About Willem van Wijk (Hoornik)
"In Letter 192 Vincent wrote to Theo about his first meeting with Sien:
Last winter I met a pregnant woman, deserted by the man whose child she was carrying. A pregnant woman who walked the streets in the winter--she had her bread to earn, you'll know how. I took that woman on as a model and have worked with her all winter. I couldn't pay her a model's full daily wages, but I paid her rent all the same, and thus far, thank God, I have been able to save her and her child from hunger and cold by sharing my own bread with her"
