What is the name of the laboratory at Cambridge where Watson and Crick worked?

The laboratory at Cambridge where Watson and Crick worked was the Cavendish Laboratory. Francis Crick was already working there in an MRC research unit led by Max Perutz when James Watson arrived from the United States in 1951.

The Cavendish provided an important setting for their DNA research. Watson and Crick combined model-building with X-ray diffraction evidence produced at King's College London, including work by Rosalind Franklin, Raymond Gosling, and Maurice Wilkins. Their double-helix model was published in Nature on 25 April 1953.

The laboratory was founded in Cambridge in 1871 and became famous for physics discoveries, including the electron. Its director during the DNA breakthrough was Sir Lawrence Bragg, a pioneer of X-ray crystallography. Watson, Crick, and Wilkins received the 1962 Nobel Prize in Physiology or Medicine for their work on nucleic-acid structure.
