1. TIMELINE OF PROGRAMMING LANGUAGES Presented by: Lanz Christian Buyao

2. How did it start? How It Started We first saw the "History of Programming Languages" diagram, created by Éric Lévénez, while visiting our French office. We were so taken with the level of detail and the visual impact of viewing 50 years of programming history that we wanted to come up with a way to share it more widely. We started big. We printed it out full-size, all 18 feet of it, on our plotter and ran it along a wall at our Mac OS X Conference last fall. So many people came by to make notations on the diagram that we knew there would be a lot more interest and discussion if we could only get it in a more manageable format. With Éric's permission, we collected comments from our authors, editors, and friends, and rebuilt the file so we could print it at its current dimensions, 39" x 17". Éric maintains a site with his original diagram, change logs, an explanation of how he creates his charts, and links to additional resources such as Bill Kinnersley's Language List of over 2,500 programming languages. Éric also has Windows and Unix historical diagrams that he makes available for non-commercial purposes, all at www.levenez.com.his original diagramwww.levenez.com

3. THE TIMELINE OF EVENTS IN CHRONOLOGICAL ORDER

4. Pre-1950’s Plankalkül is a programming language designed for engineering purposes by Konrad Zuse between 1943 and 1945. It was the first high-level non-von Neumann programming language to be designed for a computer. Plankalkül was not published at that time owing to a combination of factors such as conditions in wartime and postwar Germany and his efforts to commercialize the Z3 computer and its successors. In 1944 Zuse met with the German logician and philosopher Heinrich Scholz and they discussed Zuse's Plankalkül.Konrad Zuse 1943-1946 - ENIAC coding system created by John Von Neumann, John Mauchly, J. Presper Eckert, Herman Goldstine after Alan Turing. 1946 – ENIAC Short Code & Von Neumann and Goldstine graphing system 1947 - ARC Assembly by Kathleen Booth 1948 – CPC Coding Scheme and Curry Notation System by Howard Aiken and Haskell Curry 1949 - Short Code by John Mauchly and William F. Schmitt

5. 1950’s 1950 - Short Code was proposed by John Mauchly in 1949 and originally known as Brief Code. William Schmitt implemented a version of Brief Code in 1949 for the BINAC computer, though it was never debugged and tested. Short Code was one of the first higher-level languages ever developed for an electronic computer. Unlike machine code, Short Code statements represented mathematic expressions rather than a machine instruction. 1951 – Superplan by Heinz Rutishauser ALGAE by Edward A Voorhees and Karl Balke Intermediate Programming Language by Arthur Burks Regional Assembly Language by Maurice Wilkes.... And the list goes on. The Sort Merge Generator was an application developed by Betty Holberton in 1951 for the Univac I and is one of the first examples of using a computer to create a computer program. The A-0 system (Arithmetic Language version 0), written by Grace Hopper in 1951 and 1952 for the UNIVAC I, was the first compiler ever developed for an electronic computer. The A-0 functioned more as a loader or linker than the modern notion of a compiler.

6. 1950’s Glennie’s Autocode - The first autocode and its compiler were developed by Alick Glennie in 1952 for the Mark 1 computer at the University of Manchester and is considered by some to be the first compiled programming language..Alick Glennie Speedcoding or Speedcode was the first high order or high-level language created for an IBM computer. The language was developed by John Backus in 1953 for the IBM 701 to support computation with floating point numbers. The Laning and Zierler system (sometimes called "George" by its users) was one of the first operating algebraic compilers, that is, a system capable of accepting mathematical formulae in algebraic notation and producing equivalent machine code (the term compiler had not yet been invented and the system was referred to as "an interpretive program"). It was implemented in 1954 for the MIT WHIRLWIND by J. Halcombe Laning and Neal Zierler. The second autocode for the Mark 1 was planned in 1954 and developed by R. A. Brooker in 1955 and was called the "Mark 1 Autocode". The language was nearly machine-independent and had floating-point arithmetic, unlike the first one. 1954-1955 – FORTRAN Concept

7. 1950’s ARITH-MATIC is an extension of Grace Hopper's A-2 programming language, developed around 1955. ARITH-MATIC was originally known as A-3, but was renamed by the marketing department of Remington Rand UNIVAC. MATH-MATIC is the marketing name for the AT-3 compiler, an early programming language for the UNIVAC I and UNIVAC II. Intended as an improvement over FORTRAN. Created by a group led by Charles Katz in 1957. Information Processing Language (IPL) is a programming language created by Allen Newell, Cliff Shaw, and Herbert A. Simon at RAND Corporation and the Carnegie Institute of Technology at about 1956. Newell had the job of language specifier-application programmer, Shaw was the system programmer, and Simon took the job of application programmer-user. FLOW-MATIC, originally known as B-0 (Business Language version 0), was the first English- like data processing language. It was developed for the UNIVAC I at Remington Rand under Grace Hopper during the period from 1955 until 1959.

