Education and career
John Wharton grew up in Neenah, Wisconsin, graduating from Neenah High School in 1972. He graduated from Northwestern University with a bachelor's degree in electrical engineering in 1976 and a master's degree in computer science in 1977, having earlier attended Yale University for two years before transferring to Northwestern.[3] He was hired by Intel at the instigation of Tom Rolander,[4] working there for 5 years before leaving to start his consulting company, Applications Research.[3] He was a founding member of the editorial board of Microprocessor Report.[5] He first spoke at the Asilomar Microcomputer Workshop in 1980, along with Carver Mead, Jim Clark, Dave Patterson and Gary Kildall.[6] He first chaired a session in 1983, and became chair of the workshop in 1985, a position he continued to hold through 1997. He was Program Chair from 1999 through 2017.[6] From 1989 to 2004, with Dennis Allison, he coordinated Stanford University's EE380 course.[7]
J. H. Wharton was the architect of the instruction set of the Intel MCS-51,[3] commonly known as the 8051. The MCS-51 and its derivatives are Intel's highest volume microprocessor,[8] and among the most implemented instruction set architectures of all time.[2][3]
Wharton was the subject of a 1999 New York Times profile,[8] and a 2001 article about his trips to Fiji to collect debris from the deorbit of the Mir space station.[9] In 1996 he appeared on Late Night with David Letterman.[8][10] His friends have created a memorial Web site.[11]
