David J. Farber, celebrated Penn professor emeritus and pioneering ‘uncle’ of the internet, has died at 91

David J. Farber, 91, formerly of Landenberg, Chester County, celebrated professor emeritus of telecommunication systems at the University of Pennsylvania, former professor of computer science at Carnegie Mellon University and the University of Delaware, professor at Keio University in Japan, award-winning pioneer in pre-internet computing systems, entrepreneur, and known by colleagues as the “uncle” and “grandfather” of the internet, died Saturday, Feb. 7, of probable heart failure at his home in Tokyo.

A longtime innovator in programming languages and computer networking, Professor Farber taught and collaborated with other internet pioneers in the 1970s, ’80s, and ’90s. He helped design the world’s first electronic switching system in the 1950s and ’60s, and the first operational distributed computer system in the 1970s.

His work on the early Computer Science Network and other distributive systems led directly to the modern internet, and he taught many influential graduate students whom he called the “fathers of the internet.” He was thinking about a World Wide Web, he said in a 2013 video interview, “actually before the internet started.”

“Farber may not be the father of the internet. But he is, at least, its uncle,” Penn English professor Al Filreis told the Daily News in 1998. “Few have paid such close attention for so long to new trends in the information age.”

Colleagues called him “part of the bedrock of the internet” and a “role model for life” in online tributes. Nariman Farvardin, president of the Stevens Institute of Technology in Hoboken, N.J., said: “Professor Farber did not just witness the future, he helped create it.”

In 1996, Wired magazine said Professor Farber had “the technical chops and the public spirit to be the Paul Revere of the Digital Revolution.”

He joined Penn as a professor of computer science and electrical engineering in 1988 and was named the endowed Alfred Fitler Moore professor of telecommunication systems in 1994. He left Penn for Carnegie Mellon in 2003 and joined Keio in 2018.

Gregory Farrington, then dean of Penn’s School of Engineering and Applied Science, told The Inquirer in 1996: “He’s one of the most engaging, imaginative guys who sometimes alternates between great ideas and things that sound nuts. And I love them both. His life is an elaboration on both.”

He was a professor at Delaware from 1977 to 1988 and at the University of California Irvine from 1970 to 1977. Among other things, he created innovative computer software concepts at UC Irvine, studied the early stages of internet commercialization at Delaware, and focused on advanced high-speed networking at Penn. He also directed cyber research laboratories at every school at which he worked.

He earned lifetime achievement awards from the Association for Computing Machinery, the Board of Directors of City Trusts of Philadelphia, and other groups, and was inducted into the Internet Society’s Hall of Fame in 2013 and the Stevens Institute of Technology Hall of Achievement in 2016.

Stevens Institute also created a “societal impact award” in 2003 to honor Professor Farber and his wife, Gloria. “I think the internet has just started,” he said in 2013. “I don’t think we’re anywhere near where it will be in the future. … I look forward to the future.”

Professor Farber earned grants from the National Science Foundation and other organizations. He received patents for two computer innovations in 1994 and earned a dozen appointments to boards and professional groups, and an honorary master’s degree from Penn in 1988.

He advised former President Bill Clinton on science and engineering issues in the 1990s and served a stint in Washington as chief technologist for the Federal Communications Commission. Clinton called him a “pioneer of the internet” in a 1996 shoutout, and Professor Farber testified for the government in a landmark technology monopoly court case against Microsoft Corp.

He championed free speech on the internet, served on technical advisory boards for several companies, and wrote or cowrote hundreds of articles, papers, and reports about computer science.

He was featured and quoted often in The Inquirer and Daily News, and lectured frequently at seminars and conferences in Japan, Europe, Australia, and elsewhere around the world. He wrote an email newsletter about cutting-edge technology that reached 25,000 subscribers in the 1990s, and he liked to show off his belt that held his cell phone, pager, and minicomputer.

He cofounded Caine, Farber, & Gordon Inc. in 1970 to produce software design tools and worked earlier, from 1957 to 1970, on technical staffs for Xerox, the Rand Corp., and Bell Laboratories. In a recent video interview, he gave this advice: “Learn enough about technology so that you know how to deal with the world where it is a technology-driven world. And it’s going to go faster than you ever imagined.”

David Jack Farber was born April 17, 1934, in Jersey City, N.J. Fascinated by gadgets and early computers in the 1940s, he built radios from wartime surplus components as a boy and helped make a unique relay device with a punch card in college. “The card reader was three feet big, but it worked,” he told the Daily News in 1998.

He considered being a cosmologist at first but instead earned a bachelor’s degree in electrical engineering and a master’s degree in math at Stevens.

He met Gloria Gioumousis at Bell Labs, and they married in 1965. They had sons Manny and Joe, and lived in Landenberg from 1977 to 2003. His son Joe died in 2006. His wife died in 2010.

Professor Farber enjoyed iced coffee and loved gadgets. He was positive and outgoing, and he mixed well-known adages into humorous word combinations he called “Farberisms.”

He was an experienced pilot and an avid photographer. In 2012, to honor his son, he established the Joseph M. Farber prize at the Stevens Institute for a graduating senior.

“He was bold,” his son Manny said. “He connected to a lot of people and was close to his friends. He worked on big projects, and it wasn’t just theoretical. He built things that work.”

In addition to his son, Professor Farber is survived by his daughters-in-law, Mei Xu and Carol Hagan, two grandsons, and other relatives.

A memorial service is to be held later.
