The first programming language

Did you know that the first programming language was invented way back in 1843? Ada Lovelace came up with the first-ever machine algorithm for an early computing machine that she wrote down on a piece of paper because no computers existed at the time! Officially, the first programming language for a computer was Plankalkül, developed by Konrad Zuse for the Z3 between 1943 and 1945. However, it was not implemented until 1998.

History of programming languages: A timeline

Listed below is a timeline of the history of programming languages. The first known programming languages were complicated machine codes that were manually inputted into early computing machines. As you’ll discover, computer programming developed quickly from machine codes to fully automated human-readable code.

1843: Ada Lovelace’s machine algorithm

Ada Lovelace invents the first-ever machine algorithm for Charles Babbage’s Difference Machine that lays the foundation for all programming languages.

1944-45: Plankalkül

Somewhere between 1944-45, Konrad Zuse developed the first ‘real’ programming language called Plankalkül (Plan Calculus). Zeus’s language (among other things) allowed for the creations of procedures, which stored chunks of code that could be invoked over and over to perform routine operations.

1949: Assembly Language

Assembly language was used in the Electronic Delay Storage Automatic Calculator (EDSAC). Assembly language was a type of low-level programming language that simplified the language of machine code. In other words, the specific instructions necessary to operate a computer.

1949: Shortcode

Shortcode (or Short-order code), was the first High-Level Language (HLL) suggested by John McCauley in 1949. However, it was William Schmitt who implemented it for the BINAC computer the same year and for the UNIVAC in 1950.

1952: Autocode

Autocode was a general term used for a family of programming languages. First developed by Alick Glennie for the Mark 1 computer at the University of Manchester, Autocode was the first-ever compiled language to be implemented meaning that it can be translated directly into machine code using a program called a compiler. Autocode was used on the Ferranti Pegasus and Sirius early computing machines in addition to the Mark 1.


FORmula TRANslation or FORTRAN was created by John Backus and is considered to be the oldest programming language in use today. The programming language was created for high-level scientific, mathematical, and statistical computations. FORTRAN is still in use today in some of the world’s most advanced supercomputers.

1958: ALGOL (Algorithmic Language)

Algorithmic language or ALGOL was created by a joint committee of American and European computer scientists. ALGOL served as the starting point for the development of some of the most important programming languages including Pascal, C, C++, and Java.

1958: LISP (List Processor)

List processor or LISP was invented by John McCarthy at the Massachusetts Institute of Technology (MIT). Originally purposed for artificial intelligence, LISP is one of the oldest programming languages still in use today and can be used in the place of Ruby or Python. Companies such as Acceleration, Boeing, and Genworks are still using LISP in their tech stacks.

1959: COBOL (Common Business Oriented Language)

Common Business Oriented Language (COBOL), is the programming language behind many credit card processors, ATMs, telephone and cell calls, hospital signals, and traffic signals systems (just to name a few). The development of the language was led by Dr. Grace Murray Hopper and was designed so that it could run on all brands and types of computers. COBOL is still used to this day primarily for banking systems.

1964: BASIC (Beginner’s All-Purpose Symbolic Instruction Code)

Beginners All-Purpose Symbolic Instruction Code or BASIC was developed by a group of students at Dartmouth College. The language was written for students who did not have a strong understanding of mathematics or computers. The language was developed further by Microsoft founders Bill Gates and Paul Allen and became the first marketable product of the company.

1970: PASCAL

Named after the French mathematician Blaise Pascal, Niklaus Wirth developed the programming language in his honor. It was developed as a learning tool for computer programming which meant it was easy to learn. It was favored by Apple in the company’s early days, because of its ease of use and power.

1972: Smalltalk

Developed at the Xerox Palo Alto Research Centre by Alan Kay, Adele Goldberg, and Dan Ingalls, Smalltalk allowed for computer programmers to modify code on the fly. It introduced a variety of programming language aspects that are visible languages of today such as Python, Java, and Ruby. Companies such as Leafly, Logitech, and CrowdStrike state they use Smalltalk in their tech stacks.

1972: C

Developed by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system. It was called C because it was based on an earlier language called ‘B’. Many of the current leading languages are derivatives of C including; C#, Java, JavaScript, Perl, PHP, and Python. It also has been/still being used by huge companies like Google, Facebook, and Apple.

1972: SQL (SEQUEL at the time)

SQL was first developed by IBM researchers Raymond Boyce and Donald Chamberlain. SEQUEL (as it was referred to at the time), is used for viewing and changing information that is stored in databases. Nowadays the language is an acronym – SQL, which stands for Structured Query Language. There are a plethora of companies that use SQL and some of them include Microsoft and Accenture.

