Captain E. T. Barnette founded Fairbanks in August 1901 while headed to Tanacross (or Tanana Crossing, where the Valdez-Eagle trail crossed the Tanana River), where he intended to set up a trading post. The steamboat on which Barnette was a passenger, the Lavelle Young, ran aground while attempting to negotiate shallow water. Barnette, along with his party and supplies, were deposited along the banks of the Chena River 7 miles (11 km) upstream from its confluence with the Tanana River. The sight of smoke from the steamer's engines caught the attention of prospectors working in the hills to the north, most notably an Italian immigrant named Felice Pedroni (better known as Felix Pedro) and his partner Tom Gilmore. The two met Barnette where he disembarked and convinced him of the potential of the area. Barnette set up his trading post at the site, still intending to eventually make it to Tanacross.

Douglas Fairbanks, Sr. (May 23, 1883 – December 12, 1939) was an American actor, screenwriter, director and producer. He was best known for his swashbuckling roles in silent films such as The Thief of Bagdad, Robin Hood, and The Mark of Zorro.

An astute businessman, Fairbanks was a founding member of United Artists. Fairbanks was also a founding member of The Motion Picture Academy and hosted the first Oscars Ceremony in 1929. With his marriage to Mary Pickford in 1920, the couple became Hollywood royalty and Fairbanks was referred to as "The King of Hollywood", a nickname later passed on to actor Clark Gable. His career rapidly declined with the advent of the "talkies".

Fairbanks was born Douglas Elton Thomas Ullman (spelled "Ulman" by Douglas Fairbanks, Jr. in his memoirs) in Denver, Colorado, the son of H. Charles Ullman (born September 15, 1833) and Ella Adelaide Marsh (born 1847). He had a half-brother, John Fairbanks, Jr. (born 1873), and a full brother, Robert Payne Ullman (March 13, 1882 – February 22, 1948).
