We've come a long way from computers programmed with wires and punch cards. Maybe not as far as some would like, though. Here are the innovations in programming.
, a German engineer working alone while hiding out in the Bavarian Alps, develops Plankalkul. He applies the language to, among other things, chess.
, the first computer language actually used on an electronic computing device, appears. It is, however, a "hand-compiled" language.
, working for Remington
Rand, begins design work on the first widely known compiler, named A-0. When the language is released by Rand in 1957, it is called MATH-MATIC.
Alick E. Glennie
, in his spare time at the University of Manchester, devises a programming system called AUTOCODE, a rudimentary compiler.
--mathematical FORmula TRANslating system--appears. Heading the team is John Backus, who goes on to contribute to the development of ALGOL and the well-known syntax-specification system known as BNF.
appears, able to handle subroutines and links to assembly language.
at M.I.T. begins work on LISP--LISt Processing.
The original specification for ALGOL
appears. The specific
ation does not describe how data will be input or output; that is left to the individual implementations.
is created by the Conference on Data Systems and Languages (CODASYL).
, the first block-structured language, appears. This is the root of the family tree that will ultimately produce the likes of Pascal. ALGOL goes on to become the most popular language in Europe in the mid- to late-1960s.
Sometime in the early 1960s
, Kenneth Iverson begins work on the language that will become APL--A Programming Language. It uses a specialized character set that, for proper use, requires APL-compatible I/O devices.
is documented in Iverson's book,
on the sure-fire winner of the "clever acronym" award, SNOBOL--StriNg-Oriented symBOlic Language. It will spawn other clever acronyms: FASBOL, a SNOBOL compiler (in 1971), and SPITBOL--SPeedy ImplemenTation of snoBOL--also in 1971.
Work begins on PL/1.
At Dartmouth University
, professors John G. Kemeny and Thomas E. Kurtz invent BASIC. The first implementation is a compiler. The first BASIC program runs at about 4:00 a.m. on May 1, 1964.
Work begins on LOGO
at Bolt, Beranek, & Newman. The team is headed by Wally Fuerzeig and includes Seymour Papert. LOGO is best known for its "turtle graphics."
, a much-enhanced SNOBOL, appears.
, a monster compared to ALGOL 60, appears. Some members of the specifications committee--including C.A.R. Hoare and Niklaus Wirth--protest its approval. ALGOL 68 proves difficult to implement.
, a FORTRAN variant, appears.
is officially defined by ANSI.
begins work on Pascal.
attend an APL conference at IBM's headquarters in Armonk, New York. The demands for APL's distribution are so great that the event is later referred to as "The March on Armonk."
Sometime in the early 1970s
, Charles Moore writes the first significant programs in his new language, Forth.
Work on Prolog
begins about this time.
Also sometime in the early 1970s
, work on Smalltalk begins at Xerox PARC, led by Alan Kay. Early versions will include Smalltalk-72, Smalltalk-74, and Smalltalk-76.
An implementation of Pascal
appears on a CDC 6000-series computer.
, a descendant of SNOBOL4, appears.
for Konrad Zuse's Plankalkul (see 1946) is finally published.
produces C. The definitive reference manual for it will not appear until 1974.
The first implementation of Prolog
-- by Alain Colmerauer and Phillip Roussel -- appears.
specification for COBOL appears.
by Bob Albrecht and Dennis Allison (implementation by Dick Whipple and John Arnold) runs on a microcomputer in 2 KB of RAM. A 4-KB machine is sizable, which left 2 KB available for the program.
Bill Gates and Paul Allen
write a version of BASIC that they sell to MITS (Micro Instrumentation and Telemetry Systems) on a per-copy royalty basis. MITS is producing the Altair, an 8080-based microcomputer.
, a LISP dialect by G.L. Steele and G.J. Sussman, appears.
Pascal User Manual
, by Jensen and Wirth, is published. Still considered by many to be the definitive reference on Pascal.
describes RATFOR--RATional FORTRAN. It is a preprocessor that allows C-like control structures in FORTRAN. RATFOR is used in Kernighan and Plauger's "Software Tools," which appears in 1976.
Design System Language
, considered to be a forerunner of PostScript, appears.
The ANSI standard for MUMPS
-- Massachusetts General Hospital Utility Multi-Programming System -- appears. Used originally to handle medical records, MUMPS recognizes only a string data-type. Later renamed M.
The design competition that will produce Ada
begins. Honeywell Bull's team, led by Jean Ichbiah, will win the competition.
and others set up FIG, the FORTH interest group. They develop FIG-FORTH, which they sell for around $20.
Sometime in the late 1970s
, Kenneth Bowles produces UCSD Pascal, which makes Pascal available on PDP-11 and Z80-based computers.
begins work on Modula, forerunner of Modula-2 and successor to Pascal.
-- a text-processing language named after the designers, Aho, Weinberger, and Kernighan -- appears.
The ANSI standard
for FORTRAN 77 appears.
develops a set of languages -- collectively referred to as "C With Classes" -- that serve as the breeding ground for C++.
on a common dialect of LISP, referred to as Common LISP.
the Fifth Generation Computer System project. The primary language is Prolog.
Smalltalk-80: The Language and Its Implementation
by Goldberg et al is published.
. Its name comes from Lady Augusta Ada Byron, Countess of Lovelace and daughter of the English poet Byron. She has been called the first computer programmer because of her work on Charles Babbage's analytical engine. In 1983, the Department of Defense directs that all new "mission-critical" applications be written in Ada.
In late 1983
and early 1984, Microsoft and Digital Research both release the first C compilers for microcomputers.
, the first implementation of C++ appears. The name is coined by Rick Mascitti.
, Borland's Turbo Pascal hits the scene like a nuclear blast, thanks to an advertisement in BYTE magazine.
A reference manual
for APL2 appears. APL2 is an extension of APL that permits nested arrays.

-- Common LISP Object System -- is published.
