Although the world-famous Elmo, Kansas fossil insect beds were discovered by E. H. Sellards at the turn of the twentieth-century, the first entomologist to systematically and critically study the insect fossils collected there was the renowned British scientist Dr. Robin John Tillyard (1881–1937). Tillyard spent his entire entomological career living in New Zealand and Australia, and most of his work on the Elmo fossils was done with specimens collected by the Yale Peabody Museum and shipped to him in New Zealand. But he also took a number of trips to London and Europe, travelling by steamship to the west coast of the United States, then across the country by rail, and by steamship again from the east coast of the U.S.A. to London, then back by the same route. He stopped in Kansas several times on these cross-country excursions, and was known to have visited the Elmo fossil locality on at least three occasions. Recently rediscovered photographs, taken by Kansas State University entomologist, Dr. Reginald H. Painter on field trips in 1928 and 1933, document Tillyard's visits to the fossil beds in the company of a number of Kansas entomologists.
