11 Most Influential & Greatest Programmers Of All Time

The other day when I was trying to fix a bug in one of the applications I was working on, I was really frustrated with myself as the fix was really easy (I missed some configuration but for some reason, the logs were not printing the error). I wasted 25 minutes on it. After the code fix, I wondered what if I was sitting with one of the Greatest Programmers of all time (hypothetically), how much time would they have taken to find the root cause.

1 minute?… 30 seconds?… 1 second?

Programming is a skill. It’s an art for some. Some people just code for hours to relieve their stress. While others express their emotions by developing applications. Some create solutions to the most complex problems out there. The fact that ideas can be transitioned to reality via programming always fascinated me.

Here’s a list of the programmers (in no particular order) who pioneered the computing world and changed the way we access information today.

Dennis Ritchie

Dennis MacAlistair Ritchie was an American computer scientist who created the C programming language along with his long-time colleague, Ken Thomson. He is credited for shaping and pioneering the digital era. Today, C programming is used in several software applications, embedded system development, operating systems, and has influenced most modern programming languages.

Richie also co-created the UNIX operating system along with Ken Thomson. For his work, in 1983 he received the Turing Award from the ACM, the Hamming Medal in 1990 from the IEEE and in 1999 the National Medal of Technology from President Clinton. He was the head of Lucent Technologies System Software Research Department when he retired in 2007.

Tim Berners-Lee

James Arthur Gosling is a Canadian computer scientist who is widely known for his creation of the highly successful and commonly used Java programming language in 1994 as well as its original virtual machine and compiler. As of 2019, Java was one of the most popular programming languages in use according to GitHub, particularly for client-server web applications, with a reported 9 million developers.

Gosling has also made major contributions to several other software systems, such as NeWS and Gosling Emacs. Due to his extraordinary achievements, Gosling was elected to Foreign Associate member of the United States National Academy of Engineering. Gosling has won several awards in his life. Some include The Economist Innovation Award in 2002, IEEE John von Neumann Medal in 2015, named a Computer History Museum Fellow for the conception, design, and implementation of the Java programming language in 2019. He was also made an Officer of the Order of Canada in 2007 which is Canada’s second-highest civilian honour.

Kenneth Lane Thompson, or simply “Ken” as he is called by the hacker community, is an American pioneer of computer science. Thompson had designed and implemented the original Unix operating system and also invented the B programming language (the direct predecessor to the famous C programming language), and was one of the early developers of the Plan 9 operating systems. Since 2006, Thompson has also co-invented the Go programming language while working at Google.

Ken’s other contributions included his work on regular expressions, early computer text editors QED and ed, the definition of the UTF-8 encoding, and even his work on computer chess that included the creation of endgame tablebases and the chess machine Belle.

Guido van Rossum

Guido van Rossum is a Dutch computer programmer who is the author of the popular Python programming language that is widely used today. In the Python community, Van Rossum is known as a “Benevolent Dictator For Life” (BDFL), meaning that he continues to oversee the Python development process, making decisions where necessary. Python consistently ranks as one of the most popular programming languages.

From 2005 to December 2012, he worked at Google, where he spent half of his time developing the Python language. In January 2013, he started working for Dropbox. In October 2019, Van Rossum officially retired before coming out of retirement the following year to join Microsoft.

Van Rossum received several awards for his contributions to his work on Python. Some of them include the 2001 Award for the Advancement of Free Software from the Free Software Foundation (FSF) at the 2002 FOSDEM conference in Brussels, the honorary title of Dijkstra Fellow by CWI in 2019, etc.

Jon Skeet is a software engineer known for having the highest reputation on the question-and-answer website Stack Overflow. Skeet joined Stack Overflow in September 2008 after reading about it in a blog post. Skeet became the highest reputation user on the site by December and reached one million in reputation in early 2018. His tenure has made him well-known on the site. He is a C# legend, won the Microsoft MVP award several times and also a Java developer, he actually writes Java at Google. Skeet has written several books, notably C# in Depth, and is the author of the Noda Time C# API. Skeet served on the board of directors of the .NET Foundation from 2019 to 2020.

Skeet has developed a cult following in the developer community because his answers have impacted approximately 333 millions developers. He has actively contributed solutions to problems for C#, Java, and .Net framework.


Well, here are some of the most influential programmers of all time for me. Some other programmers deserve also honourable mention — Ada Lovelace, Bill Gates, Richard Stallman, Niklaus Wirth, Satoshi Nakamoto, John Carmack, Jeff Dean, Drew Houston, Mark Zuckerberg, and Jack Dorsey. I am sure this list would be different for you.

I have also included Jon Skeet in the list even though he didn’t create a programming language or framework but he has helped to build the developer community of what we know today. Also, I have used his solution (from StackOverflow) to fix my configuration change mentioned at the beginning. No wonder Skeet is known as the Chuck Norris of Programming.
