What has the author S Ann Dunham written?

S. Ann Dunham did not write any published books or academic articles. She was known for her work in microfinance and economic development, and her philanthropic efforts in Indonesia. She also contributed to her daughter, Michelle Obama's, memoir "Becoming", by providing details about her own life and family history.

However, it's important to note that S. Ann Dunham is often mistakenly referred to as an author because of a book called "A Father's Story: Letters from Barack Obama to his Daughter." This book includes a foreword written by S. Ann Dunham, but she did not write the main text of the book.

Therefore, while she played a significant role in contributing to her daughter's memoir, S. Ann Dunham did not publish any books or articles under her own name.
