Erling Pytte

Erling Pytte died peacefully on the evening of January 30, 2026 at the age of 88. He is survived by his wife Patricia; children, Katherine and her husband Beach Edwards, Carolyn and her husband James Castonguay, and John and Angie Olivar; and his grandchildren, Gillian, John, Simon and Benjamin.

Above all else, it was Erling’s integrity that led to the affection and respect of all who knew him. He grew up on an ancestral farm in Norway, playing soccer when not haying and tending sheep in summer and skiing to a one-room schoolhouse in winter. His father, Ole, was a key figure in the Resistance, leading the parachute drop operation of weapons from England during the Nazi occupation. Erling and his brothers, Peder, Agnar, and Oddvar wore many shirts sewn from parachute silk. At sixteen, Erling received a scholarship to Exeter, worked his passage over on a cargo ship, immediately skipped a grade, and played on the soccer team. He then went on to Princeton, skipped another year, studied physics, and played varsity soccer, culminating in an All-Ivy position. Harvard was next for a doctorate in theoretical physics. There he met his wife Patricia, who remembers that “he radiated goodness,” as well as good looks. After a post-doc at Berkeley, he returned to Norway to continue research and teach at the University of Oslo. By luck he was spotted by the IBM Zurich Research Laboratory, where he spent five happy years. That small physics department would eventually produce four Nobel laureates. During those years, he and Patricia raised three young children while hiking in the Alps extensively, skiing, and still playing soccer. Now with three small children, who were learning Swiss German at an alarming rate, the decision was made to return to the States where they would have roots. Farmers believe in roots.

The family settled in South Salem, New York, in a much-loved 1860 farmhouse where the extended family gathered for several weeks each year. For the next thirty years Erling worked at the Thomas J. Watson Research Center in Yorktown Heights, first doing theoretical research (with pad and pencil in the pre-computer days) primarily in condensed matter physics, then building and leading the theoretical research group. After retiring, having seen his children educated, married and well-employed, Erling turned to new pursuits: investing, civic responsibility rooted in his Scandinavian values, and traveling with great enthusiasm, eventually to fifty-two countries. He also devoted himself to restoring his home and gardens. In many ways he had returned to farm life, rooted in land and family. Throughout his life, Erling was devoted to his family. For them, he was a model of hard work, humility, and goodness.
