John LeRoy Hennessy (born September 22, 1952) is an American computer scientist, academician, and businessman. Hennessy is one of the founders of MIPS Computer Systems Inc. as well as Atheros and is the tenth President of Stanford University. Marc Andreessen called him "the godfather of Silicon Valley".
Early life and career
He earned his bachelor's degree in electrical engineering from Villanova University, and his master's degree and Ph.D. in computer science from Stony Brook University. He is married to his high school sweetheart, Andrea Berti.
Hennessy became a Stanford faculty member in 1977. In 1984, he used his sabbatical year to found MIPS Computer Systems Inc. to commercialize his research in RISC processors. In 1987, he became the Willard and Inez Kerr Bell Endowed Professor of Electrical Engineering and Computer Science.
Hennessy served as director of Stanford's Computer System Laboratory (1989–93), a research center run by Stanford's Electrical Engineering and Computer Science departments. He was chair of the Department of Computer Science (1994–96) and Dean of the School of Engineering (1996–99).
In 1999, Stanford President Gerhard Casper appointed Hennessy to succeed Condoleezza Rice as Provost of Stanford University. When Casper stepped down to focus on teaching in 2000, the Stanford Board of Trustees named Hennessy to succeed Casper as president. In 2008, Hennessy earned a salary of $1,091,589 ($702,771 base salary, $259,592 deferred benefits, $129,226 non-tax benefits), the 23rd highest among all American university presidents.
In 2007, he was made a Fellow of the Computer History Museum "for fundamental contributions to engineering education, advances in computer architecture, and the integration of leading-edge research with education".
In December 2010, Hennessy coauthored an editorial with Harvard University President Drew Gilpin Faust urging the passage of the DREAM Act; the legislation did not pass the 111th United States Congress.
In 2012, Hennessy was awarded the IEEE Medal of Honor. The IEEE awarded Hennessy their highest recognition "for pioneering the RISC processor architecture and for leadership in computer engineering and higher education". In 2012, Hennessy received an honorary doctor of mathematics degree from the University of Waterloo (Canada), in celebration of his profound contributions to modern computer architecture and to post-secondary education.
Hennessy has a history of strong interest and involvement in college-level computer education. He co-authored, with David A. Patterson, two well-known books on computer architecture, Computer Organization and Design: the Hardware/Software Interface and Computer Architecture: A Quantitative Approach, which introduced the DLX RISC architecture. They have been widely used as textbooks for graduate and undergraduate courses since 1990.
Hennessy also contributed to updating Donald Knuth's MIX processor to the MMIX. Both are model computers used in Knuth's classic series, The Art of Computer Programming. MMIX is Knuth's DLX equivalent.
