About the Author: (from Mathematics Magazine, Vol.66 (1993)) Joan P. Hutchinson began seriously coloring maps in 1973, after receiving her Ph.D. from The University of Pennsylvania. She has taught primarily at Smith College and at Macalester College. Her many enjoyable sabbaticals at and visits to other colleges and universities, along with her interest in mountain climbing and backcountry skiing, have made her appreciate the importance of well-colored maps.
