Abstract

Raymond Pearl spent the majority of his academic career (1918-1940) at Johns Hopkins University, where he was Professor of Biometry and Vital Statistics and Director of the Institute of Biological Research. Founder of the Quarterly Review of Biology and Human Biology, he made significant contributions in the areas of biology, genetics, eugenics, and statistics. The Pearl Papers includes correspondence as well as notebooks, scrapbooks, diplomas, photographs, and 33 volumes of diaries. There is significant correspondence with his wife, Maud (ca. 500 letters), and mother, Ida May (ca. 300 letters), particularly for the years 1895-1934. Of special note is Pearl's correspondence with his friend, colleague, and fellow Baltimoreian, H. L. Mencken (ca. 500 letters). The collection contains important information on the American Association of Physical Anthropologists, The Baltimore Sun, the Birth Control Federation of America, Dartmouth College, the International Institute of Statistics, Johns Hopkins University, and the National Academy of Sciences.

Background note

An early and influential advocate for the importation of statistics into biological analysis, Raymond Pearl was a pioneer in American population biology and ecology. The son of Frank Pearl, a grocery clerk and shoe factory foreman, and Ida May McDuffee, Pearl attended Dartmouth College (A.B., 1899) and the University of Michigan (Ph.D., 1902). Like many students of his generation, Pearl traveled abroad after receiving his doctorate to strengthen his education, studying first at the University of Leipzig in 1905, and then under Karl Pearson at University College London (1905-1906). It was Pearson who quickened Pearl's interests in quantitative analysis and fostered his first efforts to apply statistics to population genetics. He married Maud Mary Dewitt, a fellow student at Michigan, and long his collaborator, in 1903.

Pearl's first academic appointments upon returning to the States were as an instructor of zoology at the University of Pennsylvania (1906-1907) and as chair of the Department of Biology at the Maine Agricultural Experiment Station (1907-1918). Befitting his position in Maine, Pearl was engaged primarily in applied research in the genetics of poultry and cattle. Through studies aimed at increasing the productivity of egg-laying in chickens, he turned from an analysis of the inheritance of individual traits to patterns of inheritance in populations. Recognizing, as Mendelian theory predicted, that individuals often did not express the same traits as their parents, Pearl began to study population-level characteristics such as birth rate, death rate, and population size, and to reconceptualize the genetic and environmental dynamics of evolutionary change. His work took him variously into a reanalysis of Malthus' predictions on population density and into direct conflict with the tendencies of much eugenic research to focus on individual traits and individual couples. By 1915, his reputation had grown widely enough in scientific circles to merit election to the American Philosophical Society and, in 1916, to the National Academy of Sciences.

Leaving Maine to become Professor of Biometry at Johns Hopkins in 1918, Pearl entered into the most productive period of his career. At Hopkins, where he served variously as Professor of Biology (1923-1940) and as statistician at the Johns Hopkins Hospital (1919-1935), Pearl turned a statistical eye toward the dynamics of human populations, producing remarkably accurate and durable estimates of changes in world population based upon the best-guess estimates for birth rate and longevity. More controversially, based upon U.S. Census data from 1920, he and Lowell J. Reed theorized that the logistic (sigmoidal) curve was in effect a law of nature describing population growth: after a slow initial period of expansion, populations enter a phase of exponential growth until the they reach the carrying capacity of the environment and level off. Although recognized as a useful heuristic for exploring population dynamics, Pearl's aggressive promotion of the logistic curve and his truculence in its defence alienated many of his colleagues. In other research, Pearl experimented with the factors influencing population dynamics in Drosophila melanogaster, turned to estimates of life expectancy based upon occupation and personal habits, and entered into various statistical aspects of reproductive behavior. An inveterate opponent of most eugenic policies, and critic of eugenic research, he was nevertheless a strong and vocal supporter of birth control and population planning.

