Cold Spring Harbor
After her year-long temporary appointment, McClintock accepted a full-time research position at Cold Spring Harbor Laboratory. Here, 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 1944, 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. In 1945, she became the first woman president of the Genetics Society of America. In 1944 she undertook a cytogenetic analysis of Neurospora crassa at the suggestion of George Beadle, who had used the fungus to demonstrate the one gene–one enzyme relationship. He invited her to Stanford to undertake the study. She successfully described the number of chromosomes, or karyotype, of N. crassa and described the entire life cycle of the species. N. crassa has since become a model species for classical genetic analysis.

Famous quotes containing the words cold, spring and/or harbor:
“The graceless madness of her lips,
Who was the powder-puff of life,
Cannot rouge those cheeks nor warm
His cold corpuscles back to strife.”
—Allen Tate (1899–1979)
“So Spring comes merry towards me here, but earns
No answering smile from me, whose life is twin’d
With the dead boughs that winter still must bind,”
—Dante Gabriel Rossetti (1828–1882)
“What do we want with this vast and worthless area, of this region of savages and wild beasts, of deserts, of shifting sands and whirlwinds, of dust, of cactus and prairie dogs; to what use could we ever hope to put these great deserts, or those endless mountain ranges, impenetrable and covered to their very base with eternal snow? What can we ever hope to do with the western coast, a coast of 3,000 miles, rockbound, cheerless, uninviting and not a harbor in it?”
—For the State of Kansas, U.S. public relief program (1935-1943)
