Born in Charles County, Md., in 1866, Henson went to sea at age 13 and for several years traveled all around the world. When he first met Peary, Henson was in his early 20s, and their shared sense of adventure bound them together for more than 20 years. Henson accompanied Peary on several attempts to reach the North Pole, which they finally reached together April 6, 1909.
