Quote:
"In March 1937, the GPO Film Unit [General Post Office Film Unit, London, England] employed 31 members of staff directly and 20 contracted staff: ten were women. In general, women were recruited to recognised 'female' roles, notably shorthand typing, cleaning and negative cutting. [...] Almost all senior positions at the Unit (directors, managers and sound technicians) earning over £5 per week were filled by men. Evelyn Spice, a director, earning £8 10s., was the exception."
