Craig Barrett will conclude more than 30 years of service at Intel Corp. when he retires from active management and his role as chairman in May at the companys annual stockholders meeting, the Santa Clara, Calif.-based chipmaker announced Friday. He joined Intel in 1975 and has served in many roles, including that of CEO from 1998 to 2005. In recent years, Barrett has been active in Intel's World Ahead Program bringing information technology to emerging economies, and has been active in issues as far ranging as education, health care and U.S. competitiveness. He is currently chair of the U.N. Global Alliance for Information and Communications Technology and Development. "I want to thank Craig for his 35 years of tireless efforts on behalf of Intel," said Paul Otellini, Intel president and CEO, in a press statement. His legacy spans the creation of the best semiconductor manufacturing machine in the world, leading Intel for seven years as we emerged into a global powerhouse, and most recently as our industry's senior statesman and ambassador who has advocated the benefits of education and technology as forces for positive change. Independent director Jane Shaw, who joined Intels board in 1993, will replace Barrett as non-executive chairman. Shaw retired in June 2005 from the position of chairman and CEO of Aerogen.
