Who is Wilhelmina Vautrin from The Rape of Nanking and what is their importance?

Wilhelmina Vautrin was the head of the Education Department and dean of studies at Ginling Woman's Arts and Science College in Nanking at the time of the Rape. Vautrin kept a diary through her entire ordeal that told harrowing tales of rape, murder, and violence. When many of the faculty fled the school, Vautrin became the acting head of the institution and for days spread the word that the area would be a haven for Chinese women. Thousands responded to the point where there were women on the lawns, and shoulder to shoulder in the rooms.
