James Edward Grant July 2, — February 19, was an American short story writer and screenwriter who contributed to more than fifty films between and He collaborated with John Wayne on twelve projects, starting with Angel and the Badman which he also directed in through Circus World in Support Your Local Gunfighter was released in , five years after his death.

Later, she made an extensive study of the cytogenetics and ethnobotany of maize races from South America. McClintock's research became well understood in the s and s, as other scientists confirmed the mechanisms of genetic change and protein expression that she had demonstrated in her maize research in the s and s.

Awards and recognition for her contributions to the field followed, including the Nobel Prize in Physiology or Medicine, awarded to her in for the discovery of genetic transposition ; she was the only woman to receive an unshared Nobel Prize in that category.

The youngest, Malcolm Rider called Tom , was born 18 months after Barbara. When she was a young girl, her parents determined that Eleanor , a "feminine" and "delicate" name, was not appropriate for her, and chose Barbara instead.

From the age of three until she began school, McClintock lived with an aunt and uncle in Brooklyn, New York in order to reduce the financial burden on her parents while her father established his medical practice.

She was described as a solitary and independent child. She was close to her father, but had a difficult relationship with her mother, tension that began when she was young.

The McClintock family moved to Brooklyn in and McClintock completed her secondary education there at Erasmus Hall High School ; [6] [7] she graduated early in Her mother resisted sending McClintock to college, for fear that she would be unmarriageable, something that was common at the time.

McClintock began her studies at Cornell's College of Agriculture in There, she participated in student government and was invited to join a sorority , though she soon realized that she preferred not to join formal organizations.

Instead, McClintock took up music, specifically jazz. She studied botany , receiving a B. Sc in The course was based on a similar one offered at Harvard University, and was taught by C.

Hutchison , a plant breeder and geneticist. McClintock pointed to Hutchison's invitation as a catalyst for her interest in genetics: "Obviously, this telephone call cast the die for my future.

I remained with genetics thereafter. During her graduate studies and postgraduate appointment as a botany instructor, McClintock was instrumental in assembling a group that studied the new field of cytogenetics in maize.

This group brought together plant breeders and cytologists, and included Marcus Rhoades , future Nobel laureate George Beadle , and Harriet Creighton.

Emerson , head of the Plant Breeding Department, supported these efforts, although he was not a cytologist himself.

Sharp , both Cornell botanists. McClintock's cytogenetic research focused on developing ways to visualize and characterize maize chromosomes.

This particular part of her work influenced a generation of students, as it was included in most textbooks. She also developed a technique using carmine staining to visualize maize chromosomes, and showed for the first time the morphology of the 10 maize chromosomes.

This discovery was made because she observed cells from the microspore as opposed to the root tip. In , McClintock was the first person to describe the cross-shaped interaction of homologous chromosomes during meiosis.

The following year, McClintock and Creighton proved the link between chromosomal crossover during meiosis and the recombination of genetic traits.

McClintock's breakthrough publications, and support from her colleagues, led to her being awarded several postdoctoral fellowships from the National Research Council.

This funding allowed her to continue to study genetics at Cornell, the University of Missouri , and the California Institute of Technology , where she worked with E.

Exposure to X-rays can increase the rate of mutation above the natural background level, making it a powerful research tool for genetics.

Through her work with X-ray-mutagenized maize, she identified ring chromosomes , which form when the ends of a single chromosome fuse together after radiation damage.

She showed that the loss of ring-chromosomes at meiosis caused variegation in maize foliage in generations subsequent to irradiation resulting from chromosomal deletion.

McClintock received a fellowship from the Guggenheim Foundation that made possible six months of training in Germany during and Instead, she worked with geneticist Richard B.

During her time at Missouri, McClintock expanded her research on the effect of X-rays on maize cytogenetics. McClintock observed the breakage and fusion of chromosomes in irradiated maize cells.

She was also able to show that, in some plants, spontaneous chromosome breakage occurred in the cells of the endosperm.

Over the course of mitosis , she observed that the ends of broken chromatids were rejoined after the chromosome replication.

The broken ends were rejoined in the interphase of the next mitosis, and the cycle was repeated, causing massive mutation, which she could detect as variegation in the endosperm.

For this reason, it remains an area of interest in cancer research today. Although her research was progressing at Missouri, McClintock was not satisfied with her position at the University.

She recalled being excluded from faculty meetings, and was not made aware of positions available at other institutions. As far as I can make out, there is nothing more for me here.

The university's retaliation against Stadler amplified her sentiments. In early , she took a leave of absence from Missouri in hopes of finding a position elsewhere.

She accepted a visiting Professorship at Columbia University , where her former Cornell colleague Marcus Rhoades was a professor. In December , she was offered a research position by Milislav Demerec , the newly appointed acting director of the Carnegie Institution of Washington 's Department of Genetics Cold Spring Harbor Laboratory ; McClintock accepted his invitation despite her qualms and became a permanent member of the faculty.

After her year-long temporary appointment, McClintock accepted a full-time research position at Cold Spring Harbor Laboratory. There, she was highly productive and continued her work with the breakage-fusion-bridge cycle, using it to substitute for X-rays as a tool for mapping new genes.

In , in recognition of her prominence in the field of genetics during this period, McClintock was elected to the National Academy of Sciences —only the third woman to be elected.

The following year she became the first female president of the Genetics Society of America ; [3] she had been elected its vice-president in He invited her to Stanford to undertake the study.

She successfully described the number of chromosomes, or karyotype , of N. Beadle said, "Barbara, in two months at Stanford, did more to clean up the cytology of Neurospora than all other cytological geneticists had done in all previous time on all forms of mold.

In the summer of at Cold Spring Harbor Laboratory , McClintock began systematic studies on the mechanisms of the mosaic color patterns of maize seed and the unstable inheritance of this mosaicism.

