Early life and education
Ralph's father was Oliver A. Kekwick (1865–1939) a managing clerk in a firm of ships' chandlers in Royal Albert Dock, London. His mother was Mary E. Price (1868–1958) who, aged 13, was a pupil-teacher at Bromley St Leonard's Church school, Bromley-by-Bow
Bromley, commonly known as
Bromley-by- Bow, is a district in the London Borough of Tower Hamlets in East London, located on the western banks of the River Lea, in the Lower Lea Valley in East London.

(UCL) and his accounts of this excited Ralph and set him for a career in science.
At age 16, Ralph passed the School Certificate sufficiently to make him eligible for university entrance and he began at UCL in 1925, a month before his 17th birthday. He obtained a BSc with first class in chemistry in 1928.
Career
1920s
UCL did not then run undergraduate courses in biochemistry
Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology and ...
but did have a small biochemistry department headed by Prof. Sir Jack Drummond ( FRS 1944). In 1928 Drummond gave a series of open lectures which Kekwick attended and decided as a result to pursue a career in biochemistry. He stayed at UCL doing work which included the hydrogen-ion dissociation curve of the crystalline albumin

which enabled him to spend two years in the United States. He joined Keith Cannan and resumed work on egg albumin and later published two papers in the Biochemical Journal
The ''Biochemical Journal'' is a peer-reviewed scientific journal which covers all aspects of biochemistry, as well as cell and molecular biology. It is published by Portland Press and was established in 1906.

Theodor Svedberg (30 August 1884 – 25 February 1971) was a Swedish chemist and Nobel laureate for his research on colloids and proteins using the ultracentrifuge. Svedberg was active at Uppsala University from the mid 1900s to late 1940s. ...

and the need to protect other equipment from vibration. Kekwick assisted with the installation and in 1937 a Medical Research Council (MRC) grant supported him working at the Lister where he was offered a post. In 1938, Svedberg attended the opening of the new Lister Institute Biophysics Building. A steady flow of research papers based on ultracentrifugal measurements followed and in 1941, in recognition of his contributions to the physicochemical characterisation of proteins, Kekwick was awarded a DSc DSC may refer to:

of which the Lister was a part.
In the summer of 1939 he left for the USA with his wife and daughter (born 1938) to visit his wife's family and attend the Third Microbiological Congress in New York during which war was declared in Europe. His wife and daughter stayed on with her family while he returned to the UK – his wife and daughter did not return until 1944.
1940s
On his return to the Lister he continued experiments on diphtheria antitoxic horse sera. In 1940, Sir Percival Hartley, head of the Medical Research Council Biological Standards Division, raised problems with serum and plasma for transfusion. On storage, sterile human serum developed a haze owing to liberation of lipid from serum lipoprotein

. This was visually indistinguishable from bacterial contamination. A method was found to produce a clear, filterable, stable product.
There was also a need for stocks of dried plasma or serum that could be reconstituted in emergencies. In 1941 Ralph moved to the unoccupied London County Council Serum Institute at Carshalton

to avoid the London bombing. During 1942–43 the ether-freeze treatment of human serum and plasma was expanded and 1,000 litres of serum and 2,500 litres of plasma were produced and used clinically. More work was done on human plasma fractionation between 1944 and 1954.
1950s – retirement
An expanding demand for dried plasma and plasma protein fractions and a new blood products laboratory was built at the Elstree site.
In 1952 Ralph was appointed Reader in Biophysics in the University of London.
The first effective concentrate of human Factor VIII was produced and used successfully and reported in ''The Lancet

In 1966 Kekwick was given a personal Chair in the University of London and was elected a Fellow of The Royal Society (FRS).
