John M. Martin earned his PhD in the philosophy of mathematics and, as an instructor at the University of Colorado, received a number of teaching awards for his innovative approaches to introductory calculus. His preoccupation with the mathematical infinite took a more practical turn with the establishment of Stonebridge Community Supported Agriculture Farm where he collaborates in the gardens and vineyards. First cousin thrice-removed to Hayes Perkins, Martin grew up reading the peripatetic traveler's diaries and remains fascinated with this complex adventurer whose intriguing world says so much about our own.
