The two Delbrück Laboratories are the center and south buildings of the plant genetics facility called the Delbrück-Page Laboratory Complex. In 1987, the Page Laboratory was built north of the former Davenport Lab to form the 3-building complex. The infamous CSHL "plate race" is held in front of these buildings at the end of the yeast course every year, in which runners use stacks of Petri dishes as batons in this unique relay race.

For the complete history of the complex, please see the Building Blocks of CSHL pages for the Davenport Laboratory and the Page Laboratory.
