Gwyn Macfarlane. Two years later, she began to study plasma concentration and selective extraction of
factor VIII

By 1953 she had devised a technique to extract and concentrate bovine factor VIII that was 8000 times stronger than human plasma.
In 1959 she was working on the preparation of human coagulation factors at the
