About the author

Born in Hadley, Massachusetts, on December 20, 1855, Charles Dwight Marsh was an American botanist and biologist whose work connected careful observation with real-world problems. He studied at Amherst College and later earned a Ph.D. from the University of Chicago.

Marsh became especially known for his work with the U.S. Department of Agriculture, where he led field experiments on locoweed and other toxic plants that affected livestock. He also studied plankton, with a focus on copepods, and served as an honorary curator of that group at the U.S. National Museum.

His research took him beyond the laboratory. In the 1910s he worked on the Smithsonian Biological Survey of the Panama Canal Zone, and surviving field notebooks show the detail and range of his scientific interests. He died on April 23, 1932.
