Geoffrey S. Goodfellow (born 1956 in California) is an American entrepreneur associated with early wireless email ventures.[1]

Technology career

[edit]

In 1982 he posted a message titled "Electronic Mail for People on the Move" in an ARPANET mailing list called Telecom Digest.[2] In the early 1990s Goodfellow attempted to commercialize this concept in a product called RadioMail. In 1992, Radiomail entered into a partnership with Research in Motion, RAM Mobile Data, and Ericsson. Goodfellow left the company in 1996.

Goodfellow, a contributor to the Jargon File and participant in the early days of the Silicon Valley computer culture, did not believe in patenting his idea. He told The New York Times, "You don't patent the obvious...The way you compete is to build something that is faster, better, cheaper. You don't lock your ideas up in a patent and rest on your laurels."[1][3]

The inventor, Thomas J. Campana Jr., was granted several patents covering his inventions related to the practical implementation of wireless e-mail. In 2006, after a protracted legal battle, (See NTP Inc.) Research in Motion had to pay $US 615 million to obtain rights to these patents.

In 2006 Goodfellow began researching the cause, nature and origin of what he regards as the critical state of disharmony on the planet.[4]

Geoff Goodfellow is an American computer scientist and entrepreneur renowned for conceiving the idea of wireless email in 1982, enabling electronic messages from to be relayed to , and later founding Anterior Technology in 1988 (renamed RadioMail Corporation) to commercialize wireless messaging services. As a teenager, he gained access to SRI International's computers connected to ARPANET, the internet's predecessor, and contributed to early networking efforts there during the 1970s and 1980s, including testimony on computer security and telecommunications before congressional bodies. Goodfellow also engaged with nascent hacker culture, appearing in influential glossaries like through references to his innovations and personal quirks, such as his vehicle's license plate inspiring the term "jfcl." His work bridged academic research and commercial applications, though he notably eschewed patents for wireless email, forgoing potential billions in later industry settlements.

Early Networking Career

SRI International Role

Geoff Goodfellow served as a staff member in the Computer Science Laboratory at SRI International in Menlo Park, California, beginning in the early 1970s. Initially hired as a teenager, he contributed to research efforts during this period. At SRI, Goodfellow specialized in computer security and networking protocols as a senior research staff member. His work focused on enhancing secure data transmission and protocol development within early networked environments. In January 1983, Goodfellow was assigned for the Metagram Relay as documented in RFC 820, a protocol designated for relay functions to facilitate message routing and transfer across networks, enhancing ARPANET message routing. This assignment underscored his involvement in standardizing networking ports for reliable relay operations.

ARPANET Contributions

The process, originating in the era, facilitated the creation of foundational protocols still in use, such as those for text transmission and early systems. At SRI's AI laboratory during the 1970s, Goodfellow engaged directly with host systems like the , providing firsthand insights into operational constraints such as CPU overload from high-speed serial lines and terminal baud rates exceeding 2400, which limited network expansions. He clarified historical details on early applications, including skepticism over MazeWar's purported major load on the ARPANET due to low-bandwidth connections at sites like SU-AI, and recounted 's prohibition of non-standard services such as the NCP port 21 Limerick Server. Goodfellow's research at SRI from the early 1970s encompassed packet-switched communication systems, drawing on 's innovation in linking heterogeneous computers through . His contributions extended to pre-Internet networking security, serving as Principal Investigator for SRI's -funded efforts in secure packet network protocols.

Wireless Innovations

Invention of Wireless Email

Geoff Goodfellow conceptualized wireless email in 1982 as a system for relaying electronic mail messages from to via radio frequencies, enabling portable access to email without wired connections. He detailed this approach in a posting to an ARPANET mailing list, outlining the transfer of email content to radio-based paging devices for real-time delivery. Key technical challenges included adapting email formats to the one-way, low-bandwidth constraints of paging radio frequencies, including reliable message truncation within the limitations of early mobile radio infrastructure. This innovation laid the groundwork for subsequent wireless email services.

