Margaret Armstrong was a prominent American designer and illustrator whose work in the botanical field began after 1910, when dust-jackets became a preferred book covering. In 1915, she and co-author J.J. Thornber published the first comprehensive field guide to wildflowers of the western US, specifically Washington, Oregon, California, Idaho, Nevada, Utah, and Arizona. Field Book of Western Wildflowers includes 500 monochrome illustrations and 48 color plates which Armstrong drew from careful observation in the field. She collected over 1000 specimens during this period, 188 of which are housed in the New York Botanical Garden Herbarium. Her watercolor botanical illustrations are on display at the Metropolitan Museum of Art. Armstrong's collection trips from 1911-1914 led her to become one of the first women to ascend the Victoria Glacier and walk the basin of the Grand Canyon, where she found species that were not previously described. In addition to her botanical contributions, she independently authored two biographies and three detective novels and illustrated over 300 book covers. |