8. 1950’s PACT was a series of compilers for the IBM 701 and IBM 704 scientific computers. Their development was conducted jointly by IBM and a committee of customers starting in 1954. PACT I was developed for the 701, and PACT IA for the 704. The emphasis in that early generation of compilers was minimization of the memory footprint, because memory was a very expensive resource at the time. Lisp (historically, LISP) is a family of computer programming languages with a long history and a distinctive, fully parenthesize dPolish prefix notation. Originally specified in 1958, Lisp is the second-oldest high-level programming language in widespread use today; only Fortran is older (by one year). Like Fortran, Lisp has changed a great deal since its early days, and a number of dialects have existed over its history. Today, the most widely known general-purpose Lisp dialects are Common Lisp and Scheme.

9. 1950’s COMTRAN (COMmercial TRANslator) is an early programming language developed at IBM. It was intended as the business programming equivalent of the scientific programming language FORTRAN (FORmula TRANslator). It served as one of the forerunners to the COBOL language. Developed by Bob Bemer, in 1957, the language was the first to feature the programming language element known as a picture clause. In 1957, Charles Leonard Hamblin invented the programming language GEORGE. It was designed around a push-down pop-up stack for arithmetic operations, and employed reverse Polish notation. The language included loops, subroutines, conditionals, vectors, and matrices. IBM's FORTRAN II appeared in 1958. The main enhancement was to support procedural programming by allowing user-written subroutines and functions which returned values, with parameters passed by reference. COMIT was the first string processing language (compare SNOBOL, TRAC, and Perl), developed on the IBM 700/7000 series computers by Dr. Victor Yngve and collaborators at MIT from 1957-1965.

10. 1950’s 1958 - ALGOL 58, originally known as IAL, is one of the family of ALGOL computer programming languages. It was an early compromise design soon superseded by ALGOL 60. According to John Backus. ALGOL 58 introduced the fundamental notion of the compound statement, but it was restricted to control flow only, and it was not tied to identifier scope in the way that Algol 60's blocks were. FACT was an early computer programming language, created by the Datamatic Division of Minneapolis Honeywell for its model 800 series business computers in 1959. FACT was an acronym for "Fully Automated Compiling Technique". It was an influence on the design of the COBOL programming language. Some of the design of FACT was based on the linguistic project Basic English, developed about 1925 by C.K. Ogden. The software was actually designed by Computer Sciences Corporation (Fletcher Jones, Roy Nutt, and Robert L. Patrick) under contract to Richard Clippinger of Honeywell.

11. 1950’s COBOL is a compiled English-like computer programming language designed for business use. It is imperative, procedural and, since 2002, object-oriented. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL was designed in 1959 by the Conference on Data Systems Languages (CODASYL) and was partly based on previous programming language design work by Grace Hopper, commonly referred to as "the (grand)mother of COBOL". It was created as part of a US Department of Defense effort to create a portable programming language for data processing JOVIAL was developed as a new "high-order" programming language beginning in 1959 by a team at System Development Corporation (SDC) headed by Jules Schwartz to compose software for the electronics of military aircraft. The name JOVIAL is an acronym for "Jules Own Version of the International Algorithmic Language. JOVIAL is a high-level computer programming language similar to ALGOL, but specialized for the development of embedded systems (specialized computer systems designed to perform one or a few dedicated functions, usually embedded as part of a complete device including mechanical parts).

12. 1950’s MAD (Michigan Algorithm Decoder) is a programming language and compiler for the IBM 704 and later the IBM 709, IBM 7090,IBM 7040, UNIVAC 1107, UNIVAC 1108, Philco 210-211, and eventually the IBM S/370 mainframe computers. Developed in 1959 at the University of Michigan by Bernard Galler, Bruce Arden and Robert M. Graham, MAD is a variant of the ALGOL language. TRAC (for Text Reckoning And Compiling) Language is a programming language developed in the early 1960s by Calvin Mooers. It was one of three "first languages" recommended by Ted Nelson in Computer Lib.

