There are correspondence (18.5 boxes), manuscripts (lectures and articles), research grant material, research data, and some personal notes from his graduate school days. He obtained his A.B., A.M., and Ph.D. (1929) from Columbia University, where he was the last graduate student to get his doctorate under T. H. Morgan (for a recollection of his days in Morgan's fly-room see, Schultz to G. W. Beadle, 7-31-70; he also worked with Morgan at the California Institute of Technology 1929-1936, 1941-1942). Schultz's career centered on the study of the nature and function of the gene; chemical genetics of Drosophila; cytochemical and nutritional techniques; cytochemistry of growth; and the pattern of human chromosomes.

As a Rockefeller Foundation fellow in 1937-1939 he worked under Torbjörn Caspersson at the Karolinska Institutet in Stockholm, Sweden (there are 11 folders of correspondence with Caspersson, 1937-1971). The remainder of his career was spent at the Institute for Cancer Research, Philadelphia, Pennsylvania, where he was Senior member and head of the Department of Genetics and Cytochemistry (1943-1957), and Chairman of the Division of Biology (1957-1969). Much of his tenure at the Institute was spent as an administrator, rather than on original research; he had much success in choosing, encouraging, and stimulating a brilliant research staff. He did not publish prolifically, relying more on lectures and informal discussions (there are 7 boxes of his lectures and articles). There is significant material relating to his participation in professional organizations: American Society of Naturalists (Pres., 1968); Genetics Society of America (Pres., 1963); National Research Council; and the National Science Foundation.

Since he was a poor correspondent, the collection consists of letters to him. Important correspondents include:

• Robert W. Briggs
• Torbjörn O. Caspersson
• Kenneth W. Cooper
• Cyril D. Darlington
• Milislav Demerec

Sedgwick, Adam (1785-1873)
British geologist, minister. APS 1860
Collection, 1825-1870. 0.25 lin. feet

Adam Sedgwick (1785-1873, APS 1860), geologist, was an important figure in the development of the modern discipline of geology. He was educated at Cambridge, being ordained in 1817. An excellent field geologist, he did significant work interpreting complex old rock in such places as Devonshire (naming the Devonian Period after that location), Cornwall, and the Lake District, correlating his findings with strata in places such as Germany. Sedgwick first interpreted strata from the period he named Cambrian. He served in many professional organizations and was honored for his work with the Wollaston and Copley medals. Sedgwick, a Liberal in politics, served on committees that reformed the administration of university education. Despite being a friend of Charles Darwin's, Sedgwick was critical of the materialist bent of Darwinian thought.

The 37 letters in the collection were acquired at various times, mainly through purchase, and assembled for the collection. The letters span the dates 1825-1870. Individually most letters are not especially significant, but collectively they touch on most aspects of Sedgwick's life and career. There are letters about Sedgwick's work on university reform, the Geological Museum at Cambridge, lectures, colleagues, travel, health, and family. Only one letter in the collection delves into detail about Sedgwick's geologic work.

Sepkoski, J. John (1948-1999)
Paleobiologist
Papers, 1969-1999. ca.65 linear feet

Trained as a stratigrapher and paleontologist at Harvard (Ph.D., 1977), Jack Sepkoski accepted his first academic appointment at the University of Rochester while he was still working on his degree. In 1978, he and David Raup were lured away to the University of Chicago, where they rapidly helped establish that school as the center of the new quantitative paleobiology. Sepkoski is best known for his quantitative analyses of the history and diversity of life and his efforts to define the shape of evolutionary expansion and extinction. His discovery of a statistically significant periodicity of mass extinction events was enormously influential, and helped facilitate acceptance of theories of the extraterrestrial origins of mass extinction. Sepkoski died of a heart attack at age 50 on May 1, 1999.

The Sepkoski Papers are a comprehensive collection of Sepkoski's professional correspondence and research notes.

Sessé y Lacasta, Martino de (1755-1809)

Catalogo de animales y plantas mexicanas, 1794. 1 vol. (223 pp.).

One of the great scientists of colonial Mexico, Martin de Sessé y Lacasta arrived in Mexico City from his native Aragon in 1780. A founder of the Botanical Garden in Mexico City, Sessé was also co-leader of the sixteen year long Royal Botanical Expedition, which surveyed the flora and fauna of the Spanish colonies from California to Costa Rica. Sessé returned to Spain in 1803 to write up the results of his expedition, but died before completing the project. The results were finally published in 1887, when they appeared as Plantae Novae Hispaniae and Flora Mexicana.

The Catalogo de animales y plantas Mexicanas by Martin de Sessé y Lacasta represents a catalog of plant and animal specimens collected by the Royal Botanical Expedition in Mexico as of 1794. The manuscript is arranged in three parts: a brief letter of introduction to the Conde Revillagigedo (11p.), an inventory of animal specimens (52p.), and an inventory of the plants (163p.). The plant and animal sections are organized by Linnaean class, with a code indicating whether they were drawn from life, whether a specimen was collected, and whether the species was new to science.
