[Penicillin: just in time].

In the attic of his home the author found papers concerning the case history of a woman who in the first days after the liberation, in April-May 1945, suffered from a severe form of puerperal sepsis. The woman recovered completely after treatment with a totally new drug: penicillin, obtained from the medical supplies of the allied British forces. She probably was the first patient treated with this antibiotic in the Netherlands.
