Lynn Arthur Steen was born in Chicago and grew up on Staten Island, New York, where his mother sang with the N.Y. City Center Opera and his
father conducted the Wagner College Choir. In 1965, four years after graduating from Luther College in Iowa, Steen completed a Ph.D. in mathematics
at MIT and joined the St. Olaf faculty. He retired in 2009 and is now Professor Emeritus of Mathematics.
Early in his career Steen focused on teaching and developing research experiences for undergraduates. One result was the widely used
reference book Counterexamples in Topology (1970), co-edited with J. Arthur Seebach, Jr. and partly authored by St. Olaf students.
Another was a gradual change in mathematics at St. Olaf from a narrow discipline for the few to an inviting major of value to any liberal arts
graduate. By broadening the major and focusing student work on inquiry and investigation, Steen and his departmental colleagues grew mathematics
into one of the top five majors at the college—and one of the nation's largest undergraduate producers of Ph.D.s in the mathematical
As his teaching led Steen to investigate links between mathematics and other fields, he began writing about new developments in mathematics
for audiences of non-mathematicians. Many of his articles appeared in the weekly magazine Science News and in annual supplements to the
Encyclopedia Britannica. Much of his professional work in the 1970s was devoted to mathematical exposition, the communication of mathematical research to students, teachers, and the broader public.
In the 1980s, Steen helped lead national efforts to modernize the teaching of calculus and other aspects of undergraduate mathematics, serving as editor of the widely cited Calculus for a
New Century: A Pump, not a Filter (1988). During 1985-86 he served as president of the 30,000-member Mathematical Association of America
and in 1989 as chairman of the Council of Scientific Society Presidents. He also served for six years as Secretary of Section A (Mathematics) of
the American Association for the Advancement of Science (AAAS).
At St. Olaf, Steen served as faculty secretary of two special curriculum review committees—the 1972-74 Centennial Long-Range Planning
Committee and the 1988-89 Curriculum Review Committee, each or which proposed major changes to the College's curriculum. In addition, on three
different occasions he led the college's Academic Computing Center and later, the office of Institutional Research and Planning.
Steen's work on collegiate mathematics drew him also into the nascent movement to establish standards for school mathematics. From 1992 through 1995, on leave from St. Olaf, Steen served as executive director of the Mathematical
Sciences Education Board at the National Academy of Sciences in Washington, DC. Subsequently, Steen helped the Washington-based Achieve, Inc.
pioneer grade-by-grade standards intended to simultaneously meet the mathematical requirements of college and career. (The current Common Core
initiative is an evolutionary descendant of those early efforts.) Upon returning to St. Olaf, he began working on special projects
for the Provost’s office.
Steen's work on different sides of the school-college boundary seeded his interest in the imperative of numeracy or quantitative literacy (QL) for active citizens in today's data-driven society. Here
the challenge was not just to help students learn to do mathematics when required or prompted, but to make evidence-based reasoning an ingrained
habit of mind. This work helped stimulate a wide variety of QL programs on campuses around the country and led to the development of the
interdisciplinary National Numeracy Network.
During his career Steen has lectured in over a dozen different countries and is the author or editor of numerous articles and books including
Everybody Counts (1989), Why Numbers Count (1997), Mathematics and Democracy (2001), and Math and Bio 2010
(2005). He is a fellow of the American Association for the Advancement of Science (AAAS) and recipient of four honorary Sc.D. degrees. In 2013
he was elected as a Fellow of the American Mathematical Society.

have two grown daughters, Margaret and Catherine, and six grandsons.
