Andrew Stuart “Andy” Tanenbaum (sometimes referred to by the handle ast) (born March 16, 1944) is a professor of computer science at the Vrije Universiteit, Amsterdam in the Netherlands. He is best known as the author of MINIX, a free Unix-like operating system for teaching purposes, and for his computer science textbooks, regarded as standard texts in the field. He regards his teaching job as his most important work.Andrew Tanenbaum is best known for his work on computer architecture, operating systems, and networks.

ImageAndrew Stuart Tanenbaum was born in New York  and grew up in White Plains, New York, where he attended the local high school. His undergraduate degree was obtained at the Massachusetts Institute of Technology (MIT) in 1965 and his Ph.D. came from the University of California at Berkeley in 1971. Both degrees were in computer science. During his undergraduate period Tanenbaum spent a summer working at IBM, and this experience put him off working in industry for the rest of his life. For his postdoctoral studies Tanenbaum went to Amsterdam, where he has remained ever since. His postdoctoral studies were carried out jointly at Mathematisch Centrum and Vrije Universiteit between 1971 and 1973. In 1973 he took a permanent position at Vrije Universiteit where he rose to the position of professor of computer.He moved to the Netherlands to live with his wife, who is Dutch, but he retains his United States citizenship. He teaches courses about Computer Organization and Operating Systems and supervises the work of Ph.D. candidates at the VU University Amsterdam.

Prof. Tanenbaum is the principal designer of three operating systems: Amoeba, MINIX, and Globe. Amoeba is a distributed operating systems for SUN, VAX, and similar workstation computers. MINIX is a small operating system designed for high reliability and embedded applications as well as for teaching. Globe is a distributed operating system.

The Netherlands, where he heads the Computer Systems Group. He is also Dean of the Advanced School for Computing and Imaging, an interuniversity graduate school doing research on advanced parallel, distributed, and imaging systems. Nevertheless, he is trying very hard to avoid turning into a bureaucrat.
In the past, he has done research on compilers, operating systems, networking, and local-area distributed systems. His current research focuses primarily on the design of wide-area distributed systems that scale to a billion users. These research projects have led to five books and over 85 refereed papers in journals and conference proceedings.
He has also produced a considerable volume of software. He was the principal architect of the Amsterdam Compiler Kit, a widely-used toolkit for writing portable compilers, as well as of MINIX, a small UNIX clone intended for use in student programming labs. Together with his Ph.D. students and programmers, he helped design the Amoeba distributed operating system, a high-performance microkernel-based distributed operating system. The MINIX and Amoeba systems are now available for free via the Internet.
He is a Fellow of the ACM, a Fellow of the IEEE, a member of the Royal Netherlands Academy of Arts and Sciences, winner of the 1994 ACM Karl V. Karlstrom Outstanding Educator Award, and winner of the 1997 ACM/SIGCSE Award for Outstanding Contributions to Computer Science Education. In 2006 he was awarded the IEEE James H. Mulligan, Jr. medal for outstanding contributions to computer education. He is also listed in Who’s Who in the World. His home page on the World Wide Web can be found at

He is well recognized for his texts on computer science, which are famous as standard texts in the field, particularly:
Computer Networks, ISBN 0-13-066102-3
Operating Systems: Design and Implementation, (co-authored with Albert Woodhull), ISBN 0-13-142938-8
Modern Operating Systems, ISBN 0-13-031358-0
Distributed Operating Systems, ISBN 0-13-219908-4

In addition, Tanenbaum is the author or coauthor of five books:

“Distributed Systems” (with Maarten van Steen)
“Modern Operating Systems”
  “Structured Computer Organization”
 “Operating Systems: Design and Implementation” (with Albert S. Woodhull)
 “Computer Networks”

These books have been translated into 20 languages and are used all over the world. Tanenbaum has also published more than 125 refereed papers on a variety of subjects and has lectured in a dozen countries on many topics.

    Minix was the inspiration for the Linux kernel.Tanenbaum became involved in a famous Usenet discussion in 1992 with Linus Torvalds, Linux’s creator, about the merits of Linux’s basic approach using a monolithic kernel instead of the microkernel-based designs that Tanenbaum believed were the way of the future.
