[5][1] Beck took time away from her career to care for her mother who was seriously ill. She then worked in general practice in Wrexham before returning to the Royal Free as Surgical Registrar from 1932 to 1936.

[5] Beck chose to specialise in neurosurgery and trained under Hugh Cairns at the Radcliffe Infirmary in Oxford, where she also acted as a general surgeon providing treatment to injured soldiers during the war.

[6] In 1943, Beck was appointed consultant neurosurgeon at the Elizabeth Garrett Anderson and the Royal Free, but war damage meant that she was unable to establish her new department.

In 1944, she was sent to Chase Farm Hospital, where she took charge of air-raid casualties with head injuries and notably performed a lengthy operation that saved a nurse whose brain was protruding from her skull and was expected to die.

[5] Beck then went to Bristol as Regional Adviser in Neurosurgery to the emergency medical service for south-west England, working at the Burden Neurological Institute and travelling to consult around the area.

Beck was recipient of an English Heritage blue plaque in 2024, alongside Christina Broom, Irene Barclay and Adelaide Hall.
