Rosemary Fowler

Born in Suffolk in 1926, Brown grew up in Malta, Portsmouth and finally Bath, as her family moved to follow the postings of her father, a Royal Naval engineer.

[3] After graduating from Bristol, Brown became a doctoral researcher in the group of Cecil Powell, a British physicist and pioneer in the use of nuclear emulsion coated plates to investigate cosmic rays entering the Earth's atmosphere.

[5] Working alongside her fellow PhD student and future husband Peter Fowler, Brown studied the tracks left on stacks of photographic plates that were exposed to cosmic rays at the Sphinx Observatory, a high-altitude laboratory at Jungfraujoch, Switzerland.

[9] She never completed her doctorate, but continued to assist her husband while raising their three daughters[4] – one of whom, the geophysicist Mary Fowler, became Master of Darwin College, Cambridge.

[1][2] The university stated "Rosemary's discovery of particles and contribution to our understanding of fundamental interactions in physics has often been attributed to Powell and her husband Peter Fowler, and this honorary degree acknowledges the vital role she has played in science.
