Two copies of undated X-ray diffraction photograph of herring sperm DNA

Photographs, glass slides and negatives of B form DNA optical transform patterns, and images of dotted outlines of the spots on the B form pictures, obtained with an optical diffractometer developed by Henry Lipson (1910-1991). Clive Hooper, Bill Seeds and Alec Stokes wrote an account of their adaptation of the Lipson method for macro molecules such as DNA, ‘Photographic Preparation for the Large Molecules for the Lipson Diffractometer’, published in Nature, Volume 175, 16 Apr 1955, p679-681. File also includes photographs of early models of DNA structure, [1950]. Original file title ‘File Lipson data’

Maurice Wilkins’ laboratory research notebook containing notes on experiments and methodologies, diagrams, statistical tables, graphs, chemical structures and equations relating to DNA research, including: initial tests on DNA obtained by Erwin Chargaff from balantidium coli (B Coli) and wheat germ; plots of Bessel Functions, including statistics and a ‘Bessel waves’ diagram; diagram and sketch for the design of Wilkins’ new slot plate camera; notes on experiments conducted in Rio de Janeiro, Brazil, and Naples, Italy; notes on a interference microscope study of pollen grains, 1952, with sketches of microscope images; DNA weighing experiments testing the Watson and Crick DNA model. Also notes on the history of the discovery of the structure of DNA written by Wilkins 1975-1997. Original volume title ‘DNA Wilkins 1951. Early x-rays 51-52’

Maurice Wilkins’ laboratory notebook containing notes, diagrams and data relating to DNA research, including: notes by William Etienne (‘Bill’) Seeds on tissue sample results, and on the Burch reflecting microscope (possibly relating to Seeds and Wilkins’ article, ‘a simple reflecting microscope’, published in Nature, Aug 1949); notes relating to research on Tobacco Mosaic Virus (TMV) crystals, 1949, including notes on Alexander Stokes’ theory of a helical structure; early microscope-based analysis of calf thymus DNA fibres supplied by Rudolf Signer, including data from birefringence experiments. Loose items include graphs, notes on experiments, specifications for a microscope and later photocopy notes, on the history of DNA research. Original volume title ‘Wilkins 1947 1951’
