Mr. Walden eventually enrolled at San Francisco State College (now a university) and received his bachelor’s degree in mathematics in 1964. His interest in computing grew from a course he took in numerical analysis, which involved working on an IBM computer.
After college, he went to work at the Lincoln Laboratories at the Massachusetts Institute of Technology as a computer programmer in the Space Communications Division.
In 1965, he met Sara Elizabeth Cowles, an education manager, and they married the following year. He was hired in 1967 at Bolt Baranack and Newman. Shortly afterwards, the company won the contract to build the first IMP.
Mr. Walden stated in a 1990 interview with the Charles Babbage Institute at the University of Minnesota, an archive and research center specializing in information technology.
“We were in and out of each other’s offices and helped debug each other,” he added.
Every discovery was exciting. “We’ll run and say, ‘Look, I ran this!'” He said.
Mr. Walden left Bolt Beranકek for a year in 1970 to work at Norsk Data, which helped the company build a computer modeled after IMP. He returned to Bolt Baranac in 1971 and remained there until 1995. He later became an expert in the field of management. An avid computer historian, he was the editor of the IEEE Annals of the History of Computing, which was originally published by the Institute of Electrical and Electronics Engineers.
Although he did not have an advanced degree, Mr. Walden received an honorary doctorate in 2014 from California State University for his work on ARPANET. “He commented to me on more than one occasion that he never thought he would receive this kind of honor,” said Alex Mackenzie, a former colleague of Mr. Waldense, said in an interview.
In addition to his wife, Shri. Walden is survived by his son Luke; His brother, Daniel; His sister, Velma Walden Hampson; And two grandchildren.
