Sandra Cisneros was born in Chicago in 1954 to a Mexican American family. As the only girl in a family of seven children, she often felt like she had “seven fathers,” because her six brothers, as well as her father, tried to control her. Feeling shy and unimportant, she retreated(躲避) into books. Despite her love of reading, she did not do well in elementary school because she was too shy to participate.
In high school, with the encouragement of one particular teacher, Cisneros improved her grades and worked for the school literary magazine. Her father encouraged her to go to college because her thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the university’s Writers’ Workshop, however, she felt lonely----a Mexican American from a poor neighborhood among students from wealthy families. The feeling of being so different helped Cisneros find her “Creative voice.”
“It was not until this moment when I considered myself truly different that my writing acquired a voice. I knew I was a Mexican woman, but I didn’t think it had anything to do with why I felt so much imbalance in my life, but it had everything to do with it! That’s when I decided I would write about something my classmates couldn’t write about.”
Cisneros published her first work, The House on Mango Street, when she was twenty-nine. The book tells about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been used in classes from high school through graduate school level. Since then, Cisneros has published several books of poetry, a children’s book, and a short-story collection.