Using funds provided by the Rockefeller Foundation, Pearl established the Institute for Biological Research at Johns Hopkins in 1925, heading it throughout its five year existence. He was also active in numerous professional organizations, serving as president of the International Union for Scientific Investigation of Population Problems (1928-1931), the American Association of Physical Anthropologists (1934-1936), and the American Statistical Association (1939),and helping to found and edit the Quarterly Review of Biology in 1926 and Human Biology in 1929. An agile and prolific writer, Pearl wrote 17 books and nearly 700 articles during his career on a extraordinary range of subjects.

Scope and content

A major resource for study of American biometry in the first half of the 20th century, the Pearl Papers contain 14 linear feet of the professional correspondence of Raymond Pearl, longtime professor at Johns Hopkins University, 1.5 linear feet of correspondence with his mother, and one linear foot of letters from Pearl to his wife Maud, concentrated in the period before their marriage, 1897-1899. The Pearl Papers are a rich resource for study of the development of population genetics and population biology during the 1920s and 1930s, as well as biological statistics and biometry, and they contain valuable information on both eugenics and birth control.

African American History Note

Pearl's opposition to eugenics earned him both friends and adversaries (most notable among the latter, E. M. East), as reflected throughout the Pearl papers. His correspondence with East, Herbert Spencer Jennings, Karl Pearson, the National Association for the Advancement of Colored People, Ira Jewell Williams, Edwin B. Wilson, F. A. E. Crew, the Rockefeller Institute, and William T. Howard (among others) touches frequently on issues of genetics, eugenics, race, and human evolution. The correspondence with the N.A.A.C.P. comprises three folders of materials for the years 1927-1936, primarily concerning a study of Harlem Hospital.

Collection overview
1895-1940 Box 1-31

Reflecting Pearl's interests in the biometric study of human populations, the collection includes abundant correspondence relating to statistics, human evolution, demography, longevity, and birth control, but the topics covered in correspondence are very diverse. Among the most prolific correspondents were his antagonist, E. M. East (1879-1938), Leon J. Cole (b. 1877), Herbert Spencer Jennings (1868-1947), Alfred J. Lotka (1880-1949), Major Greenwood (b. 1880), T.H. Morgan, Margaret Sanger (1879-1966), Vilhjalmur Stefansson (1879-1962), William Henry Welch (1850-1934), E. B. Wilson, William Morton Wheeler (1865-1937), Corado Gini (b. 1881), Karl Pearson (1857-1936), Bernard Mallet (1859-1932), Robert Mearns Yerkes (1876-1956), and George Udny Yule (b.1871). The series of letters between Pearl and his friend H. L. Mencken (1880-1956), including several written at the time of the Scopes "monkey trial," are of particular interest.

Pearl's opposition to eugenics earned him both friends and adversaries (most notable among the latter, E.M. East), as reflected throughout the collection. His correspondence with East and Cole, Jennings, Pearson, the National Association for the Advancement of Colored People, I.J. Williams, E.B. Wilson, F.A.E. Crew, the Rockefeller Institute, and W.T. Howard (among others) touches frequently on issues of genetics, eugenics, race, and human evolution.

1895-1946 Box 31-35

Correspondence to his mother, Ida May, his wife, Maud, and a small number of letters to family and friends. Plus, letters to his daughter, Penelope Pearl. Includes postcards written to Raymond Pearl from scientists all over Europe.

1900-1941 Box 36-38

Primarily research notes, with some originals of printed works.

1902-1940 Box 39-56

Diaries, manuscripts, notebooks, scrapbooks, and scientific "commonplace books". The diaries consist of very brief daily entries with relatively little detail.

1897-1940 1.0 folder Box 57
Originals can be found in the oversize flat-file drawers.

Miscellaneous formal and informal photographs depicting Pearl and his associates throughout his career. In addition to a few portraits of Pearl there is an image of researchers at the Maine Biological Laboratory, 1897, and one taken at the dinner at the 10th Annual Meeting of the American Association of Physical Anthropologists held in honor of the 70th birthday of Ales Hrdlicka.
