Ethel K. Allen (July 13, 1906 – May 7, 2006) was an American naturalist and soil microbiologist. For most of her professional career, she worked at the University of Wisconsin–Madison. One of her most notable contributions was the publication of The Leguminosae, a Source Book of Characteristics, Uses and Nodulation with her husband and fellow bacteriologist, Oscar N. Allen. This book has been described as the "de facto encyclopedia" about legumes and nitrogen fixation.[1]
