Dorothy Crowfoot met a young man named Thomas Hodgkin and the couple was married a short time later.
World War II began shortly after her marriage but Dorothy’s work was not interrupted.
The war led to Dorothy’s first major scientific success and her discovery was to have farreaching consequences.
A British scientist named Alexander Fleming had several years earlier discovered a special mold that could destroy harmful bacteria.
The mold was called penicillin and grew naturally.
Doctors knew that penicillin could cure diseases caused by bacteria yet it was available in such small quantities that it could not be used in widespread applications.
It was a medical dream to learn to “grow” penicillin artificially in a laboratory for then it could be manufactured in large quantities.
Dorothy started to work on this problem but it proved to be very difficult to crystallize the penicillin molecules.
Dorothy and her assistants analyzed the structure of penicillin using the X-ray diffraction technique and the discoveries they made changed the history of medicine.
Penicillin and similar drugs can now be manufactured in large quantities but this breakthrough could not have been achieved without the work of Dorothy Crowfoot Hodgkin’s team of scientists.
