Samuel Pierpont Langley
Today, the mountain is named after Samuel Pierpont Langley. In the early 1870s, it was confused with Mount Whitney by early climbers, and called by this name. When the mistake was realized, the peak was alternately called Mount Corcoran, Cirque Peak, or Sheep Mountain; the former two names being later attached to other mountains. But its current name became established in local usage, and was made official by the Board on Geographic Names in 1943.
