Barbour Lathrop, a wealthy world traveler, persuaded Fairchild to become a plant explorer for the
United States Department of Agriculture. Lathrop and another wealthy patron, Allison Armour, financed some of Fairchild's many explorations for new plants to be introduced into the U.S. Fairchild was the author of a number of popular books on his plant collecting expeditions. Of those early travels, Fairchild wrote, "I am glad that I saw a few of the quiet places of the world before the coming of automobiles...". For many years Fairchild managed the
Office of Seed and Plant Introduction of the U.S. Department of Agriculture in Washington, D.C. One accomplishment was to help introduce flowering cherry trees from Japan to Washington. He is also credited with introducing
kale,
quinoa and
avocados to Americans. In 1898, he established the
introduction garden for tropical plants in
Miami, Florida. In 1905 he married Marian Bell, the younger daughter of
Alexander Graham Bell. Fairchild was a member of the board of trustees of the
National Geographic Society, and an officer in what is now called the
Alexander Graham Bell Association for the Deaf and Hard of Hearing. In 1926, the Fairchilds built a home on an parcel on Biscayne Bay in
Coconut Grove, Florida. They named it "
The Kampong", after similar family compounds in
Java, Indonesia, where Fairchild had spent so many happy days collecting plants. He covered this property with an extraordinary collection of rare tropical trees and plants and eventually wrote a book about the place, entitled
The World Grows Round my Door. In 1984, The Kampong became part of the
National Tropical Botanical Garden. In 1938, he was honored by having the
Fairchild Tropical Botanic Garden in
Coral Gables named after him. He was also the namesake of David Fairchild Elementary in
South Miami.
University of Miami Fairchild was a member of the board of regents of the
University of Miami from 1929 to 1933. For three of those years he was chairman of the board. In 1933, he was awarded the
Public Welfare Medal from the
National Academy of Sciences. His son,
Alexander Graham Bell Fairchild, lived and worked as a research
entomologist for 33 years at the Gorgas Memorial Laboratory in
Panama. His daughter, Nancy Bell, married another entomologist,
Marston Bates, author of many books on
natural history. She herself wrote a book,
East of the Andes and West of Nowhere, about living in rural
Colombia during the 1940s. Fairchild is commemorated in the scientific name of a species of lizard,
Anolis fairchildi. Several plants were named after Fairchild, including
Indigofera heudelotii var.
