Logan Fontenelle, an interpreter and Omaha chief, was born at Bellevue in May 1825. His father was Lucien Fontenelle, a noted fur trader both on the lower Missouri River and near Fort Laramie. His mother was a daughter of Big Elk, noted chief of the Omaha. Logan, the eldest of four sons and one daughter, was educated at a private school near St. Louis before joining th family at Fort Laramie in 1837. Two years later the family returned to Bellevue where the father died.

Little is known of Logan's life for the next decade, but in the early 1850s he became recognized as a chief of the Omaha by both the tribe and the U.S. government. As both chief and interpreter, he went with the Omaha chiefs to Washington, D.C. where they signed a treaty on March 10, 1864, selling most of their land to the government and restricting themselves to a reservation in northeast Nebraska. This opened the Nebraska Territory for settlement.

... Logan Fontenelle accompanied a party of Omaha on a buffalo hunt near here in present Boone County. This party was attacked by Sioux and Logan was killed, probably on July 17th. His body was returned to Bellevue where he was buried.
