal organization, development and research of the Eckert Mauchly Computer Company. There is a large collection of original design drawings for the ENIAC.
