Shirley Gale Cross (August 27, 1915, Oklahoma – July 14, 2008, East Sandwich, Massachusetts) was an American botanist, botanical illustrator, and conservationist.[1]
Shirley Gale grew up in Gloucester and Marblehead and graduated from Massachusetts State College (renamed in 1947 the University of Massachusetts Amherst). At Radcliffe College, she received her Ph.D. in 1939[2] with M. L. Fernald as her thesis supervisor.[1]
In 1941, she married Chester "Chet" E. Cross (1913–1988), her classmate who received a Ph.D. in paleobotany from Harvard. The couple moved to the Spring Hill Historic District of Sandwich, Massachusetts, where they owned and cultivated three cranberry bogs to supply cranberries for the fresh fruit market. They continued growing cranberries until shortly before Chet Cross's death.[1] She and Gordon Dillon drew the illustrations for Edith Scamman's[3] 1947 book Ferns and Fern Allies of New Hampshire.[4] Shirley Gale Cross drew the Rhynchospora illustrations[1] and many of the fern illustrations for the 8th edition of Gray's Manual of Botany.[5]
Cross was a founding member of the Thornton W. Burgess Society and conceived, designed, cultivated, and organized the Society's wildflower garden named in her honor.[6]
Upon her death, she was survived by three sons, six grandchildren, and one great-grandchild.[7]
