Early life and education

Walden was born on June 7, 1942, to Velva (née Diede) and Clarence Walden in

computer, the university's only computer.[1][2][3]

Walden started his career working as a

Bolt Beranek & Newman (BBN) in 1967. It was here that he was part of the seven-member engineering team that developed the packet switching technology that powered the ARPANET, one of the first general purpose computer networks that was a precursor of the modern internet. During his time at BBN, the group of engineers developed the Interface Message Processor, that formed the packet switching basis for the network, developed the hardware, wrote the software, and even acted as the Network Operations Center for the network.[4] Specifically, Walden's efforts focused on developing the packet switching and routing software for the IMP.[5] Walden briefly moved to Norway to work at Norsk Data Elektronikk in Oslo, developing the LFK network, a Norwegian packet switching network, between 1970 and 1971, before returning to the United States to continue working with BBN.[4] Walden was the system architect and Norsk Data's project manager in building out this network.[6][7]

Toward the latter part of his career, Walden focused on

TeX Users Group and contributed to content related to digital typesetting and publishing.[4][8] He had also served as the group's director and treasurer.[9] Walden received a honorary doctorate from the San Francisco State University in 2014, for his contributions to the ARPANET.[1] Walden was the co-founder of Center for Quality of Management and a contributor to IEEE Computer Society's Annals of the History of Computing and a member of its History Committee.[3]

Personal life

Walden married Sara Elizabeth Cowles, an educational administrator, in 1966. The couple had a son. Walden died of mantle cell lymphoma at his house in East Sandwich, Massachusetts, on April 27, 2022. He was aged 79.[1]