13. 1960’s ALGOL 60 was used mostly by research computer scientists in the United States and in Europe. Its use in commercial applications was hindered by the absence of standard input/output facilities in its description and the lack of interest in the language by large computer vendors. ALGOL 60 did however become the standard for the publication of algorithms and had a profound effect on future language development. John Backus developed the Backus normal form method of describing programming languages specifically for ALGOL 58. It was revised and expanded by Peter Naur for ALGOL 60, and at Donald Knuth's suggestion renamed Backus–Naur Form COMIT was the first string processing language (compare SNOBOL, TRAC, and Perl), developed on the IBM 700/7000 series computers by Dr. Victor Yngve and collaborators at MIT from 1957-1965. Starting in 1961, as a result of customer demands, IBM began development of a FORTRAN IV that removed the machine-dependent features of FORTRAN II (such as READ INPUT TAPE), while adding new features such as a LOGICAL data type, logical Boolean expressions and the logical IF statement as an alternative to the arithmetic IF statement. FORTRAN IV was eventually released in 1962

14. 1960’s APL (named after the book A Programming Language) is a programming language developed in the 1960s by Kenneth E. Iverson. Its central datatype is the multidimensional array. It uses a large range of special graphic symbols [8] to represent most operators, leading to very concise code. Simula is a name for two simulation programming languages, Simula I and Simula 67, developed in the 1960s at the Norwegian Computing Center in Oslo, by Ole-Johan Dahl and Kristen Nygaard. Syntactically, it is a fairly faithful superset of ALGOL 60 CPL (from Combined Programming Language and Cambridge Programming Language before that) is a multi-paradigmprogramming language, that was developed in the early 1963s. SNOBOL (StriNg Oriented and symBOlic Language) is a series of computer programming languages developed between 1962 and 1967 at AT&T Bell Laboratories by David J. Farber, Ralph E. Griswold and Ivan P. Polonsky, culminating in SNOBOL4. It was one of a number of text-string- oriented languages developed during the 1950t from most programming languages by having patterns as a first-class data types and 1960s; others included COMIT and TRAC. SNOBOL4 stands apar

15. 1960’s ALGOL 68 (short for ALGOrithmic Language 1968) is an imperative computer programming language that was conceived as a successor to the ALGOL 60 programming language, designed with the goal of a much wider scope of application and more rigorously defined syntax and semantics. JOSS (an acronym for JOHNNIAC* Open Shop System) was one of the very first interactive, time-sharing programming languages. JOSS I, developed by J. Clifford Shaw at RAND was first implemented, in beta form, on the JOHNNIAC computer in May 1963. The full implementation was deployed in January 1964, supporting five terminals and the final version, supporting ten terminals, was deployed in January 1965 Starting in 1961, as a result of customer demands, IBM began development of a FORTRAN IV that removed the machine-dependent features of FORTRAN II (such as READ INPUT TAPE), while adding new features such as a LOGICAL data type, logical Boolean expressions and the logical IF statement as an alternative to the arithmetic IF statement. FORTRAN IV was eventually released in 1962 * John v. Neumann Numerical Integrator and Automatic Computer

16. 1960’s MIMIC, known in capitalized form only, is a former simulation computer language developed 1964 by H. E. Petersen, F. J. Sansom and L. M. Warshawsky of Systems Engineering Group within the Air Force Materiel Command at the Wright-Patterson AFB in Dayton, Ohio, USA. MIMIC is a further development from MIDAS (Modified Integration Digital Analog Simulator), which represented analog computer design. Written completely in FORTRAN but one routine in COMPASS, and ran on Control Data supercomputers, MIMIC is capable of solving much larger simulation models. COWSEL (COntrolled Working SpacE Language) is a programming language designed between 1964 and 1966 by Robin Popplestone. It was based on an RPN form of Lisp combined with some ideas from CPL. PL/I ("Programming Language One", pronounced /piː ɛl wʌn/) is a procedural, imperative computer programming language designed for scientific, engineering, business and systems programming applications. It has been used by various academic, commercial and industrial organizations since it was introduced in the 1964, and continues to be actively used as of 2009.