1980/81: Ada

Ada was originally designed by a team led by Jean Ichbiah of CUU Honeywell Bull under contract to the United States Department of Defense. Named after the mid-19th-century mathematician Ada Lovelace, Ada is a structured, statically typed, imperative, wide-spectrum, and object-oriented high-level programming language. Ada was extended from other popular programming languages at the time such as Pascal. Ada is used for air-traffic management systems in countries such as Australia, Belgium, and Germany as well as a host of other transport and space projects.

1983: C++

Bjarne Stroustrup modified the C language at the Bell Labs, C++ is an extension of C with enhancements such as classes, virtual functions, and templates. It has been listed in the top 10 programming languages since 1986 and received Hall of Fame status in 2003. C++ is used in MS Office, Adobe Photoshop, game engines, and other high-performance software.

1983: Objective-C

Developed by Brad Cox and Tom Love, Objective-C is the main programming language used to write software for macOS and iOS, Apple’s operating systems.

1987: Perl

Perl was created by Larry Wall and is a general-purpose, high-level programming language. It was originally designed as a scripting language designed for text editing but nowadays it’s widely used for many purposes such as CGI, database applications, system administration, network programming, and graphic programming.

1990: Haskell

Haskell is a general-purpose programming language named after the American logician and mathematician Haskell Brooks Curry. It is a purely functional programming language meaning it’s primarily mathematical. It’s used across multiple industries particularly those that deal with complicated calculations, records, and number-crunching. Like many other programming languages from this era, it is not overly common to see Haskell in use for well-known applications. With that said, the programming language has been used to write a number of games one of which is Nikki and the Robots.

1991: Python

Named after the British comedy troupe ‘Monty Python’, Python was developed by Guido Van Rossum. It is a general-purpose, high-level programming language created to support a variety of programming styles and be fun to use (a number of the tutorials, samples, and instructions often contain Monty Python references). Python is, to this day, one of the most popular programming languages in the world is used by companies such as Google, yahoo, and Spotify.

1991: Visual Basic

Developed by Microsoft, Visual Basic allows programmers to utilize a drag-and-drop style of choosing and changing pre-selected chunks of code through a graphical user interface (GUI). The language is not overly used these days however Microsoft has used portions Visual Basic to a number of their applications like Word, Excel, and Access.

1993: Ruby

Created by Yukihiro Matsumoto, Ruby is an interpreted high-level programming language. A teaching language which was influenced by Perl, Ada, Lisp, and Smalltalk – among others. Ruby’s primary uses are for web applications development and Ruby on Rails. Twitter, Hulu, and Groupon are some well-known examples of companies that use Ruby.

1995: Java

Java is a general-purpose, high-level language created by James Gosling for an interactive TV project. It has cross-platform functionality and is consistently among the top of the world’s most popular programming languages. Java can be found everywhere, from computers to smartphones to parking meters.

1995: PHP

Formerly known as ‘Personal Home Page’ which now stands for ‘Hypertext Preprocessor’, PHP was developed by Rasmus Lerdorf. Its primary uses include building and maintaining dynamic web pages, as well as server-side development. Some of the biggest companies from across the globe use PHP including Facebook, Wikipedia, Digg, WordPress, and Joomla.

1995: JavaScript

Not all programming languages last forever. Whether it’s a result of developments in technology or simply being replaced by a more sophisticated language. With that said, there are some old programming languages that are still being used by IT professionals today:


The initial version of FORTRAN was proposed at IBM by John Backus way back in 1953. It was the first optimizer compiler and was widely used for scientific work because it’s optimized code competed favorably with hand-written assembly code. The language is still used to this day on some of the world’s fastest supercomputers. There have been a string of updates since 1953 with the most recent version released in 2018.


COBOL was developed back in 1959 and was one of the first high-level programming languages. Despite being invented so long ago COBOL is still hugely prevalent today. In the US alone, 43% of banking systems are built on COBOL, accounting for 95% of ATM swipes, and 80% of in-person transactions.

What is the most popular programming language today?

We’re nearing the end of our journey through the history of programming languages. As you’ve seen, computer programming has developed to a level beyond all expectations, powering the technology that we rely on a daily basis. It’s for this reason that we need skilled professionals to implement and control the programming languages that power the world today.

But which programming language is the most popular?

As you can see above, JavaScript was the most popular language tested on DevSkiller based on the test invites that were sent out. This finding is confirmed in the 2020 Stack Overflow Developer Survey which lists JavaScript as the most popular programming language for the eighth year in a row. SQL, Java, HTML/CSS, and .NET/C# rounded out the top 5 in our results.

The history of programming languages is fascinating. Who would have thought that an algorithm from the mid-19th century would pave the way for the technology-driven society we live in today. From early machine codes to the sophisticated human-readable code that powers our favorite technologies today, programming languages have come a long way. What’s for certain, computer programming will continue to develop as it has done for the past 150 years and it’s exciting to see what the future brings.
