Cartographer Solved the 'Greenland Problem'
Arthur Robinson, who died Oct. 10 at the age of 89, is best known for the "Robinson projection." It was a solution to the "Greenland problem," an age-old cartographers' bugaboo wherein Greenland looks disproportionately large on maps drawn to the most familiar Mercator projection. NPR's Melissa Block talks with Joel Morrison, one of Robinson's former students.
