George “Tom” Harper

George “Tom” Harper

“A college institution” are the words used to describe George “Tom” Harper upon his retirement from Calvin in 1989. He served the college as an English professor for 37 years, from 1952–1989. Following his retirement, he could often be found in the Emeritorium, the room frequented by other Calvin retirees, discussing the issues of the day.

Harper died on May 10, after a brief illness.

During his nearly four-decade tenure he taught courses in Victorian literature and Shakespeare, as well as rhetoric and introduction to literature.

Beyond English, Harper just knew a lot; he regaled others with his detailed accounts of people and places.

“What I most loved about Tom was his extraordinary memory and that every memory opened a cache of stories,” recalled Dean Ward, a former colleague. “Once or twice— when I thought he’d taken some creative license with, say, a story about an old CRC minister—I fact checked him. Turned out that it was his most outrageous stories that were most dead-on accurate.”

Yet, to those who knew him well, Harper was most cherished as a friend.

“He really cared,” said another former colleague Henry Baron. “I loved him for that, and he made me the better for it. I will always be grateful for Tom Harper in my life; I will always miss him.”

Harper is survived by his wife, Elaine; children: Samuel and Karla Harper, Amelia and Clark Griffin, and Katherine and Dan Hawkins; and four our grandchildren.

Jack Kuipers

Jack Kuipers

To know the impact of Jack Kuipers the researcher one need only peruse the reviews on amazon.com of his 1999 book Quaternions and Rotation Sequences: A Primer with Applications to Orbits, Aerospace, and Virtual Reality. Perhaps the title alone is signal enough of Kuiper’s deep intellect, but the book’s reviews speak of both its remarkable depth and also its accessibility.

Those who knew Kuipers the researcher and Kuipers the teacher recognized his abilities, including his colleagues at Calvin, from which he retired in 1986 after a distinguished career as a professor of mathematics.

Kuipers died on April 27 at the age of 95.

After graduating from Calvin, and after a stint serving his country in the European theater, he worked for almost 20 years in industrial engineering, including developing complex weapons systems for the U.S. Air Force during the Cold War.

His work in the 1950s led many to consider Kuipers the father of virtual reality. During that decade he began experimenting with the mathematics used to produce simulations for air force pilots, developing a six-dimensional graphics system, which became widely used in the aerospace, defense and entertainment industries.

“Much as he loved a good discussion on deep issues,” said Calvin dean and mathematician Mike Stob, “he was very careful to express his opinions tentatively, if at all. He was unfailingly charitable to the views of others.”

Kuipers is survived by his wife, Lois; children: Benjamin and Laura Lein Kuipers, Emily and James Akerson, Joel and Terry Murphy Kuipers, Alison Kuipers, and Lynne and David Eggert; and 11 grandchildren.
