This accession consists of records created and maintained by Ray Kondratas, Curator, Division of Medical Sciences, in his work researching and conducting interviews
for the Smithsonian Videohistory Program. The videohistories produced by Kondratas covered such topics as DNA sequencing; Acuson ultrasound machines; fluorescence activated
cell sorting instrumentation; the polymerase chain reaction (PCR) technique; diagnostic imaging technology; and the project to sequence the smallpox virus genome. Also included
is an interview with Vsevold Kuravcev, regarding his work in nuclear magnetic resonance. Materials include correspondence; memoranda; reports; research notes; biography files;
proposals; transcripts; audio and video recordings; images; brochures; posters; and clippings. Some materials are in electronic format.
The Smithsonian Videohistory Program, funded by the Alfred P. Sloan Foundation from 1986 until 1992, used video in historical research. Additional collections have
been added since the grant project ended. Videohistory uses the video camera as a historical research tool to record moving visual information. Video works best in historical
research when recording people at work in environments, explaining artifacts, demonstrating process, or in group discussion. The experimental program recorded projects that
reflected the Institution's concern with the conduct of contemporary science and technology.
Smithsonian historians participated in the program to document visual aspects of their on-going historical research. Projects covered topics in the physical and biological
sciences as well as in technological design and manufacture. To capture site, process, and interaction most effectively, projects were taped in offices, factories, quarries,
laboratories, observatories, and museums. Resulting footage was duplicated, transcribed, and deposited in the Smithsonian Institution Archives for scholarship, education,
and exhibition. The collection is open to qualified researchers.
Ramunas Kondratas, curator at the Smithsonian's National Museum of American History (NMAH), was interested in documenting the history, development, and applications
of the DNA Sequencer. He also explored the commercialization of the instrument, including its testing and marketing, and addressed current and future uses of the ABI 370A
model sequencer in medical research. Sessions were recorded at California Institute of Technology in Pasadena, California, on October 19, 1988, at Applied Biosystems, Inc.,
in Foster City, California, on October 21, 1988, and at the National Institutes of Health (NIH) in Washington, D.C., on March 27, 1990.
Interviewees included scientists and technicians at Cal Tech, ABI, and NIH. Jeannine Gocayne received a M.A. in molecular biology from the State University of New York-Buffalo
in 1985 and was appointed a biologist and sequencing supervisor with the Receptor Biochemistry and Molecular Biology Section of the Laboratory of Molecular and Cellular Neurobiology,
National Institute of Neurological Disorders and Stroke (NINDS), NIH in 1986.
Several others provided additional information about the sequencer for the three video sessions. These people included: Kurt Becker, DNA Sequencing Product Manager; Kip
Connell, research scientist; Marilee Shaffer, products specialist for DNA sequencing, ABI; and Anthony R. Kerlavage and W. Richard McCombie of the Receptor Biochemistry and
Molecular Biology Section of the Laboratory of Molecular and Cellular Neurobiology, NINDS, NIH.
Session one took place at the California Institute of Technology with Hood, Sanders, and Kaiser. Interviews focused on the history, design, and development of the sequencer
prototype and its operation.
Session Two took place at Applied Biosystems, Inc., with Hunkapiller, Becker, Connell, and Shaffer and dealt with the commercial design, fabrication, and marketing of the
sequencer and other related instrumentation. Tours of the assembly and manufacturing areas were included in the session, as well as a demonstration of how the DNA sequencing
data is represented graphically on a computer.
Session Three took place at the Receptor Biochemistry and Molecular Biology Section of the Laboratory of Molecular and Cellular Neurobiology, NINDS, NIH, where Venter explained
and demonstrated the automated DNA sequencing processes during a tour of the lab. Kerlavage and McCombie assisted during the tour. Finally, Gocayne described the application
of new DNA sequencing technology to work in the lab.
This collection consists of three interview sessions, totaling approximately 8:40 hours of recordings, and 176 pages of transcript. There are three generations of tape
for each session: originals, dubbing masters, and reference copies. In total, this collection is comprised of 26 original videotapes (26 Beta videotapes), 22 dubbing master
videotapes (22 U-matic videotapes), and 5 reference copy videotapes (5 VHS videotapes). The collection has been remastered digitally, with 26 motion jpeg 2000 and 26 mpeg
digital files for preservation, and 22 Windows Media Video and 22 Real Media Video digital files for reference.
Restrictions: Ramunas Kondratas must approve before broadcast or public viewing.
DNA is composed of the four individual nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). To decipher a particular piece of DNA, it is necessary
to determine the exact sequence of these nucleotides. The sequence of the nucleotides determines the genetic information encoded in a DNA strand. A partial nucleotide sequence
for a human gene might look like: GGCACTGACTCTCTC. In 1977, biochemist Fred Sanger developed the enzymatic chain termination procedure that allowed for sequencing of individual
strands of DNA. This made mapping and sequencing of genetic material possible.
In 1986, Leroy E. Hood's Laboratory at the California Institute of Technology (Cal Tech) announced its development of a semiautomated machine for sequencing DNA. The machine
automated the enzymatic chain termination procedure for DNA sequence analysis developed by Sanger and became a key instrument in mapping and sequencing genetic material. That
same year, Applied Biosystems, Inc. (ABI) produced the first commercial instruments for clinical use. Constant improvements in the technology resulted in faster sequencing
capacity, which was significant for advanced scientific research in projects such as mapping the human genome.
Leroy E. Hood received his M.D. from The Johns Hopkins School of Medicine in 1964, and a Ph.D. in immunology from Cal Tech in 1968. From 1968 until 1970 he held a postdoctoral
fellowship at the National Institutes of Health. In 1970 he was appointed professor of biology at Cal Tech and eventually became chairman of the Division of Biology and the
director of its cancer center.
Michael Hunkapiller received a Ph.D. in chemistry from Cal Tech in 1974. He joined ABI as its vice president for research and development in 1983.
Robert J. Kaiser received his Ph.D in chemistry from Cal Tech in 1983, and subsequently joined the Cal Tech staff as a research fellow in biology. Jane Z. Sanders joined
the Cal Tech staff in 1984 as an associate biologist and was appointed senior biologist a year later. She took graduate courses in biochemistry in 1971-72 at the Stanford
University Medical School.
Lloyd M. Smith received a Ph.D. in biophysics from Stanford University in 1981, and was a senior research fellow in biology at Cal Tech from 1982 until 1987, when he was
appointed assistant professor in the Analytical Division of the Department of Chemistry at the University of Wisconsin-Madison.
J. Craig Venter received his Ph.D. in physiology and pharmacology from the University of California, San Diego in 1975. In 1983 he was appointed adjunct professor of biochemical
pharmacology at the State University of New York-Buffalo and joined NIH in 1984 as chief of the Receptor Biochemistry and Molecular Biology Section, NINDS. In 1987 he also
became co-director of the Laboratory of Molecular and Cellular Neurobiology, NINDS, NIH and was appointed director of the NINDS DNA facility at NIH.
