Orcutt (born 27 April 1864 in Hartland, Vermont; died in Haiti 25 August 1929) was a noted naturalist sometimes called "cactus man" because on many expeditions he found new species of cacti.

[1] He traveled there with Charles Christopher Parry, Cyrus Pringle, and Marcus E. Jones, with whom he learned to properly catalog, collect, and preserve specimens.

The year 1892 proved significant for him as his father died and he married a doctor from New York named Olive Lucy Eddy.

Eddy was among the first women to earn a Doctor of Medicine degree at the University of Michigan’s Homœopathic Medical College at Ann Arbor, in 1882.

[6] At first Orcutt primarily collected plant specimens, but his interest began to shift from botany to conchology (Eugene Coan identified Charles as a “pioneer malacologist”).

He shipped a huge collection of fossils he gathered in San Quintín Bay to the American Museum of Natural History in New York.
