By 1960, when Dr. Demerec retired, a proposal had been made to merge the Department of Genetics and the Biological Laboratory to better secure future research funding and more efficient operations. The scientists of the two institutions had begun working cooperatively in the 1930s with the advent of the yearly Symposia and were attending joint weekly meetings and seminar lectures by the mid-1950s. A merger would mean joint administration of the two Labs, but the day-to-day research would continue unchanged.

The page featured above, from the minutes of the Long Island Biological Association meeting on July 15, 1963, announces the completion of the merger and formation of the Cold Spring Harbor Laboratory of Quantitative Biology. Note the new Board of Trustees, comprised of representatives from the nine "participating institutions," along with three additional appointed members, including Barbara McClintock.
