David Pengelley is professor emeritus at New Mexico State University, and courtesy faculty at Oregon State University. His research is in algebraic topology and history of mathematics. For several decades he has also collaborated on NSF-funded programs developing pedagogies and materials for teaching with student projects and with primary historical sources, in both traditional undergraduate courses and specially created honors courses. David dreams and advocates that all students, in all courses, could benefit by learning mathematics from studying primary historical sources. He has coauthored three books, on student projects in calculus and on learning great mathematics from primary sources, and has recently authored a fourth book, for students to learn number theory with an inquiry pedagogy from primary sources, primarily the manuscripts and letters of Sophie Germain, the first woman we know to have done important original mathematical research. David also created a graduate course on the role of history in teaching mathematics. He relies on student reading, writing, and mathematical preparation before class to enable active student work to replace lecture. He loves backpacking and wilderness, is active on environmental issues, and has become a fanatical badminton player.
