"In 1909, Peary mounted his eighth attempt to reach the North Pole, selecting Henson to be one of the team of six who would make the final run to the Pole. Before the goal was reached, Peary could no longer continue on foot and rode in a dog sled. Various accounts say he was ill, exhausted, or had frozen toes. In any case, he sent Henson on ahead as a scout. In a newspaper interview Henson said: “I was in the lead that had overshot the mark a couple of miles. We went back then and I could see that my footprints were the first at the spot.” Henson then proceeded to plant the American flag.
On November 28, 2000, the National Geographic Society awarded the Hubbard Medal to Matthew A. Henson posthumously. Dr. S. Allen Counter petitioned the National Geographic Society for many years to present its most prestigious medal to Henson. He attended the ceremony with Audrey Mebane, Henson’s 74-year-old great-niece. The medal was presented at the newly named Matthew A. Henson Earth Conservation Center (MAHECC) in Washington, D.C., and accompanied a scholarship given in Henson’s name by NGS.”
