friend and contemporary Augustus Fendler. The two also collaborated on horticultural experiments on cacti, and frequently corresponded on the matter of specimen collection. Among the animals he studied were tapeworms (Taenia), the opossum, squirrels and mudpuppies (Menobranchus). He was elected to the American Philosophical Society in 1862. Later explorations The death of his wife on January 29, 1879, greatly affected him. He turned to plants, seeking relief in study, but life and a continuance of its labors seemed to be almost hopeless. His condition changed but little during the remainder of the winter, but when in the spring C. S. Sargent came with the proposition that he should join him in a journey through the forests of the Pacific Coast region he accepted it. That journey, although a difficult one for a man of his age, was of great benefit to him physically. His shattered spirit also was much revived and, among his friends, he resumed and sustained his lifelong habit of cheerfulness of manner. Legacy He is commemorated in the names of several plants, including Engelmann Oak (Quercus engelmannii), Engelmann Spruce (Picea engelmannii), Apache Pine (Pinus engelmannii), Engelmann's quillwort or Appalachian quillwort (Isoetes engelmannii), and Engelmann's Prickly-pear (Opuntia engelmannii). Engelmann's botanical collection, valuable as containing the original specimens from which many western plants have been named and described, was given to the Missouri Botanical Garden. This gift led to the founding of the Henry Shaw School of Botany as a department of Washington University in St. Louis, where an Engelmann professorship of botany has been established by Shaw in his honor. Engelmann was interred in Bellefontaine Cemetery in St. Louis.