17. 1960’s BASIC (an acronym for Beginner's All-purpose Symbolic Instruction Code) is a family of general- purpose, high-level programming languages whose design philosophy emphasizes ease of use. In 1964, John G. Kemeny and Thomas E. Kurtz designed the original BASIC language at Dartmouth College in New Hampshire. RPG is a high-level programming language (HLL) for business applications. RPG is an IBM proprietary programming language and its later versions are only available on IBM i or OS/400 based systems. MARK IV is a Fourth-generation programming language that was created by Informatics, Inc. (later, Sterling Software) in the 1960s. Informatics, Inc. took advantage of IBM's decision to unbundle their software; MARK IV was the first "software product to have cumulative sales of $10 million". Speakeasy is a numerical computing interactive environment also featuring an interpreted programming language. It was initially developed for internal use at the Physics Division of Argonne National Laboratory by the theoretical physicist Stanley Cohen. [2] He eventually founded Speakeasy Computing Corporation to make the program available commercially.

18. 1960’s P′′ is a primitive computer programming language created by Corrado Böhm in 1964 to describe a family of Turing machines. IITRAN was a programming language created in the mid-1960s. It was designed as a first language for students, and its syntax resembled that of PL/I. The name derives fromIllinois Institute of Technology, where it was developed. MAD/I has a syntactic structure similar to ALGOL 60 together with important features from the original MAD and from PL/I. MAD/I was designed as an extensible language. TELCOMP was a programming language developed at Bolt, Beranek and Newman (BBN) in about 1964 and in use until at least 1974. BBN offered TELCOMP as a paid service, with first revenue in October 1965. Atlas Autocode (AA) was a programming language developed around 1965 at Manchester University for the Atlas Computer. ("Autocode" was basically an early term for "programming language"; different autocodes could be totally different, unlike, say, different FORTRANs.) It was developed by Tony Brooker and Derrick Morris as a variant of the ALGOL programming language

19. 1960’s JOSS II, was developed by Charles L. Baker, Joseph W. Smith, Irwin D. Greenwald, and G. Edward Bryan for the PDP-6 computer between 1964 and February 1966. 1966 - ALGOL W is a programming language. It was based on a proposal for ALGOL X by Niklaus Wirth and C. A. R. Hoare as a successor to ALGOL 60 in IFIP Working Group 2.1. When the committee decided that the proposal was not a sufficient advance over ALGOL 60, the proposal was published as A contribution to the development of ALGOL. After making small modifications to the language. Wirth supervised a high quality implementation for the IBM/360 at Stanford University that was widely distributed ISWIM is an abstract computer programming language (or a family of programming languages) devised by Peter J. Landin and first described in his article The Next 700 Programming Languages, published in the Communications of the ACM in 1966. The acronymstands for "If you See What I Mean CORAL (Computer On-line Real-time Applications Language) is a programming language originally developed in 1964 at the Royal Radar Establishment (RRE), Malvern, UK, as a subset of JOVIALprogramming languageRoyal Radar EstablishmentMalvernUKsubsetJOVIAL

20. 1960’s BCPL (Basic Combined Programming Language) is a procedural, imperative, and structured computer programming language designed by Martin Richards of the University of Cambridge in 1966. MUMPS (Massachusetts General Hospital Utility Multi-Programming System) or alternatively M, is a general-purpose computer programming language that provides ACID (Atomic, Consistent, Isolated, and Durable) transaction processing. Originally designed in 1966 for the healthcare industry, M continues to be used today by many large hospitals and banks to provide high- throughput transaction data processing Interlisp (also seen with a variety of capitalizations) was a programming environment built around a version of the Lisp programming language. Interlisp development began in 1967 at Bolt, Beranek and Newman in Cambridge, Massachusetts as BBN LISP, which ran on PDP-10 machines running the TENEX operating system. SNOBOL4 stands apart from most programming languages by having patterns as a first-class data type (i.e. a data type whose values can be manipulated in all ways permitted to any other data type in the programming language) and by providing operators for pattern concatenation and alternation. Strings generated during execution can be treated as programs and executed.

