He is a prominent figure in the free software movement and was awarded the FSF Award for the Advancement of Free Software in 2023.

## Biography
- Born: 1965  
- Nationality: German  
- Education: Doctor of Natural Sciences, Karlsruhe Institute of Technology (1996)  
- Known for: Maintaining GNU projects and developing CLISP  
- Employer(s): Karlsruhe Institute of Technology (affiliated)  
- Field(s): Computer science, software engineering  

## Contributions
Bruno Haible has made significant contributions to free software, particularly as a maintainer of several GNU projects. He developed CLISP, a software implementation of the Common Lisp programming language, and has maintained GNU libsigsegv (since 1998), GNU libiconv (since 1999), and GNU libunistring (since 2009). These libraries are widely used in software development for handling signals, character encoding, and Unicode strings, respectively.
