A specialist in ciliate development and ecology, Gregory Antipa received a doctorate in Zoology at the University of Illinois in 1970, and since 1978, has been on faculty at San Francisco State University. Working with Paramecium, Conchophthirus, and other taxa, Antipa’s research has ventured into structure/function relationships, chemotaxis, and cellular adaptations, and he has been involved in research into the decomposition of organic wastes by protozoa. He is a member of several professional organizations, including the American Society for Cell Biology,the Microscopy Society of America, and the International Society of Protistologists.

The Antipa collection consists primarily of electron micrographs of ciliates Condylostoma, Trichodina, Conchophthirus, and the mussel encommensal Mytilophilus, along with a lab manual on protist culture and assorted notes.

Protist

Born in New York City in 1914, William Balamuth enjoyed a long career in protistology. Introduced to the field as a graduate student in Harold Kirby’s laboratory at the University of California Berkeley, Balamuth received his dissertation in 1939 for a study of regeneration in the heterotrichous marine ciliate, Licnophora macfarlandi. After several years at the University of Missouri and Northwestern, he returned to Berkeley in 1953 to replace his mentor. During the course of his career, Balamuth worked on fundamental issues in the biology of organisms ranging from parasitic amoebae to amoeboflagellates, publishing over 80 papers on culturing, nutritional requirements, cell cycling, and encystment. He died suddenly on June 10, 1981.

The Balamuth Collection consists of 114 drawings of ciliates prepared by William Balamuth for use in courses and publications between the 1930s and early 1960s, along with a handful of offprints of articles and scattered research notes.

The protistologist Lea Bleyman has conducted research into the genetics, mating systems, and life cycles of ciliates. A former student of Tracy Sonneborn, Bleyman has served as past Secretary and President (2001-2002) of the Society of Protozoologists, and spent many years on the faculty of the Department of Natural Sciences at Baruch College.

The Bleyman Papers contain lab and research notes, abstracts of talks and conference materials, along with some correspondence and annual progress reports from Baruch College. The earliest materials in the collection relate to her years as a student in Sonneborn’s lab.

Trichodina pediculus

The first professor of Natural History at the Massachusetts Agricultural College, Henry James Clark, had one of the briefest and most tragic tenures of any member of the faculty during the nineteenth century. Having studied under Asa Gray and Louis Agassiz at Harvard, Clark became an expert microscopist and student of the structure and development of flagellate protozoans and sponges. Barely a year after joining the faculty at Massachusetts Agricultural College at its first professor of Natural History, Clark died of tuberculosis on July 1, 1873.

A small remnant of a brief, but important career in the natural sciences, the Henry James Clark Papers consist largely of obituary notices and a fraction of his published works. The three manuscript items include two letters from Clark’s widow to his obituarist and fellow naturalist, Alpheus Hyatt (one including some minor personal memories), and a contract to build a house on Pleasant Street in Amherst.

Bronislaw Honigberg was a parasitologist who, though studying the intestinal parasites of amphibians, provided research for the U.S. Department of Public Health’s infections diseases lab. Born in Warsaw, Poland in 1920, Honigberg fled to the United States at the beginning of World War II, cutting short his Polish medical education to become an undergraduate at the University of California Berkeley, where he earned his B.A. (1943), M.A (1946) and Ph.D. (1960). Honigberg joined the University faculty in 1961 and taught in the zoology department until his death in 1992.

The collection is comprised of Honigberg’s lecture notes, including exams, lab exercises, and illustrative material. There is also five folder of reprints spanning the years 1949 to 1991 and thus representing Honigberg’s research throughout his career.

A pioneer in the chemistry of protists, Seymour H. Hunter (1911-2003) was among the founders of the Haskins Laboratories in 1935, helping to establish its programs in microbiology, genetics, and nutrition (now affiliated with Pace University). His diverse research interests centered on protist nutrition, and he is credited with significant advances in understanding the ecology of marine plankton and the development of culturing methods for algae and protists. Stemming from his work on nutrition in Euglena, he developed microbiological assays for the determination of vitamin B12 in human tissues, and other research was foundational for understanding of the role of chelation for metals in culture systems and clinical use. Sometimes called a “protozoology missionary,” Hutner was a founding member of the Society of Protozoologists And was noted for his ability to recruit and inspire students and colleagues.

The Hutner Papers contain a significant run of scientific correspondence concentrated in the 1970s and 1980s, relating to Hutner’s research, publications, and the Haskins Lab, along with a small amount of material relating to his position at Pace University and some personal correspondence.

John Kloetzel began his academic career in 1967 with his Johns Hopkins dissertation on the fine structure of the larval salivary gland in a dipteran. After a postdoctoral fellowship at the University of Colorado, however, he began publishing on the structure of the ciliate cytoskeleton, working on Euplotes for much of his nearly forty year career at the University of Maryland Baltimore County. A past president of the International Society of Protistologists, Kloetzel has retired to Oregon.

The bulk of the Kloetzel Papers consists of TEM and SEM micrographs of protists, along with some correspondence, grant proposals, and manuscripts.

A specialist in the cryptophycaea, Paul Kugrens was born in Latvia in 1942 and lived in Pegnitz, Germany, until he emigrated to the United States with his parents at the age of eight. After receiving bachelors and masters degrees in zoology at the University of Nebraska and a doctorate at Berkeley (1971), Kugrens joined the faculty at Colorado State, remaining there for thirty-seven years. His research centered on the cell biology and ultrastructure of the cryptophytes Chroomonas, Cryptomonas, and Rhodomonas, and microalgae such as Prymnesium and Cyanophora.

The Kugrens papers include extensive documentation of the research and professional activities of a phycologist, including correspondence, grants proposals, manuscripts, and field data, along with thousands of electronic micrographs.

Tracy M. Sonneborn

The experimental ciliatologist David L. Nanney spent much of his career studying the protozoan Tetrahymena. Under Tracy M. Sonneborn at Indiana University, he completed a dissertation in 1951 on the mating habits of Paramecium, but soon after joining the faculty at the University of Michigan, he turned his attention to Tetrahymena. During his subsequent career in Ann Arbor (1951-1959) and at the University of Illinois (1959-1991), Nanney made a series of fundamental contributions to the cytology, genetics, developmental biology, and evolution of ciliates, influencing the work of other biologists such as Joe Frankel, Janina Kaczanowska, Linda Hufnagel, and Nicola Ricci. Since his retirement in 1991, Nanney has remained in Urbana.

The Nanney Papers include a dense run of professional correspondence with ciliatologists, geneticists, students and colleagues regarding his pioneering research on ciliates and other professional matters. Of particular note is an extensive correspondence with Sonneborn, accompanied by several biographical essays written after Sonneborn’s death, and a large body of correspondence of the controversial reorganization of the biological sciences departments at the University of Illinois in the 1970s. The collection also includes a selection of Nanney’s writings and a handful of photographs.

The protistologist Hope T. Ritter (1919-2007) is recognized for his important research on the evolution of mitosis. A native of Allentown, Pa., Ritter received his doctorate at Lehigh University in 1955 for a study of the gut fauna in a subterranean termite. Building on this research during the 1950s, he became the first scientist to successfully culture Barbulanympha, a hindgut flagellate symbiont of the wood-eating cockroach Cryptocercus, which has since become a model organism for study of the evolution of mitosis. After teaching at Harvard (1957-1961) and SUNY Buffalo, Ritter moved to the University of Georgia in 1966, where he remained until his retirement from teaching in 1987.

The Ritter Papers contain valuable professional correspondence, lab notebooks, and a large number of electron micrographs documenting his research.
