Waldo Rudolph Tobler was an American-Swiss geographer and cartographer. Tobler is regarded as one of the most influential geographers and cartographers of the late 20th century and early 21st century.

Cindi Katz, a geographer, is Professor in Environmental Psychology, Earth and Environmental Sciences, American Studies, and Women's Studies at the CUNY Graduate Center.