RadioMail Corporation

Geoff Goodfellow founded Anterior Technology in 1988 to commercialize wireless email services, later renaming it RadioMail Corporation, and served as its chairman and chief executive officer. The company specialized in wireless email delivery services, enabling mobile access to over radio networks and positioning itself as an early commercial provider of Internet-based wireless messaging. RadioMail operated without patents on its core wireless email innovations, a decision aligned with Goodfellow's open philosophy that later drew attention amid broader industry patent disputes. Goodfellow left the company in 1996 and Silicon Valley by 1999, expressing disillusionment with the region's culture in personal reflections that highlighted his departure to pursue life abroad.

Publications and Lexical Work

The Hacker's Dictionary

The Hacker's Dictionary: A Guide to the World of Computer Wizards is a 1983 publication by Harper & Row that compiled and annotated early hacker slang and terminology. The book, edited primarily by alongside contributors including Donald R. Woods, Raphael A. Finkel, Mark R. Crispin, and , represented the first printed edition derived from the . Goodfellow contributed to the underlying Jargon File, with entries referencing his innovations and personal quirks, such as his vehicle's license plate inspiring the term "jfcl," helping capture the culture and lexicon of computer enthusiasts at institutions like SRI International and . This work helped standardize and disseminate hacker vocabulary beyond elite circles, influencing the perception of computing subcultures in the 1980s. The 96-page volume, bearing ISBN 0-06-091082-8, marked an early effort to archive ephemeral slang, with subsequent editions evolving separately but building on its foundational entries.

Jargon File Contributions

Geoff Goodfellow contributed to revisions of the , an evolving online repository of hacker slang maintained by communities at institutions such as the , Stanford AI Lab, and SRI International during the late 1970s and early 1980s. His inputs helped refine entries drawn from -era technical cultures, including terms like "gas" and "gaseous," which originated in his usage at SRI to describe outdated or worthless software deserving removal. These contributions occurred alongside those from figures like and early editors Raphael Finkel, Don Woods, and Mark Crispin, emphasizing the file's collaborative nature. Unlike static published compilations, the functioned as a living document, enabling real-time updates and dissemination via , which amplified its role in documenting hacker lexicon beyond printed formats. Goodfellow's involvement, tied to his SRI work, helped propagate SRI-specific slang into broader hacker discourse, fostering a shared vocabulary that influenced subsequent cultural artifacts in computing. This dynamic preservation effort in the early 1980s laid groundwork for enduring glossaries by capturing ephemeral terminology from nascent network environments.

Public Testimonies

1983 Congressional Testimony

In 1983, Geoff Goodfellow testified before the U.S. House of Representatives Subcommittee on Transportation, Aviation and Materials on the topic of , drawing on his decade of experience at SRI International's Computer Science Laboratory where he worked on , protocols, and as for a program. The hearing addressed growing concerns over unauthorized access to computer systems amid expanding telecommunications infrastructure, with Goodfellow highlighting how basic tools like and publicly available information enabled penetrations. Goodfellow emphasized systemic vulnerabilities, noting that many breaches stemmed from inadequate protections such as like the username and password "test," which he described as an implicit invitation to intruders, and the failure to log or disconnect after repeated access attempts. He distinguished between motivated by curiosity and learning—who could improve systems—and malicious "electronic vandals" driven by challenges to authority. Leveraging his own history of , including involvement and prior system penetrations that led to security enhancements, Goodfellow advocated befriending capable intruders to harness their insights rather than solely punishing them. On privacy risks, Goodfellow argued that unauthorized access granted "carte blanche" to sensitive data, allowing reading, alteration, or override of information and software, akin to lapses in handling classified materials at the . He recommended prudent measures like enforcing , to mitigate breaches, modem controls, and access restrictions based on clearance and , while urging clearer federal and state laws to prosecute violations without stifling innovation. These points underscored shared responsibility among users and administrators to safeguard privacy in interconnected systems.

1993 Congressional Testimony

In 1993, Geoff Goodfellow testified before the House Subcommittee on Telecommunications and Finance during hearings on H.R. 707, the Emerging Telecommunications Technologies Act of 1993, which sought to establish procedures for improving the allocation and assignment of the . As Chairman of RadioMail Corporation, he drew on his pioneering work in wireless email to highlight rapid advancements in wireless technologies and the need for efficient spectrum management to enable their deployment. Goodfellow advocated for reforms in spectrum procedures, including competitive bidding mechanisms, to promote innovation while avoiding inefficient traditional assignment methods.
