What Is Life? can be viewed as a well-reasoned theoretical prediction of what biologists should have been looking for during their search for genetic material. Both James D. Watson, and Francis Crick, who jointly proposed the double helix structure of DNA based on X-ray diffraction experiments by Rosalind Franklin, credited Schrödinger's book with presenting an early theoretical description of how the storage of genetic information would work, and each independently acknowledged the book as a source of inspiration for their initial researches. The book is based on lectures delivered under the auspices of the Institute at Trinity College, Dublin, in February 1943 and
Maurice Wilkins deduced from her X-ray diffraction data. Watson and Crick published their proposed DNA double helical structure in a paper in the journal "Nature" in April 1953. In this paper Watson and Crick acknowledged that they had been "stimulated by... the unpublished results and ideas" of Wilkins and Franklin. The first Watson-Crick paper appeared in "Nature" on 25 April 1953. The members of the Cambridge and King's College laboratories agreed to report their interlocking work in three papers with continuous pagination in "Nature". Sir Lawrence Bragg, the director of the Cavendish Laboratory, where Watson and Crick worked, gave a talk at
