[2] She spent a year at Queen's University, Belfast[2] before moving to Girton College, Cambridge to study Natural Sciences in 1926.

In 1935 Megaw co-published with Bernal an influential method for fixing the position of hydrogen atoms known as the Bernal-Megaw model.

[2] In 1945 Megaw returned to working with Bernal, now at Birkbeck College in London, for a year before taking a post at the Cavendish Laboratory in Cambridge.

She became the prime scientific mover in the group which put crystallographic images in the hands of industrial designers for them to use in products which were displayed at the Festival and in some cases beyond.

[10] In 1976, Megaw gave a collection of fabric samples from the Festival of Britain along with a souvenir guide-book to the Science Museum in London.
