Cornelia Clarke was a pioneering early 20th-century nature and botanical photographer, celebrated for her striking images of plants, insects, and animals, published both nationally and internationally. She volunteered at the Grinnell College herbarium and left about 3,000 glass plate negatives to Henry Conard, a botany professor at Grinnell College. When Conard retired in the 1950's, he brought the negatives to the University of Iowa, where they remained until the botany department closed in the early 2000s. Thanks to a Grinnell College mini-grant, the Grinnell Historical Museum scanned about 100 of the negatives, preserving Clarke's remarkable work for future generations.
