Programming Languages Throughout the decades

1970’s
C – It was developed by Dennis Ritchie between 1969 and 1973 at AT&T Bell labs. The development of this language is closely tied to the development of Unix, which was originally implemented by Ritchie and Ken Thompson in assembly language on PDP-7. They decided to port the operating system to a PDP-11. They considered rewriting the operating system using B language. However, B’s inability to take advantage of some of the PDP-11’s features led to the development of C.
Pascal – Published in 1970 and designed by Niklaus Wirth, it was intended as a tool to teach structured programming.

It was started by James Gosling, Mike Sheridan, and Patrick Naughton in 1991 and released in 1995. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another.
Ruby - A dynamic, reflective, object-oriented, general-purpose programming language. It was designed by Yukihiro Matsumoto in the mid 1990’s and released in 1995.