She found that the Dissociation did not just dissociate or cause the chromosome to break, it also had a variety of effects on neighboring genes when the Activator was also present, which included making certain stable mutations unstable.

In early , she made the surprising discovery that both Dissociation and Activator could transpose, or change position, on the chromosome.

She observed the effects of the transposition of Ac and Ds by the changing patterns of coloration in maize kernels over generations of controlled crosses, and described the relationship between the two loci through intricate microscopic analysis.

The size of the colored spot on the seed is determined by stage of the seed development during dissociation. McClintock also found that the transposition of Ds is determined by the number of Ac copies in the cell.

Between and , she developed a theory by which these mobile elements regulated the genes by inhibiting or modulating their action. She referred to Dissociation and Activator as "controlling units"—later, as "controlling elements"—to distinguish them from genes.

She hypothesized that gene regulation could explain how complex multicellular organisms made of cells with identical genomes have cells of different function.

In summer , she reported her work on the origin and behavior of mutable loci in maize at the annual symposium at Cold Spring Harbor Laboratory, presenting a paper of the same name.

The paper delved into the instability caused by Ds and Ac or just Ac in four genes, along with the tendency of those genes to unpredictably revert to the wild phenotype.

She also identified "families" of transposons, which did not interact with one another. Her work on controlling elements and gene regulation was conceptually difficult and was not immediately understood or accepted by her contemporaries; she described the reception of her research as "puzzlement, even hostility".

She published a paper in Genetics in , where she presented all her statistical data, and undertook lecture tours to universities throughout the s to speak about her work.

She was interested in studying the evolution of maize through chromosomal changes, [57] and being in South America would allow her to work on a larger scale.

McClintock explored the chromosomal, morphological, and evolutionary characteristics of various races of maize.

McClintock officially retired from her position at the Carnegie Institution in , [3] and was made a Distinguished Service Member of the Carnegie Institution of Washington.

Over the years I have found that it is difficult if not impossible to bring to consciousness of another person the nature of his tacit assumptions when, by some special experiences, I have been made aware of them.

This became painfully evident to me in my attempts during the s to convince geneticists that the action of genes had to be and was controlled.

It is now equally painful to recognize the fixity of assumptions that many persons hold on the nature of controlling elements in maize and the manners of their operation.

One must await the right time for conceptual change. Following Jacob and Monod's Journal of Molecular Biology paper "Genetic regulatory mechanisms in the synthesis of proteins", McClintock wrote an article for American Naturalist comparing the lac operon and her work on controlling elements in maize.

McClintock was widely credited with discovering transposition after other researchers finally discovered the process in bacteria, yeast, and bacteriophages in the late s and early s.

Ac is a complete transposon that can produce a functional transposase , which is required for the element to move within the genome.

Ds has a mutation in its transposase gene, which means that it cannot move without another source of transposase. Thus, as McClintock observed, Ds cannot move in the absence of Ac.

Subsequent research has shown that transposons typically do not move unless the cell is placed under stress, such as by irradiation or the breakage-fusion-bridge cycle , and thus their activation during stress can serve as a source of genetic variation for evolution.

Rosensteil Award in In , she was awarded the Louisa Gross Horwitz Prize from Columbia University for her research in the "evolution of genetic information and the control of its expression.

Most notably, she received the Nobel Prize for Physiology or Medicine in , the first woman to win that prize unshared, [60] and the first American woman to win any unshared Nobel Prize.

She was compared to Gregor Mendel in terms of her scientific career by the Swedish Academy of Sciences when she was awarded the Prize. During her final years, McClintock led a more public life, especially after Evelyn Fox Keller 's biography of her, A Feeling for the Organism, brought McClintock's story to the public.

She remained a regular presence in the Cold Spring Harbor community, and gave talks on mobile genetic elements and the history of genetics research for the benefit of junior scientists.

The McClintock Prize is named in her honour. Martienssen , Jeffrey D. Palmer and Susan R. McClintock died of natural causes in Huntington , New York , on September 2, at the age of 90; she never married or had children.

In , McClintock was the subject of a biography by the science historian Nathaniel C. Comfort's biography contests the claim that McClintock was marginalized by other scientists, which he calls the "McClintock Myth" and argues was perpetuated both by McClintock herself as well as in the earlier biography by Keller.

Keller argued that because McClintock felt like an outsider within her field, in part, because of her gender she was able to look at her scientific subjects from a perspective different than the dominant one leading to several important insights.

For example, when McClintock presented her findings that the genetics of maize did not conform to Mendelian distributions, geneticist Sewall Wright expressed the belief that she did not understand the underlying mathematics of her work, a belief he had also expressed towards other women at the time.

She was intolerant of arrogance She felt she had crossed a desert alone and no one had followed her. Many recent biographical works on women in science feature accounts of McClintock's work and experience.

A recent biography for young adults by Naomi Pasachoff, Barbara McClintock, Genius of Genetics , provides a new perspective, based on the current literature.

On May 4, , the United States Postal Service issued the "American Scientists" commemorative postage stamp series, a set of four cent self-adhesive stamps in several configurations.

McClintock was also featured in a four-stamp issue from Sweden which illustrated the work of eight Nobel Prize-winning geneticists.

A street has been named after her in the new " Adlershof Development Society " science park in Berlin.

Some of McClintock's personality and scientific achievements were referred to in Jeffrey Eugenides 's novel The Marriage Plot , which tells the story of a yeast geneticist named Leonard who suffers from bipolar disorder.

He works at a laboratory loosely based on Cold Spring Harbor. The character reminiscent of McClintock is a reclusive geneticist at the fictional laboratory, who makes the same discoveries as her factual counterpart.
