Joshua Lederberg Pioneer of microbial genetics: Joshua Lederberg (1925-) by King-Thom Chung, Department of Biology, The University of Memphis Joshua Lederberg was awarded the 1958 Nobel Prize in medicine and physiology for his discovery of "sexual recombination" in bacteria (bacterial conjugation). This award was shared with Drs. George Wells Beadle (1903-1989) (1) and Edward Lawrie Tatum (1909-1975) (3). Conjugation is mediated by the presence of the F+ factor (fertility factor or plasmid) and requires cell to cell contact. The plasmid can reside inside the donor bacterium as an extrachromosomal element with its own origin of replication or it can be integrated into the bacterial chromosome. When integrated in the chromosome, replicative transfer begins within the F plasmid region at the oriT region and continues into the chromosomal region. Thus the chromosomal genes as well as F plasmid genes are transferred to the recipient cell during conjugation. Via a process of recombination ( Hfr and coined the term plasmid in 1950 to describe extrachromosomal genetic elements. However, the term was not widely accepted until the 1970s when bacterial drug resistance was shown to be mediated by self-transmissible plasmids and became a major medical problem.

Hearing on the Collections of Information Antipiracy Act Statement of Joshua Lederberg President-emeritus Rockefeller University on behalf of the National Academy of Sciences National Academy of Engineering Institute of Medicine and American Association for the Advancement of Science before the Committee on the Judiciary U.S. House of Representatives 18 March 1999 Testimony Joshua Lederberg President-emeritus Rockefeller University 18 March 1999 Introduction My name is Joshua Lederberg. I have been asked to testify on behalf of the U.S. National Academy of Sciences, National Academy of Engineering, Institute of Medicine (the "Academies"), and the American Association for the Advancement of Science (AAAS). As you know, the three Academies were chartered by Congress to provide advice to the federal government and to the nation on scientific, technical, and medical issues. The AAAS is the umbrella organization for over 250 professional scientific and engineering societies in the United States, with more than 140,000 individual members. I was elected as member of the National Academy of Sciences in 1957 and am a charter member of the Institute of Medicine. I also am Fellow of the AAAS. My biographical summary is attached at the end of this statement. I would like to make several points in this testimony: Access to factual data is essential to furthering our understanding of nature, to medical and technical progress, and to the validation of scientific claims. The essence of the scientific method is relentless critical discourse; without it, the authenticity of knowledge claims rapidly deteriorates. Indeed, a thriving public domain for data, fostered by government policies that guarantee full and open access to data, benefits all downstream users, including the commercial database industry.

Where were your parents born? Prof. Joshua Lederberg - In Israel. They came to the US in 1924. LP - Did they settle down and find jobs here right away? JL - Well, I don't really know the details. My father was an orthodox rabbi, and I think he had a very temporary position in Montclair after I was born, and then six months later he got a more permanent position in a synagogue in Washington Heights, which is when we moved to New York City LP - Did your parents have a large formative influence on you? JL - Certainly so. My father was quite an idealistic person. He was committed to a religious vocation, and I reacted quite strongly to that: I was as early as I could remember interested in scientific and secular affairs. We still shared a great deal. He eventually gave in, and said "Joshua, I guess there are many ways to follow the Torah , and if you want to seek truth through science, that's alright too."

chronology of his life Joshua Lederberg (b. 1925) is exceptional even among the select and illustrious group of Nobel prize recipients. More than most of his peers, he has combined pioneering researchin genetics, molecular biology, and computer sciencewith concern for public issues, especially health care policy, environmental protection, science education, and arms control. This Exhibit highlights how one outstanding scientist has bridged the divide between science, society, and politics during the second half of the twentieth century Unless noted otherwise, items in this exhibit are drawn from the Joshua Lederberg papers,donated by Dr. Lederberg to the National Library of Medicine in 1998. The Library is publishing a comprehensive selection of the Lederberg papers on its Profiles in Science Joshua Lederberg using a microtome at the American Institute, 1941. While a high school student in Manhattan, Lederberg participated in the American Institute, a research facility for gifted youths in the sciences that had grown out of the 1939 New York World Fair. The Institute provided Lederberg with laboratory space and equipment such as a microtome, a device used for cutting thin slices of tissue for microscopical examination.

Lederberg, Joshua Joshua Lederberg, 1958 Hulton Deutsch Collection/Corbis (b. May 23, 1925, Montclair, N.J., U.S.) , American geneticist, pioneer in the field of bacterial genetics, who shared the 1958 Nobel Prize for Physiology or Medicine (with George W. Beadle and Edward L. Tatum ) for discovering the mechanisms of genetic recombination in bacteria. Lederberg studied under Tatum at Yale (Ph.D., 1948) and taught at the University of Wisconsin (1947-59), where he established a department of medical genetics. In 1959 he joined the faculty of the Stanford Medical School, serving as director of the Kennedy Laboratories of Molecular Medicine there from 1962 to 1978, when he moved to New York City to become president of Rockefeller University. He held that post until 1990. With Tatum he published "Gene Recombination in Escherichia coli " (1946), in which he reported that the mixing of two different strains of a bacterium resulted in genetic recombination between them and thus to a new, crossbred strain of the bacterium. Scientists had previously thought that bacteria only reproduced asexually i.e.

He showed that bacteria can reproduce sexually, combining genetic material so that offspring possess characteristics of both parent organisms. He shared the prize with George Beadle and Edward Tatum. Lederberg is a pioneer of genetic engineering, a science that relies on the possibility of artificially shuffling genes from cell to cell. He realized in 1952 that bacteriophages, viruses which invade bacteria, can transfer genes from one bacterium to another, a discovery that led to the deliberate insertion by scientists of foreign genes into bacterial cells.
