Dennis Ritchie is the inventor of C programming language (American Scientist).

Introduction:
C programming language is a high-level procedural language that is widely used for developing operating systems, system software, device drivers, compilers, and other programming languages. It was developed by Dennis Ritchie at Bell Labs in the early 1970s.

Early Life of Dennis Ritchie:
Dennis Ritchie was born on September 9, 1941, in Bronxville, New York. He was a computer scientist who was best known for his work on developing the C programming language and for his contribution to the development of the Unix operating system.

Development of C Programming Language:
In the early 1970s, Dennis Ritchie and his colleagues at Bell Labs were working on developing an operating system called Unix. They needed a programming language that could be used to write system software for the new operating system. The language that they developed was called C.

C was designed to be a high-level procedural language that would be easy to use and would allow programmers to write efficient code. It was also designed to be portable, meaning that it could be used on different types of computers without modification.

Features of C Programming Language:
C programming language is a powerful language that has many features that make it useful for developing system software, device drivers, and other applications. Some of the features of C programming language are:

- Structured programming constructs
- Low-level access to memory
- Bit manipulation
- Pointers
- Modular programming
- Portability
- Dynamic memory allocation

Conclusion:
Dennis Ritchie's contribution to the development of C programming language has been immense. Today, C programming language is used by millions of programmers worldwide and is considered to be one of the most important programming languages ever developed.
