Biography

John L. Hennessy is an esteemed computer scientist, academic leader, and influential figure in the technology industry. He was born on September 22, 1952, in Huntington, New York, as one of six children. His father worked as an aerospace engineer, and his mother was a teacher who later focused on raising her children.

Hennessy completed his bachelor's degree in electrical engineering at Villanova University. He furthered his education at Stony Brook University, where he obtained both a master's degree and a Doctor of Philosophy in computer science.

Hennessy's career at Stanford University began in 1977 when he joined the faculty. In 1981, he initiated the MIPS project, which aimed to explore the potential of reduced instruction set computer (RISC) processors. Recognizing the commercial viability of the technology developed through his research, he founded MIPS Computer Systems Inc. during his sabbatical year in 1984.

Throughout his tenure at Stanford, Hennessy held several significant positions. He served as the director of Stanford's Computer System Laboratory from 1989 to 1993, leading a research center within the Electrical Engineering and Computer Science departments. He then became the chair of the Department of Computer Science from 1994 to 1996 and subsequently the Dean of the School of Engineering from 1996 to 1999.

In 1999, Hennessy was appointed as the Provost of Stanford University, succeeding Condoleezza Rice. When Stanford President Gerhard Casper stepped down in 2000, Hennessy was chosen as his successor. He assumed the role of President of Stanford University, a position he held until 2016.

Beyond his contributions to Stanford, Hennessy has played prominent roles in various organizations and companies. He served as a board member for Google (later Alphabet Inc.), Cisco Systems, Atheros Communications, and the Gordon and Betty Moore Foundation. In recognition of his accomplishments, Hennessy was elected to the American Philosophical Society in 2008.

Hennessy's dedication to education and research is evident through his involvement in numerous initiatives. He co-founded the Knight-Hennessy Scholars program in 2016, which provides fully funded graduate education at Stanford for exceptional students. As the inaugural director of the program, he oversees its operation and supports scholars from around the world.

In February 2018, Hennessy assumed the role of Chairman of Alphabet Inc., the parent company of Google. In this capacity, he contributes to the strategic direction and governance of one of the world's most influential technology companies.

Hennessy's expertise in computer architecture is widely recognized. He co-authored influential books on the subject, including "Computer Organization and Design: the Hardware/Software Interface" and "Computer Architecture: A Quantitative Approach," written in collaboration with David Patterson. These books have been widely used as educational resources in both graduate and undergraduate courses since 1990.

Hennessy's significant contributions to computer science, particularly his work on RISC architecture, earned him the esteemed Turing Award in 2017. Alongside David Patterson, he was honoured for their pioneering efforts and profound impact on computer chip design.

John L. Hennessy's career and achievements reflect his remarkable contributions to computer science, leadership in academia, and influential role in the technology industry. His dedication to advancing education, research, and innovation has left an indelible mark on Silicon Valley and beyond.
