A timeline of the history of programming languages

Which was the first ever programming language created ? Well for your information, it is not C or Pascal but Fortran. Of course, before Fortran, there were a number of other languages such as the assembly language. But Fortran is considered the first major procedural language. In fact, Fortran was created way back in 1954. And till now I thought C was a relatively old language - silly me.

C language or rather the Brian Kernighan and Dennis Ritchie (K&R) C which we learn today is quite new in relation to the history of programming languages and was born in the year 1978 - over 20 years after Fortran and 8 years after Pascal. Btw, did you know that the Linux kernel itself is almost entirely coded in C ?

Fig: A slice of the timeline of programming languages

I came across this awesome timeline of programming languages which tracks the most important computer languages, that gives a fascinating insight into their roots and their development roadmap. The timeline is itself the work of Éric Lévénez which I have covered on this blog some time back. This timeline is by no means complete as it just includes 50 of the more than 2500 documented programming languages but these 50 languages can be considered to be the most important of them.
