Biography of David Knapp
David Goodwin Knapp was born in Indianapolis on July 20, 1907. He worked as a minor laboratory apprentice at the National Bureau of Standards from 1926 until 1928 and as laboratory technician at Indianapolis Power & Light Company from 1928 until 1936. He received his B.S. from Butler University in 1935. During 1936 and 1937 Knapp attended George Washington University. Also in 1936 Knapp began work as a geophysicist at the U.S. Coast & Geodetic Survey. David Knapp performed research in the areas of cartographic techniques in geomagnetism, solar-diurnal variations, arctic aspects of geomagnetism, induction effects in permanent magnets, equatorial and auroral electrojets as shown by magnetic events, dipole determinations, and the history of geomagnetism. Knapp was a member of the American Geophysics Union and the International Association of Geomagnetism and Aeronomy. He was the secretary of the Terrestrial Magnetism and Electricity section of the AGU from 1944 till 1950.
Scope and Contents of Collection
The collection focuses on terrestrial magnetism. The subjects covered are atmospheric electricity, aurora borealis, sunspots, storms, the ionosphere, compasses, and geomagnetic cartography. It contains scientific manuscripts, reports, drafts of papers, memoranda, correspondence, bibliographies, biographical references, photographs, illustrations, calculations, reprints and newspaper clippings. The correspondence deals mainly with the U.S. Coast and Geodetic Survey before and during Knapp’s time as a scientist there. The correspondence with R.S. Owendoff concerns Knapp’s critique and suggestions for Owendoff’s book. There are manuscripts, notes and newspaper clippings written and collected by Knapp dealing with aspects of terrestrial magnetism. There are manuscripts by other scientists and some government publications as well. There are theoretical discussions on handwritten and typed notes, and calculations dealing with a variety of topics in terrestrial magnetism. The bibliographical materials are comprised of subject bibliographies, a bibliography of Knapp’s works and a review of the literature dealing with terrestrial magnetism. The biographical materials are lists of biographical references and obituaries from 1952 till 1970. The pictorial materials are drawings of scientists and two photographs. The photographs are of the 1968 IAGA-WMS Symposium and the 1884 Polar Year Meeting. Correspondence accompanies the Polar Year Meeting photo. Before Knapp’s death, Joseph C. Cain culled this collection from Knapp’s files. As a result of the selection process, this collection appears to be thin in some areas. The general correspondence seems to be especially fragmented.

Arrangement of Collection
Organized into the following series: I. Correspondence; II. Manuscripts, Publications and Notes; III. Bibliographic and Biographical Materials; IV. Pictorial Materials.
The documents in this collection have been arranged chronologically by date, with the exception of materials with no date and the subseries entitled "Theoretical Discussions." The materials with no date were arranged alphabetically. The "Theoretical Discussions" were left in their original order, which appears to be roughly chronological.
Material Separated from Collection
Photographs and drawings were removed from the collection and placed in the Emilio Segrè Visual Archives. Photocopies of the photographs and drawings remain with the collection.
Provenance and Acquisition Information
The papers were donated by Joseph Cain in 1987.
Processing Information
This collection was processed by Heather McBride in January 2001.
Newspaper articles were photocopied onto acid-free paper and the originals were removed from the collection. All materials were rehoused in archival quality, acid-free folders and boxes. All notations made by the processor to assist with identification were made in pencil and enclosed in brackets. All other notations were previously on the documents in the collection when it was received.
