The Scientific Swindler (1884-1891)

A scientific swindler preyed on American scientists working in Geology during a period extending from 1884 to 1891, obtaining books, specimens, and money from a number of American scholars. He had a good knowledge of Eastern European languages, was well acquainted with the field and frequently assumed the names of prominent authorities. By the time he vanished from history, he had also accurately identified large numbers of specimens in American museum collections.
