*David Walden, a computer scientist who helped develop a machine that
would evolve to become the backbone of the internet for decades, died on
April 27 at his home in East Sandwich, Mass. He was 79.*
The cause was complications of mantle cell lymphoma, his wife, Sara
Walden, said.
In 1969, Mr. Walden was part of a small team of talented young engineers
whose mission was to build the Interface Message Processor. Its function
was to switch data among computers linked to the nascent Arpanet, the
precursor to the internet. The first I.M.P. was installed that year at
the University of California, Los Angeles. The I.M.P.s would be crucial
to the internet until the Arpanet was decommissioned in 1989.
