Shoenberg is known for having developed experimental and theoretical principles to study the De Haas–Van Alphen effect to characterize the electrical conduction of metals.

This ensured that he could continue as a research student, working on low-temperature physics in the newly-built Mond Laboratory,[4] and supervised by Peter Kapitza, FRS.

When the half-built helium liquefier was finished, Shoenberg chose the two topics which lasted him to the end of his active life, superconductivity and the De Haas-Van Alphen effect (dHvA).

[3] For most of his career Schoenberg made the dHvA effect into a powerful tool for understanding the behaviour of conduction electrons in metals.

She was a physiology graduate of University College London and worked in Cambridge on tissue culture, at the Strangeways Research Laboratory and elsewhere.
