Woods CSAC 64/2/79 DESCRIPTION OF THE COLLECTION The material was received from Mrs. A. Woods (widow), and from Woods's colleagues and secretary at Oxford. The letters from P. Erlich to Sir Paul Fildes (D.1) were received from Miss A. Pearce-Gervis. The collection includes a full set of Woods's laboratory notebooks for his work in Cambridge 1933-39 on bacterial metabolism (B.3 - B.19), and less complete but still useful material documenting his later research at Oxford on folic acid and By2 (B.27 - B.35). There is very little correspondence, most of which was des- troyed after Woods's death in 1964. Woodsis best known for his determining in 1939 of p-aminobenzoic acid (PAB) as an anti-sulphanilomide factor; this work is documented inC.15-C. iv; which assembles the original laboratory notes and other contemporary records as they were used by Woodsfor a historical lecture at Oxford in 1961 - Seealso B.21.

Thereis also a little material relating to Sir Paul Fildes FRS, to whom in 1939 Dr. Stephenson recommended Woods to work at the M.R.C. Unit in Bacterial Chemistry at the Bland-Sutton Institute, Middlesex Hospital, where his work on PAB wascarried out. nately, none of Fildes's own papers have been traced, but D.1 includes three letters written to Fildes by Paul Erlich in 1912, on Salvarsan. munications refer distantly to the clinical trials of Erlich's new drug Salvarsan (606) in the treatment of syphilis, conducted by McIntosh and Fildes, and sub- sequent publications and controversy.

Woods's arrival in London and kepi up to c.1945, Woodsleft Cambridge in April 1939 to work with Fildes at the above Unit.

Woods CSAC 64/2/79 Laboratory notebooks and working papers Large loose-leaf binder, with some loose pages, containing details of experiments on various inhibitors of micro- organisms, April 1939-February 1941. Though several entries refer to p-aminobenzoic acid, on which Woods continued to work until early 1940, these experiments mark the conclusion of his work on PAB and the start of his 'war work' - begun in London and later carried on at Porton. Most of the entries bear a War Office numberas well as a date and description. Included on a loose page is Woods's tabulated information on the dates on which experiments were carried out. The entry for Biotin (5.8.40.) is interesting in being accom- panied by correspondence requesting and accompanying samples from J. Williams (Texas) and J.R. Porter (lowa), July 1940.
