species from South America, India and the Philippines, many of which he obtained from the collections of Holway. Arthur was a charter member of the Botanical Society of America (twice serving as President), the Mycological Society of America, American Phytopathological Society (where he also served as President), the American Association of University Professors, and many other learned societies. His first paper on the rust fungi was published in 1883 and he continued publishing on the subject for over half of a century, his final publication appearing in 1934. Arthur Herbarium During his tenure at Purdue, Arthur accumulated over 40,000 rust specimens. Although he housed them at Purdue, Arthur considered these specimens to be his property because he financed most out of his own pocket. When Purdue disagreed, Arthur hired moving vans and quietly packed up the entire herbarium, including cabinets, and moved it to his house. This caused a standoff with Winthrop E. Stone, President of Purdue, who directed that he return all of the specimens, papers, drawings and notes related to his work with the North American flora to the herbarium. Ultimately an agreement was reached between Arthur and the Trustees of Purdue University to reimburse Arthur for expenses he personally incurred to build and maintain the herbarium, paying him the grand sum of $1450 amounting to 3.5 cents per specimen. Today the Arthur Herbarium is located at Lilly Hall of Science at Purdue University and it still houses Arthur's priceless collections. The collection has grown to almost 100,000 specimens of rust fungi and is considered one of the most important holdings of these fungi in the world. It is currently directed by Dr. M. Catherine Aime. Personal life Arthur married Emily Stiles Potter of Lafayette, Indiana in 1901 and the two lived together until her death in 1935. His interests also extended into music. His premier piece was “Vive Purdue.” Arthur died in 1942 in Brook, Indiana. He is buried in Lafayette.
