Biographical / Historical:
Henry Wurtz (c. 1828-1910), chemist and editor, contributed to both the theory and practice of chemistry. He studied at the College of New Jersey (later Princeton), where his interest in scientific pursuits was awakened by studies under Joseph Henry and John Torrey. Between 1854 and 1856 he was state chemist and geologist of the New Jersey Geological Survey. In 1858 he was appointed professor of chemistry and pharmacy at the National Medical College of Washington, D.C. (later George Washington University). During this connection he served as chemical examiner in the United States Patent Office. In 1861 in New York he opened a private laboratory for general consulting work. During the years 1877-1887 he was engaged in developing processes for increasing the yields of paraffin oils and other by products of the distillation of coal. He devoted the remaining years of his life to his private consulting practice and took out numerous patents relating to the distillation of paraffin hydrocarbons and other chemical products.

Opened a private laboratory in New York for general consulting work, 1861. During 1877-1887 developed processes for increasing yields of paraffin oils and other by-products of coal distillation. Devoted remaining years of his life to private consulting practice and received numerous patents relating to the distillation of paraffin hydrocarbons and other chemical products.

Date:
undated
Scope and Contents:
Although the obvious intention of the organizers of this file was to produce a comprehensive, alphabetical file of images of important scientists, inventors, engineers, and other figures in the history of science and technology, the resulting representation of significant subjects is somewhat haphazard. Also, there are some portraits of subjects outside the intended fields, such as photographer Rudolf Eickemeyer, Jr., and figures from non technological business areas.

Several drawers of file cards accompany the photographs. Some duplicate the names and negative numbers of file images without providing additional information; some provide source data; and some represent images which are not in the file. Most of the National Portrait Gallery items are copied from a study collection of carte de visite and cabinet prints which is uncatalogued: special arrangements to view the originals must be made with that institution.
Arrangement:
Collection arranged into one series and arranged alphabetically by subjects' names.
Historical:
This "collection" is essentially an alphabetical browsing file of copy prints created by the Smithsonian Office of Printing and Photographic Services. The original images are photographs, lithographs, etchings, and other forms of portraits located in Smithsonian collections, especially those of curatorial divisions located in NATIONAL MUSEUM OF AMERICAN HISTORY, but there are also substantial numbers of images copies from illustrations in books and periodicals. The latter probably were created for use in Museum exhibits and publications over the years.

These prints apparently were gathered from various curatorial divisions and other sources by volunteers, probably under the direction of curator Deborah Warner, Division of Physical Sciences. The prints were dry mounted onto cardboard and identified with the subjects' names and the corresponding OPPS negative numbers in order to serve as a ready reference file.

This is entirely a file of second and third generation images, therefore, and differs in form from most Archives Center collections. The usual handling precautions for photographic imagery do not necessarily apply, and users are free to browse in the files without protective gloves.

Collection is open for research.

Articles
Technical notes
Date:
1944-1965
Scope and Contents:
The material includes technical notes, operating instructions and descriptions relating to projects which Hopper participated in at Harvard during and after World War II and later in the private sector. These projects involved the creation of the Navy's Mark I, II and III "mechanical calculators" (the fore runners of today's computers) and the UNIVAC and ENIAC civilian models. The photographs document both equipment and Hopper with her colleagues at work and on social occasions. There are numerous published articles and memoranda by Hopper and others on various technical aspects of computers. Clippings of newspaper and magazine articles relating to computers and their development are also included, as well as periodicals and brochures. A "humor file" contains jokes and anecdotes collected by Hopper.

Much of the material is annotated by Hopper, primarily through notations on 3 x 5 white slips of paper. Some of the annotations by Elizabeth Luebbert, who served as a summer research assistant in the Museum's Computer History Project.
Arrangement:
The collection is divided into eleven series.

Series 1: Technical Documents, 1944-1949

Series 2: Photographs of Mark II, 1948

Series 3: Photographs at Harvard, 1944-1945

Series 4: Reports and Articles, 1946-1948

Biographical / Historical:
Grace Murray Hopper (1906-1992) obtained her Ph.D. in mathematics from Yale University in 1934. She was an associate professor of mathematics at Vassar College when she joined the Women's Reserve of the United States Navy, Women Accepted for Volunteer Emergency Service (WAVES) in 1944 and was assigned to the computing project at Harvard University. She served under Commander Howard H. Aiken as a Wave until 1946, and remained at Harvard's Computation Laboratory as a research fellow until 1949. In that year she joined the Eckert-Mauchly Computer Corporation as a senior mathematician. When Eckert-Mauchly became a division of Remington Rand, Hopper remained as senior programmer, a title she retained until 1959. Subsequently, she served as systems engineer and director of automatic programming development (1959-1964) and staff scientist in systems programming (1964-1971) for the UNIVAC division of Sperry Rand Corporation. Hopper retired from UNIVAC in 1972, having returned to active service in the U.S. Navy from which she eventually retired with the rank of Rear Admiral.
