Marion Blackett was 26 when she began the research for the book, in 1926, and 34 when she published it, under the pseudonym Joanna Field. She had completed a degree in psychology and physiology, in 1923, and soon after started working for the National Institute of Industrial Psychology, headed by Charles Samuel Myers, collecting data from various factories and industrial workplaces across England.

She would eventually begin training with the British psychoanalysis group
