Article abstract: Tendoy influenced his people to work peaceably with the white settlers of Wyoming.

When his father, Kontakayak, a Bannock war chief, died in combat with the Blackfoot, Tendoy (the Climber) became war chief of the Lemhi Bannock band. An ally of Washakie, to whom he was related on his mother's side, Tendoy believed in accommodating white settlement in the highlands of what would become Wyoming.

Unlike many Bannocks, who became destitute with the demise of their hunting economy, Tendoy and his band prospered by maintaining a trading relationship with white settlers, miners, and others. Even during the Nez Perce War, he maintained that his people would prosper by seeking accommodation. In February, 1875, President Ulysses S. Grant issued an order allowing the Lemhi Bannocks to remain on their ancestral lands. In 1892, however, they were removed to Fort Hall, Idaho. After Tendoy died there, local residents built a monument in his honor.
