Founded in Cap François, Saint Domingue (now Haiti) in August 1785, the Cercle des Philadelphes was one of the most prestigious colonial learned societies of the Ancien Regime. During its brief seven year existence, the Cercle pursued an agenda of promoting improvements in agriculture, manufactures, the arts and sciences, published five volumes of memoirs, and established correspondence with their peers in the American Philosophical Society and other learned societies. Their foreign membership included both Benjamin Franklin and Benjamin Rush. The Cercle des Philadelphes Collection is a small, but important assemblage of documents relating to French colonial science. Each of the documents is associated with Louis Narcisse Baudry de Lozières, the first president of the Cercle, including three certificates appointing him to office, and two important addresses. The first of these appears to be his opening remarks to the Cercle at its first public meeting on Aug. 15, 1784. The second is an early, but undated document outlining the organization of the Cercle and its aims.

The Scaliger Family Papers, when taken together, trace the history of a noble family that was originally from Italy but lived primarily in Agen, France from the mid-1500s through the mid-1800s. Beginning with the patriarch, Julius Caesar Scaliger (1484-1558), a celebrated Italian scholar and physician, the members of the Scaliger family upheld an illustrious reputation over the centuries as scholars, military leaders, and noblemen. Throughout their family's history, the Scaligers maintained that they were descended from the Della Scallas, Princes of Verona. It is as a result of the necessity to defend this claim as well as later attempts to prove their ties to their noble heritage that this collection of documents has remained so well intact. The Scaliger Family Papers is a collection that encompasses several different kinds of documents that span from 1539 to 1862 including letters, genealogical material, works by members of the Scaliger family, as well as military, legal, and financial documents.

This is a diverse collection, including correspondence, drafts of letters, notes and notebooks (on biometric methods; tables and formulae; science, nature and method; coefficient and correlation; vitalism; Japanese language); commonplace book (1924); autobiography; and over one hundred folders of unpublished writings. The correspondence and other material covers a variety of topics, including biology, eugenics, evolution and natural selection, human heredity, paramecia, protozoa genetics, U.S. immigration policy. There is much on the Seventh International Congress of Zoology (1907); letters to his father and wives, and from students and colleagues on his seventy-fifth birthday, 1943 (1 v.); diplomas and certificates of membership; and photographs.

The geneticist Milislav Demerec emigrated from Yugloslavia in 1919, spending nearly his entire career in the Department of Genetics at Cold Spring Harbor Laboratory. Working initially on the genetics of maize and later on Drosophila virilis, his research interests included radiation and chemical mutagenesis, and during the Second World War, penicillin and the genetics of antibiotic resistance. Demerec served as head of the laboratory at Cold Spring Harbor from 1941 until 1960. The Demerec collection contains the extant professional papers of Milislav Demerec, dating primarily from the time of his arrival at Cold Spring Harbor until his retirement. In addition to his correspondence with colleagues, the collection includes interesting material on the administration of Cold Spring Harbor laboratory during the 1940s and 1950s, data and research notes, material relating to professional organizations (e.g. Genetics Society of America, American Society of Naturalists), a lengthy series of lectures given by Demerec, and a large number of photographs pertaining to Demerec's research, but also to his colleagues and Cold Spring Harbor itself. There is also a Register of visitors to the laboratory (1927-1945) and a Milislav Demerec reprint list.
