Avie Tevanian leaves Apple
Avadis "Avie" Tevanian is leaving
. Tevanian has been the primary figure in shaping
Apple's MacOS X operating system. He started his career as a principal
designer and engineer of the Mach kernel at the Carnegie Mellon
University, then joined NeXT in 1988 as an engineer on the NEXTSTEP
operating system team. There, he quickly ascended ranks until he became
manager of the operating system, and finally NeXT's vice president of
engineering in March 1995. He joined Apple in 1997 after the company's
acquisition of NeXT, and led the development of MacOS X, which is still
based on Mach and NEXSTEP to this day. In 2003, Tevanian became Apple's
chief technology officer, while Bertrand Serlet—another long-time
NeXT employee—oversaw development of the OS X 10.4 "Tiger"
release. Apple stated that Tevanian was "leaving the company to pursue
other interests and plans to take some time off in the interim," and that
Apple "thank[ed] him for his many accomplishments."
