Education and career
Megaw studied at Queen's University, Belfast before moving to Girton College to study Natural Sciences in 1926. In her early career Megaw studied crystallography under J. D. Bernal and was awarded her PhD in 1934. Her first book, "Ferroelectricity in Crystals" was published in 1957. It was followed by a second book, 'Crystal Structures: a Working Approach' in 1973.
Following a conversation with Mark Hartland Thomas in 1949 (chief industrial officer of the Council of Industrial Design), Megaw was appointed scientific consultant for Festival Pattern Group the Festival of Britain, 1951.
Legacy and honors
In recognition of her work in determining the structures of ice crystals, Megaw Island in the Southern Ocean is named for her. Megawite (CaSnO3), a perovskite-group mineral, is also named after her.
In 1989, Megaw became the first woman to receive the Roebling Medal of the Mineralogical Society of America.
