DNA pioneer’s legacy may be worth millions

Christie's

Francis Crick sketched this diagram of the DNA double-helix molecule in a 1953 letter to his son, Michael. "The model looks much nicer than this," the elder Crick wrote.

The descendants of Francis Crick, co-discoverer of DNA's double helix, are likely to receive a seven-figure sum from this week's sales of the late researcher's Nobel Prize and a handwritten letter describing the structure of the DNA molecule but the geneticists who are carrying on Crick's legacy will win a dividend as well.

"We'll probably be giving more money to the Francis Crick Institute than the prize was worth when he got it," mused Michael Crick, the Nobel-winner's eldest child and the recipient of that historic letter back in 1953.

The sales have been timed to take advantage of the 60th anniversary of the double-helix discovery, which was detailed by Crick and American biologist James Watson in a paper published by the journal Nature on April 25, 1953. Their findings opened the way to deciphering the molecular codes that control all of life's processes. The paper's publication date is now celebrated every year as "DNA Day."

Double helix, double sale Crick's legacy is the focus of two million-dollar sales scheduled in New York this week: On Wednesday, Michael Crick's lettergoes on the auction block at Christie's. His father sent it to the 12-year-old at his boarding school in March 1953 just after the researchers worked out the structure of DNA's long, double-helix molecule, but before the Nature paper's publication. "My dear Michael," the letter began, "Jim Watson and I have probably made a most important discovery."

The seven-page letter goes on to lay out the chemical structure of "des-oxy-ribose-nucleic-acid ... called D.N.A. for short." The elder Crick even sketched out the base pairs connecting the molecule's twisted spines.

"As far as we know, it's the first written description of how life comes from life," Michael Crick, now 72, told NBC News.

The letter has been valued at $1 million to $2 million. Michael Crick and his wife, Barbara, will receive half of the proceeds. The other half will go to the Salk Institute for Biological Studies in California, where Francis Crick worked up to the time of his deathin 2004 at the age of 88.
