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:
“Are you cold too, poor Pleiads,
This frosty night?
Yes, and so are the Hyads:
See us cuddle and hug, says the Pleiads,
All six in a ring: it keeps us warm:
We huddle together like birds in a storm:”
—Robert Graves (18951985)
“Is it a new spring star
Within the timing chill,
Talking, or just a mime,
That rises in the blood
Thin Jack-and-Jilling seas
Without the human will?”
—Allen Tate (18991979)
“When was I ever anything but kind to him?
But Ill not have the fellow back, he said.
I told him so last haying, didnt I?
If he left then, I said, that ended it.
What good is he? Who else will harbor him
At his age for the little he can do?”
—Robert Frost (18741963)
