Pieter Cornelis Tobias de Boer, a professor in the Sibley School
of Mechanical and Aerospace Engineering for more than 40
years, died May 2 at Kendal of Ithaca. He was 85.
De Boer’s academic interests included the thermodynamic
analysis and optimal design of pulse-tube cryocoolers, which
emerged in the 1980s and are used in semiconductor fabrication
and other industrial and military applications.
Another area of recent interest was the rupture energy of
pendular rings, with application to the attachment strength of
thin films in microelectromechanical systems (MEMS) devices.
After serving as assistant professor at Maryland from 1962
to 1964, de Boer and his family moved to Ithaca when he was
hired by Cornell as assistant professor in the Graduate School
of Aeronautical Engineering. He was promoted to associate
professor in 1968, and to full professor in 1974, two years after
the formation of the Sibley School of Mechanical and Aerospace
Engineering. De Boer retired in 2000 and was an emeritus
professor in the Sibley School following his retirement.
In addition to his role as professor, de Boer served as associate
director of the Sibley School from 1982 to 1991. He was the
school’s “official or unofficial parliamentarian,” said colleague
and emeritus professor John F. Booker.
Away from academia, De Boer was an avid cyclist, distance
runner, Nordic skier and triathlete, and participated in
orienteering. He was president of the Finger Lakes Cycling
Club, of which Stuart Leigh Phoenix, professor in the Sibley
School, is also a member.
Perhaps de Boer’s most notable athletic achievement: He set
a national age-group record by cycling 448 miles in 24 hours at
He was also founding president of the Cayuga Nordic Ski
Club and treasurer of the Cascadilla Rowing Club.
De Boer is survived by his wife, children and five
