<i>Enterprise Systems</i> Power 100: 41-50

IT Leaders No. 41-50

41. Anne M. Mulcahy (President & CEO, Xerox Corp.)
Although Xerox's research institutions have done much to change the face of computing, Xerox has rarely made money from key inventions like the mouse or the graphical user interface. As the shifting economy has hit Xerox, research bodies like Xerox PARC have fallen on hard times for the first time. While the computer industry was once based on the academic-style basic research Xerox offered, computer development is now market-driven rather than technology-driven, perhaps making basic research a thing of the past.

42. Vinton G. Cerf (Senior Vice President for Internet Architecture and Technology, WorldCom Inc.; Chairman, Internet Corporation for Assigned Names and Numbers; Co-inventor, TCP/IP)
Since aiding the creation of TCP/IP decades ago, Cerf has remained a leading commentator on the Internet and an exponent of its widespread adoption. Cerf is only the second person to serve as chairman of ICANN, succeeding industry commentator Esther Dyson. As chairman of ICANN, Cerf will lead the body in deciding its approach to adding new top-level domains and resolving intellectual property disputes surrounding domain names.

43. Shawn Fanning (Founder & Creator, Napster Inc.)
Fanning didn't start the MP3 phenomenon, nor did he invent peer-to-peer (besides, Napster isn't really p-to-p), but Fanning melded the two technologies into a single product accessible to the most basic computer users. The implications of Napster have been broad, from bandwidth issues at universities and businesses to intellectual property issues for service providers.

44. Phil Zimmerman (Creator, Pretty Good Privacy [PGP] encryption scheme; Chief Cryptographer, Hush Communications)
Zimmerman's PGP program gave the masses access to strong encryption, allowing the average computer enthusiast to use public-key encryption for the first time. When he posted the code on the Internet, however, he got in trouble with the U.S. government, which accused him of exporting munitions-grade encryption. The government eventually relaxed its controls after public outcry from users and privacy advocates. After Network Associates acquired PGP, Zimmerman left and has turned his attention to Hushmail, which offers a secure, encrypted Hotmail-style e-mail service. Zimmerman's work may enable even the most basic users to have transparent encryption services.

45. Michael Armstrong (Chairman & CEO, AT&T)
Although AT&T fought its initial court-ordered breakup in 1984 tooth and nail, Armstrong is now leading AT&T into a second, voluntary breakup. The company plans to split its four divisions into separately traded companies to adapt to the market faster. Consumer services, business services, wireless and cable will each splinter off into its own organization, serving independent markets.

46. Peter Nevitt (Director of Information Systems, Interpol)
Interpol is the behind-the-scenes international law enforcement agency that shares information and leads to catch criminals worldwide. Because information-sharing is a crucial part of its mandate, Interpol has turned to IT to speed the dissemination of information between members. Nevitt has taken on the task of bringing the organization into the Internet age, adding functionality that increases the effectiveness of the agency. Its database is searched hundreds of times a day by police around the globe.

47. Tom Engibous (Chairman, President & CEO, Texas Instruments Inc.)
While TI doesn't make high-profile chips like Intel's Pentium or AMD's Athlon, its Digital Signal Processors have become critical components in devices from cell phones to MP3 players. As more intelligence becomes embedded in non-computer devices and as small thin clients explode, Texas Instruments is poised to drive a significant amount of change in the computing world.

48. Koji Nishigaki (CEO, NEC Corp.)
Nishigaki leads NEC through a turbulent time as he attempts to reposition the OEM in a tepid Japanese economy and a global PC slowdown. He took the reigns after his predecessor, Hisachi Komeko resigned in the aftermath of a government over-billing scandal. Nishigaki hopes to see NEC traded on the New York markets, spreading its reach throughout the world as both a vendor and a solid investment. The CEO has slashed both staff and budgets, a common move in the U.S., but rare in Japanese business culture.

49. Milo Medin (CTO, Excite)
ISPs have seen a fair amount of trouble in the past year, and Excite has not been spared the hard times. However, in the DSL vs. cable modem race, it appears that Excite@home may be the clear winner. Cable broadband penetration has far outpaced DSL, clicking along as the Baby Bells and competitive local exchange carriers have struggled to upgrade equipment and expand service areas. In contrast, Excite@home has leveraged the cable infrastructure to provide broadband services to cable companies and consumers.

50. Brian Halla (Chairman, President & CEO, National Semiconductor Corp.)
National Semiconductor's systems-on-a-chip integrate sundry components used in electronic devices onto a single unit. While they won't impress anyone with performance, the chips are designed for making small devices smarter. The chips have found their home in mobile phones, embedded systems and consumer electronics, contributing to the process of allowing information to reach us on small devices virtually anywhere.
