Thayer Expedition
The Thayer Expedition was a scientific endeavor sponsored by Nathaniel Thayer Jr. which was an ecological and biological endeavor undertaken by multiple scientists, took place in 1865, and resulted in various type specimens that were later recognized as new species by those that had attended.[1]
This expedition, occurring from 1865 to 1866, took place at the end of the American Civil War, its maiden voyage from New York to Rio de Janeiro beginning in the war's final week.
