Timeline

1922

Esther Miriam Zimmer Lederberg (December 18, 1922 – November 11, 2006) was an American microbiologist and a pioneer of bacterial genetics.

She discovered the bacterial Virus λ and the bacterial fertility factor F, devised the first implementation of replica plating, and furthered the understanding of the transfer of genes between bacteria by specialized transduction.

Lederberg also founded and directed the now-defunct Plasmid Reference Center at Stanford University, where she maintained, named, and distributed plasmids of many types, including those coding for antibiotic resistance, heavy metal resistance, virulence, conjugation, colicins, transposons, and other unknown factors.

As a woman in a male-dominated field and the wife of Nobel laureate Joshua Lederberg, Esther Lederberg struggled for professional recognition.

Despite her foundational discoveries in the field of microbiology, she was never offered a tenured position at a university.

Textbooks often ignore her work and attribute her accomplishments to her husband.

Esther Miriam Zimmer was the first of two children born in the Bronx, New York, to a family of Orthodox Jewish background.

Her parents were David Zimmer, an immigrant from Romania who ran a print shop, and Pauline Geller Zimmer.

1923

Her brother, Benjamin Zimmer, followed in 1923.

Zimmer was a child of the Great Depression, and her lunch was often a piece of bread topped by the juice of a squeezed tomato.

Zimmer learned Hebrew and she used this proficiency to conduct Passover seders.

1938

Zimmer attended Evander Childs High School in the Bronx, graduating in 1938 at the age of 15.

She was awarded a scholarship to attend New York City's Hunter College starting that fall.

In college, Zimmer initially wanted to study French or literature, but she switched her field of study to biochemistry against the recommendation of her teachers, who felt that a woman would have more difficulty pursuing a career in the sciences.

She worked as a research assistant at the New York Botanical Garden, engaging in research on Neurospora crassa with the plant pathologist Bernard Ogilvie Dodge.

1942

She received a bachelor's degree in genetics, graduating cum laude in 1942, at the age of 19.

After her graduation from Hunter, Zimmer went to work as a research assistant to Alexander Hollaender at the Carnegie Institution of Washington (later Cold Spring Harbor Laboratory), where she continued to work with N. crassa and published her first work in genetics.

1944

In 1944 she won a fellowship to Stanford University, working as an assistant to George Wells Beadle and Edward Tatum.

When she asked Tatum to teach her genetics, he initially demurred until he made her determine why, in a bottle of Drosophila fruit flies, one fly had different colored eyes than the others.

This she worked out so successfully that Tatum made her his TA.

She later traveled west to California, and after a summer studying at Stanford University's Hopkins Marine Station under Cornelius Van Niel, she entered a master's program in genetics.

1946

Stanford awarded her a master's degree in 1946.

Her M.A. thesis was entitled "Mutant Strains of Neurospora Deficient in Para-Aminobenzoic Acid".

That same year, she married Joshua Lederberg, then a student of Tatum's at Yale University.

Lederberg moved to Yale's Osborn Botanical Laboratory and then to the University of Wisconsin after her husband became a professor there.

There she pursued a doctorate degree.

From 1946 to 1949, she was awarded a predoctoral fellowship by the National Cancer Institute.

Her thesis was "Genetic control of mutability in the bacterium Escherichia coli."

1950

She completed her doctorate under the supervision of R. A. Brink in 1950.

Lederberg remained at the University of Wisconsin for most of the 1950s.

It was there that she discovered lambda phage, did early research on the relationship between transduction and lambda phage lysogeny, discovered the E. coli F fertility factor with Luigi Luca Cavalli-Sforza (eventually publishing with Joshua Lederberg), devised the first successful implementation of replica plating with Joshua Lederberg, and helped discover and understand the genetic mechanisms of specialized transduction.

These contributions laid the foundation for much of the genetics work done in the latter half of the twentieth century.

Because of her work, she is considered to be a pioneer in bacterial genetics.

1951

She first reported the discovery in 1951 while she was a PhD student and later provided a detailed description in a 1953 paper in the journal Genetics.

She was working with an E. coli K12 strain that had been mutagenized with ultraviolet light.

When she incubated a mixture of the mutant strain with its parent E. coli K12 strain on an agar plate, she saw plaques, which were known to be caused by bacteriophages.

The source of the bacteriophage was the parental K12 strain.

The UV treatment had "cured" the bacteriophage from the mutant, making it sensitive to infection by the same bacteriophage that the parent produced.

1956

In 1956, Esther and Joshua Lederberg were honored for their fundamental studies of bacterial genetics by the Society of Illinois Bacteriologists, which awarded them the Pasteur Medal.

Esther Lederberg was the first to isolate λ bacteriophage.
