- Ada is the result of a
- collective effort to design a common language
- for programming large scale and real-time systems.
-
- The common high order language program began in 1974. The
- requirements of the United States Department of Defense were formalized in a series of documents which
- were extensively reviewed by
- the Services, industrial organizations, universities, and foreign
- military departments.
- The Ada language was designed in accordance with the final (1978)
- form of these requirements, embodied in
- the Steelman specification.
-
- The Ada design team was led by Jean D.
- Ichbiah and has included
- Bernd Krieg-Brueckner, Brian A. Wichmann,
- Henry F. Ledgard, Jean-Claude Heliard, Jean-Loup Gailly,
- Jean-Raymond Abrial, John G.P. Barnes,
- Mike Woodger, Olivier Roubine, Paul N. Hilfinger,
- and Robert Firth.
-
- At various stages of the project,
- several people closely associated with the
- design team made major contributions.
- They include J.B. Goodenough, R.F. Brender, M.W. Davis, G. Ferran, K. Lester,
- L. MacLaren, E. Morel, I.R. Nassi, I.C. Pyle, S.A. Schuman,
- and S.C. Vestal.
-
- Two parallel efforts that were started in the
- second phase of this design had a deep influence on the language.
- One was the development of a
- formal definition using denotational
- semantics, with the participation of
- V. Donzeau-Gouge, G. Kahn, and B. Lang.
- The other was the design of a test translator
- with the participation of K. Ripken, P. Boullier, P. Cadiou,
- J. Holden, J.F. Hueras, R.G. Lange, and D.T. Cornhill.
- The entire effort benefitted from the
- dedicated assistance of Lyn Churchill and Marion Myers,
- and the effective technical support of B. Gravem, W.L. Heimerdinger, and P. Cleve. H.G. Schmitz
- served as program manager.
-
- Over the five years spent on this project,
- several intense
- week-long design reviews were conducted,
- with the participation of P. Belmont, B. Brosgol, P. Cohen,
- R. Dewar, A. Evans, G. Fisher,
- H. Harte, A.L. Hisgen,
- P. Knueven, M. Kronental, N. Lomuto, E. Ploedereder, G. Seegmueller,
- V. Stenning, D. Taffs,
- and also F. Belz, R. Converse,
- K. Correll, A.N. Habermann, J. Sammet, S. Squires,
- J. Teller, P. Wegner, and P.R. Wetherall.
-
- Several persons had a constructive influence with
- their comments, criticisms and suggestions.
- They include P. Brinch Hansen, G. Goos,
- C.A.R. Hoare, Mark Rain, W.A. Wulf, and also
- E. Boebert, P. Bonnard,
- H. Clausen, M. Cox, T. Froggatt,
- H. Ganzinger, C. Hewitt, S. Kamin, O. Lecarme, J.L. Mansion,
- F. Minel, T. Phinney, J. Roehrich, V. Schneider, A. Singer, D. Slosberg,
- I.C. Wand, the reviewers of Ada-Europe, those of AdaTech and Afcet,
- and those of the Tokyo study group assembled
- by N. Yoneda, E. Wada, and K. Kakehi.
-
- These reviews and comments, the numerous evaluation reports
- received at the end of the first and second
- phase, the nine hundred language
- issue reports and test and evaluation reports received from
- fifteen different countries during the third
- phase of the project, the thousands of comments received during the Ansi Canvass, and
- the on-going work of the IFIP Working Group 2.4
- on system implementation languages and that of the Purdue Europe LTPL-E committee,
- all had a substantial influence on the final definition of Ada.
-
- The Military Departments and Agencies have provided a broad base of
- support including funding, extensive reviews, and countless individual
- contributions by the members of the High Order Language Working Group
- and other interested personnel. In particular, William A. Whitaker
- provided leadership for the program during the formative stages.
- David A. Fisher was responsible for the successful development
- and refinement of the language requirement documents that led to the Steelman
- specification.
-
- This language definition was developed
- by Cii Honeywell Bull and later Alsys, and by Honeywell Systems and Research Center,
- under contract to the
- United States Department of Defense.
- William E. Carlson and later Larry E. Druffel served
- as the technical representatives of the United States Government and effectively
- coordinated the efforts of all participants in the Ada program.
