    Biography/Administrative History

    Joseph Andorfer Ewan was born in Philadelphia in 1909. His family moved to the Los Angeles area in 1912. In 1928, he studied botany at the University of California Los Angeles and then transferred to Berkeley in 1933, where he received his Bachelor of Arts and worked as assistant to Willis Linn Jepson on A Flora of California. He married Ada Nesta Dunn in 1935. They left California in 1937 and moved to the University of Colorado Boulder, where Ewan worked as an instructor. During World War II, he served in the U.S. Foreign Economic Administration in South America, and worked briefly at the Smithsonian and U.S. Department of Agriculture. In 1947, Ewan was appointed Assistant Professor of Botany at Tulane University. He became Associate Professor in 1952, Professor in 1957, and Chair of Botany in 1972. He retired in 1977. Over the course of his career, Ewan published over 400 works, with a special focus on the history of botany in the United States. His systematic research interests included Delphinium, Gentianaceae, Macrocarpaea, and Vismia. Along with his wife Nesta, Ewan also compiled a large library on natural history, which was purchased by Missouri Botanical Garden in 1986. Ewan died in Mandeville, Louisiana in 1999.

    Scope and Content of Collection

    The collection consists of an unpublished manuscript and notes by Joseph Ewan titled Flora Gabrielensis, written around 1942 while Ewan was teaching botany at the University of Colorado Boulder. The manuscript is based on a series of collecting trips by Ewan to the San Gabriel Mountains from 1926 to 1937. The manuscript is divided into eight sections and two appendices, following Ewan’s original organization. Most sections contain a mixture of handwritten notes and typescripts. Also included are nearly sixty black-and-white transparencies, negatives, and photographs depicting plant specimens and magnifications of specimens by Ewan and others, and a small research file on Ewan and earlier collection inventories.