21. 1960’s XPL is a programming language based on PL/I, and a portable one-pass compiler written in its own language, and a parser generator tool for easily implementing similar compilers for other languages. XPL was designed in 1967 as a way to teach compiler design principles and as starting point for students to build compilers for their own languages. XPL was designed and implemented by William McKeeman and David B. Wortman at University of California, Santa Cruz and James J. Horning and others at Stanford University. XPL was first announced at the 1968 Fall Joint Computer Conference. The methods and compiler are described in detail in the 1971 textbook A Compiler Generator. DiBOL or Digital's Business Oriented Language is a general- purpose, procedural, imperative programming language, designed for use in Management Information Systems (MIS) software development.

It is a frame-based language. 1975 Compiler Description Language, or CDL, is a programming language based on affix grammars. It is very similar to Backus–Naur form(BNF) notation. It was designed for the development of compilers. It is very limited in its capabilities and control flow; and intentionally so. The benefits of these limitations are twofold.

26. 1970’s Smalltalk is an object-oriented, dynamically typed, reflective programming language. Smalltalk was created as the language to underpin the "new world" of computing exemplified by "human– computer symbiosis. The PL/M programming language (an acronym of Programming Language for Microcomputers) is a high-level language developed by Gary Kildall in 1972 for Intel for its microprocessors. C is a general-purpose, imperative computer programming language, supporting structured programming,lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, and therefore it has found lasting use in applications that had formerly been coded in assembly language, including operating systems, as well as various application software for computers ranging from supercomputers to embedded systems. C was originally developed by Dennis Ritchie between 1969 and 1973 at AT&T Bell Labs and used to re-implement the Unixoperating system.

28. 1970’s GRASS (GRAphics Symbiosis System) was a programming language created to script 2D vector graphics animations. GRASS was similar to BASIC in syntax, but added numerous instructions for specifying 2D object animation, including scaling, translation, rotation and color changes over time PROSE was the mathematical 4GL virtual machine which established the holistic modeling paradigm known as Synthetic Calculus (AKA MetaCalculus). A successor to the SLANG/CUE simulation and optimization language developed at TRW Systems, it was introduced in 1974 on Control Data supercomputers.4GLvirtual machine ABC is an imperative general-purpose programming language and programming environment developed at CWI, Netherlands byLeo Geurts, Lambert Meertens, and Steven Pemberton. It is interactive, structured, high-level, and intended to be used instead of BASIC, Pascal, or AWK. It is not meant to be a systems-programming language but is intended for teaching or prototyping. The language had a major influence on the design of the Python programming language (as a counterexample); Guido van Rossum, who developed Python, previously worked for several years on the ABC system in the early 1980s

29. 1970’s Scheme was created during the 1975s at the MIT AI Lab and released by its developers, Guy L. Steele and Gerald Jay Sussman, via a series of memos now known as the Lambda Papers. It was the first dialect of Lisp to choose lexical scope and the first to require implementations to perform tail-call optimization, giving stronger support for functional programming and associated techniques such as recursive algorithms. Altair BASIC was an interpreter for the BASIC programming language that ran on the MITS Altair 8800 and subsequent S-100 bus computers.

The aim of the language, as expressed by John Chambers, is "to turn ideas into software, quickly and faithfully". The SAS language is a computer programming language used for statistical analysis, originated by a project at the North Carolina State University. It can read in data from common spreadsheets and databases and output the results of statistical analyses. FP (short for Function Programming) is a programming language created by John Backus to support the function-level programming paradigm. This allows eliminating named variables. The Bourne shell (sh) is a shell, or command-line interpreter, for computer operating systems. The Bourne shell was the default Unix shell of Unix Version 7. Most Unix-like systems continue to have /bin/sh—which will be the Bourne shell, or a symbolic link or hard link to a compatible shell even when other shells are used by most users. Developed by Stephen Bourne at Bell Labs, it was a replacement for the Thompson shell, whose executable file had the same name—sh. It was released in 1977 in the Version 7 Unix release distributed to colleges and universities Commodore BASIC, also known as PET BASIC, is the dialect of the BASIC programming language used in Commodore International's 8-bit home computer line, stretching from the PET of 1977 to the C128 of 1985.

It is popular in particular areas of science, such as astronomy, atmospheric physics and medical imaging. Icon(1977) is a very high-level programming language featuring goal directed execution and many facilities for managing strings and textual patterns. It is related to SNOBOL and SL5, string processing languages. Icon is not object-oriented, but an object-oriented extension called Idol was developed in 1996 which eventually became Unicon.
