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:
“Half-opening her lips to the frost’s morning sigh, how strangely the rose has smiled on a swift-fleeting day of September!
How audacious it is to advance in stately manner before the blue-tit fluttering in the shrubs that have long lost their leaves, like a queen with the spring’s greeting on her lips;
to bloom with steadfast hope that, parted from the cold flower-bed, she may be the last to cling, intoxicated, to a young hostess’s breast.”
—Afanasi Fet (1820–1892)
“For winter’s rains and ruins are over,
And all the seasons of snows and sins;
The days dividing lover and lover,
The light that loses, the night that wins;
And time remembered is grief forgotten,
And frosts are slain and flowers begotten,
And in green underwood and cover
Blossom by blossom the spring begins.”
—A.C. (Algernon Charles)
“It is said that the British Empire is very large and respectable, and that the United States are a first-rate power. We do not believe that a tide rises and falls behind every man which can float the British Empire like a chip, if he should ever harbor it in his mind.”
—Henry David Thoreau (1817–1862)
