Patrick M. Hanrahan (* 1955 ) is an American computer graphics engineer, professor of computer science and electrical engineering and a doctorate in biophysics from Stanford University . His research focuses on rendering algorithms , graphics processors, and scientific illustration and visualization .

He has received numerous awards, including several Academy Awards and the Turing Award for 2019.


Hanrahan grew up in Green Bay , Wisconsin . He attended the University of Wisconsin – Madison (UW-Madison) and graduated in 1977 with a bachelor's degree in nuclear engineering . There he continued his education and taught a new computer science course in graphics as a doctoral student in 1981. One of his first students was an art student, Donna Cox , who is now known for her art and scientific visualizations. In 1985 , Hanrahan received his PhD in biophysics from UW-Madison. In the 1980s he worked at the New York Institute of Technology , Computer Graphics Laboratory and Digital Equipment Corporation under Edwin Catmull .

Further career

As a founding employee of Pixar Animation Studios , Hanrahan was involved in the development of the RenderMan Interface Specification and the RenderMan Shading Language from 1986 to 1989 . It was part of the credits of the Pixar productions The Magic Egg (1984), Tin Toy (1988) and Toy Story (1995).

In 1989 Hanrahan moved to Princeton University . In 1995 he moved to Stanford University . Hanrahan co-founded Tableau Software in 2003 and has been a senior engineer there ever since. In February 2005, Stanford University was named the US Department of Homeland Security's first regional visualization and analysis center, addressing information visualization and visual analysis issues. In 2011, Intel Research announced funding for a visual computing center jointly run by Intel's Hanrahan and Jim Hurley.

He joined the National Academy of Engineering in 1999 , the American Academy of Arts and Sciences in 2007, and the Association for Computing Machinery in 2008 .


Hanrahan received three Oscar prizes for his work and research in graphic data processing : For RenderMan in 1993. In 2004 he received another Oscar with Stephen R. Marschner and Henrik Wann Jensen for simulations of volume scattering under the surface in translucent materials. In 2014 he received an Oscar along with Matt Pharr and Greg Humphreys an award for their formalization and reference implementation of the concepts of physically based rendering (PBR) described in their book Physically Based Rendering .

Hanrahan received an award from SIGGRAPH in 2003 for his " leadership role in rendering algorithms, graphic architecture and systems, and new visualization methods for computer graphics ".

In 2006 he received the Career Award for visualization research from the Institute of Electrical and Electronics Engineers .

For 2019, Hanrahan and Edwin Catmull received the Turing Award in March 2020 for their pioneering work on Computer Generated Imagery .
