The Harold W. Manter Laboratory of Parasitology is one of the the most important extant centers of Systematic Parasitology. The Harold W. Manter Laboratory of Parasitology was established 29 March 1971 at the University of Nebraska - Lincoln. In 1981 the HWML was designated one of three National Resource Centers for Parasitology and many students associated with the lab have been trained in systematics as well as other aspects of parasitology. Three Henry Baldwin Ward Medalists (the highest annual award that is given by the American Society of Parasitologists) were students in Parasitology and in the lab while Professor Mary Hanson Pritchard directed the laboratory (Professor Pritchard is now Curator Emeritus). In the past 5 years, more than 150 publications have resulted from research both in the HWML and from specimens loaned from, or deposited into, the HWML as types or vouchers. On an annual basis we process more than 50 loans outgoing per year and we receive thousands of specimens into the collection from researchers world-wide for archiving and safe storage of valuable voucher specimens. We have had more than 30 visiting scientists come to work in the HWML in the past 5 years, studying specimens and using the library.
