"Teaching must be measured not by the quality of the exposition but by the learning experience of the students" (Hahn, 2012).

Alexander Hahn is a professor in the Department of Mathematics. Professor Hahn earned his Ph.D. in Mathematics from the University of Notre Dame in 1970. After a year as NSF Postdoctoral Fellow at the University of Zurich and another as SFB Scholar at the University of Bonn, he returned to Notre Dame as a faculty member in 1972. He became Full Professor in 1984, served as Chairman of the Department from 1996 to 2000 and Director of the Kaneb Center from 2002 to 2009. Alex received the Thomas P. Madden Award in 1994.

Professor Hahn's research has a focus on Algebra and Number Theory, in particular the Theory of Forms, Groups, and Algebra. He has written two books and numerous articles on these areas of mathematics. Professor Hahn developed a scholarly interest in the history of science with investigations into the impact of Galileo's experiments with inclined planes on his theory of motion. In 2000, Hahn was appointed to direct the Honors Program of the College of Science. In prior years he developed a two semester calculus sequence for the Arts and Letters students in this program. The subject matter of these courses later grew into a textbook that has the twofold aim of developing the basic elements of calculus from within their historical origins and to illustrate the power of calculus in a wide variety of different contexts of science and economics. Professor Hahn's current research on the connections between elementary mathematics and other disciplines moved him to write a book on the mathematical analysis of building structures.
