Ron Hochsprung—Advice from Illinois Tech Greats

Ronald R. "Ron" Hochsprung (born April 28, 1943) was an early employee and distinguished engineer of Apple. He has been associated with development of the Apple Lisa, Macintosh II, and Thunderbolt.


Hochsprung received a B.S. in computer science from the Illinois Institute of Technology in 1972. He was also a systems manager at the institute's computer center where he co-developed the IITRAN coding language.[1][2]


In 1970, Hochsprung joined the Fermi National Accelerator Laboratory in Batavia, Illinois as a systems programmer.[1]

Apple Computer[]

Hochsprung joined Apple Computer in 1980 as part of the Apple Lisa development team.[3] He became a distinguished engineer in February 1981 and later collaborated with Michael Dhuey as lead system architect of the Macintosh II, which was released in April 1987.[2][4][5] From 1990 to 1992, Hochsprung prototyped cards with Motorola 88100 and IBM RIOS processors for development of what would become the Mac 68k emulator as part of the adoption of the PowerPC architecture at Apple.[6]

As a member of the Institute of Electrical and Electronics Engineers, Hochsprung contributed to hardware standards that became Open Firmware (IEEE-1275) and NuBus (IEEE-1296).[2] Before retiring from Apple in October 2013,[1] one of his last projects was with the team that developed Thunderbolt technology.[2]

After Apple[]

Hochsprung retired to Los Gatos, California and travels extensively with his wife Lynda Bowlin. In March 2014, Hochspring endowed his alma mater, the College of Science at the Illinois Institute of Technology with a gift of US$2 million.[7]
