Biography
editSwingle was born in Canaan, Pennsylvania,[1] and moved with his family to Kansas two years later.
He graduated from the Kansas State Agricultural College in 1890, and studied at the University of Bonn in 1895–96 and 1898. With William Ashbrook Kellerman he edited the exsiccata Kansas fungi (1889), a specimen series which is widely distributed in major herbaria.[2]
Swingle married Lucie Romstaedt in 1901; she died in 1910. He married Maude Kellerman, daughter of William Ashbrook Kellerman, in 1915 and they had four children. He died in Washington, D.C., on January 19, 1952.[1][3]
In 1927, botanist Elmer Drew Merrill published Swinglea, which is a genus of flowering plants from the Philippines, belonging to the family Rutaceae and named in Walter Tennyson Swingle's honor.[4]
Contribution to US agricultural industry
editSwingle worked at the United States Department of Agriculture (1891), investigated subtropic fruits, established laboratories in Florida, became an agricultural explorer, and (after 1902) had charge of crop physiology and breeding investigations. He developed the tangelo citrus hybrid in 1897 in Eustis, Florida.[5]
He made several visits to the Mediterranean countries of Europe, to North Africa, and to Asia Minor, from where he introduced the date palm, pistachio nut and other useful plants, as well as the fig wasp, to make possible the cultivation of Smyrna figs in California.
Swingle also traveled to Asia, bringing back 100,000 Chinese volumes on botany to the Library of Congress.[6]
Much of his research is published in the five-volume book, The Citrus Industry, of which he wrote a significant portion.
