After the death of her first husband, Gordon Cunningham, she married the eminent surgeon Claude Frankau (1883–1967) in 1935.
[5][6][7][8] During the Second World War, she worked at Cambridge University's Psychological Laboratory on the use of dietary supplements to improve the physical performance of servicemen.
[9] In the early 1950s she researched the use of subconvulsive electroshock therapy treatment for alcoholism.
[13][14][15] Her readiness to prescribe controlled drugs is credited with single-handedly addicting many British people.
[17] After Frankau's death in 1967, John Petro largely took over her practice as a prescriber to heroin addicts; he was struck off in 1968.
