« [Gudrun Bjerring] Parker had worked as a journalist with the Winnipeg Free Press before coming to the NFB in March 1942. Hired as an assistant editor, Parker quickly showed a desire to make her own films. [John] Grierson told her to go find some money. She met with staff from Health and Welfare Canada (known today as Health Canada), and submitted a proposal for a three-film project on the importance of vitamins for the nutrition of women and children. After going back and forth several times, staff at the ministry agreed to fund the project. Parker hired Judith Crawley as cinematographer, and directed three films that were eventually released under one title: Vitamins A, B1, C and D (1943). »
