The year was 1909—roughly three centuries after the Age of Discovery ended and five decades prior to the Space Race. For explorers of the period, the North Pole represented one of the last untrodden frontiers still up for grabs. Robert Peary ventured into the tundra in February of that year, hoping to beat his competitors to the spot. Upon returning to the U.S., Peary was celebrated as the first man to reach world’s northernmost point, but it was his assistant, an African-American man named Matthew Henson, who many experts now believe deserves the distinction.

Henson was born in Charles County, Maryland on August 8, 1866, a year after the end of the Civil War. His parents—both freeborn sharecroppers—died before they had a chance to see him grow up. Henson found himself orphaned at age 11 and under the care of relatives. With nothing tying him to his home in Washington D.C., at age 13 he set out on his own, trekking 40 miles to Baltimore mostly on foot.

He got his first taste of life on the open ocean as a cabin boy on the Baltimore-based vessel the Katie Hines. The work he did onboard consisted of humble tasks like peeling potatoes, but the ship’s skipper, Captain Childs, saw to it he received a first-class schooling in seamanship. At sea Henson was mentored in math, history, literature, and geography, and at port he was introduced to the cultures of places like Spain, France, North Africa, and China.

Following his voyages on the Katie Hines, Henson eventually returned to Washington D.C., where he accepted a job as a clerk at a hat shop. It was there that he crossed paths with the man who would shape his destiny. Robert Peary met Henson in 1887 as a U.S. Naval officer with fresh dreams of reaching the North Pole. When he entered the shop where Henson worked, looking to sell seal and walrus pelts from a recent expedition to Greenland, it immediately became clear the two were kindred spirits. Peary admired Henson’s experience and enthusiasm, so he hired him to join an upcoming surveying expedition to Nicaragua. Eager to see more of the world, the starry-eyed 21-year-old accepted.

On this trip Henson proved himself an invaluable aide. He used the skills he picked up at sea, like map-making, to help Peary and the crew navigate the Central American jungle over the next two years. At the end of their mission, Henson was among the first men Peary had in mind to accompany him on his next adventure.

After returning to the East Coast—specifically, Philadelphia—just long enough to start a new job as a Navy Yard messenger and marry his first wife, Eva Flint, Henson was preparing to set sail once again. This time the destination was the iced-over tip of Greenland. Robert Peary had grown obsessed with the idea of being the first person to reach the North Pole, and he wasn’t alone. Explorers from the U.S., Italy, and Norway were all clamoring to beat each other in the race to the top of the world.

The team’s initial trip to Greenland was the first of many expeditions into the unforgiving Arctic. With Henson at his side, Peary had a key advantage over his adversaries. Aside from serving as a blacksmith, carpenter, hunter, and dog trainer, Henson was one of the few Arctic explorers and the only member of Peary’s party who took the time to learn the Inuit language. He had a knack for building trust with the local people and quickly adapted to their ways of life. Robert Peary once said of his comrade: "He is a better dog driver and can handle a sledge better than any man living, except some of the best Esquimo [sic] hunters themselves."

It was this rapport with the Inuit and the habits borrowed from their lifestyle that helped Peary and Henson survive in the Arctic for so many years. During that time they seized tons of iron-rich meteorite (not without controversy), mapped Greenland’s ice cap in its entirety, and traveled deeper into the Arctic than any explorer had before them. Unfortunately, Henson’s success up north resulted in the failure of his marriage back home. He married his second wife, Lucy Ross, during a return visit in 1906, but his only son, Anauakaq, was born of an Inuit woman he met during his travels.

After 17 years spent intermittently in the Arctic, there was one goal Peary and Henson had yet to accomplish: setting foot on the North Pole. They launched what would be their eighth and final effort to reach the frozen finish line in the summer of 1908. With the icebreaking vessel the Roosevelt in their command, the crew reached Ellesmere Island at Canada’s northern edge in February 1909. It was the job of 20-odd men to station food and supplies along the route before returning to camp while a smaller group made the full trek to the Pole. That core team included Robert Peary, four Inuits named Ooqueah, Ootah, Egingwah, and Seegloo, and Matthew Henson. "Henson must go all the way," Peary reportedly said while planning the expedition. "I can’t make it there without him."

In the end, it fell on Henson to lead the party to their target. Peary was incapacitated with frostbitten feet for the final leg of the journey, and Henson filled in for him as he was towed along in a sled. The plan was to let Peary take over at the last minute so he could be the first man to stand at the spot that had occupied his dreams for decades. Unfortunately for him, the team overshot their journey. Not realizing their mistake until it was too late, Henson and two of the Inuit guides arrived at the Pole on April 6, 1909 with Peary still 45 minutes behind them.

When Peary finally caught up, Henson greeted him saying, "I think I'm the first man to sit on top of the world." This did not sit well with Peary. The two remained on strained terms for the duration of their trip. Henson later wrote: "From the time we knew we were at the Pole, Commander Peary scarcely spoke to me [...] It nearly broke my heart that he would rise in the morning and slip away on the homeward trail without rapping on the ice for me, as was the established custom." By the time the two of them made it back home, one of the most successful partnerships in the history of exploration had disintegrated.

The controversy over who deserved of title of first person to reach the North Pole wasn’t limited to the two men. After returning to the States, they learned that another American, Frederick Cook, claimed to have beat them to the pole a year earlier. The photographic evidence Cook used to back up his assertion was eventually discredited, and in 1911 a Congressional Inquiry led to the official recognition of Peary’s achievement. (Today, Peary's claim to have reached the North Pole is still disputed.)

Robert Peary’s legacy would be cemented in history books from that point forward, but due to his skin color, Matthew Henson’s contributions were largely written out of the story. For a time, he struggled to find enough work to support his family. But though he may not have received all the credit he deserved during his lifetime, his feats didn’t go unrecognized. In 1937, he was made an honorary member of the prestigious Explorers Club in New York City. In 1944, he was awarded a Congressional medal, and he was honored by Presidents Truman and Eisenhower during the 1950s. Henson spent the last chapters of his life working at the U.S. Customs Bureau in New York City.

Matthew Henson died on March 9, 1955 at 88 years old. His remains were initially buried in Woodlawn Cemetery in the Bronx, but he's since been laid to rest alongside Robert Peary in Arlington National Cemetery.
