Marshall Kirk McKusick is a computer scientist, known for his extensive work on BSD UNIX, from the 1980s to FreeBSD in the present day. He was president of the USENIX Association from 1990 to 1992 and again from 2002 to 2004, and still serves on the board. He is on the editorial board of ACM Queue Magazine. He is known to friends and colleagues as "Kirk".

Gordon Leon Kane is Victor Weisskopf Distinguished University Professor at the University of Michigan and Director Emeritus at the Leinweber Center for Theoretical Physics (LCTP), a leading center for the advancement of theoretical physics. He was director of the LCTP from 2005 to 2011 and Victor Weisskopf Collegiate Professor of Physics from 2002 - 2011. He received the Lilienfeld Prize from the American Physical Society in 2012, and the J. J. Sakurai Prize for Theoretical Particle Physics in 2017.

Silvio Martinello is a retired road bicycle and track cyclist from Italy. He won the gold medal in the men's points race at the 1996 Summer Olympics in Atlanta, Georgia, followed by the bronze medal in the men's madison in Sydney, Australia alongside Marco Villa.

Jürgen Haase is a former track and field athlete and Olympian, who, competing for East Germany, was among the world's best long distance track runners in the 1960s and 1970s. Twice during this period, in 1966 and 1969, he was European champion in the 10,000 meters.

Seiji Ogawa is a Japanese researcher known for discovering the technique that underlies Functional Magnetic Resonance Imaging (fMRI). He is regarded as the father of modern functional brain imaging. He determined that the changes in blood oxygen levels cause its magnetic resonance imaging properties to change, allowing a map of blood, and hence, functional, activity in the brain to be created. This map reflected which neurons of the brain responded with electrochemical signals to mental processes. He was the first scientist who demonstrated that the functional brain imaging is dependent on the oxygenation status of the blood, the BOLD effect. The technique was therefore called Blood oxygenation level-dependent or BOLD contrast. Functional MRI (fMRI) has been used to map the visual, auditory and sensory regions and moving toward higher brain functions such as cognitive functions in the brain.

Franz Keller was a West German nordic combined skier. At the 1968 Winter Olympics in Grenoble, he won the gold medal in the individual event. Keller also won a silver at the 1966 FIS Nordic World Ski Championships in the individual event and won the event at the Holmenkollen ski festival in 1967.
