Hertha Ernestine Pauli was a journalist, writer and actor. She wrote books about Alfred Nobel and the Statue of Liberty. Her books for children, including "Silent Night: The Story of a Song," published in 1943, were particularly successful.
Sojourner Truth ended up in Battle Creek Michigan where her bones rest. So why did I not hear of her as a child growing up in Detroit. I went to an all white catholic school for elementary school and a less than 1% black catholic high school. Maybe I don't remember the teaching of racial issues in the US, other than a skimming of the basics. I remember the riots of 1967. My sister wedding was not allowed in a hall, so it was at home at 7 mile and Hayes. Tanks rolled down the street, people were checked at 8 mile entering and leaving the city. The cops stopped to tell the family to not violate the curfew. My sister in her gown and our brother in his air force uniform probably had as much to do with them not arresting the family for a gathering, but maybe those white faces and blue eyes helped.
Sojourner Truth was a contemporary of Frederick Douglas. She managed an interview with Abraham Lincoln while he was in the White House . Interesting life but set in an era where spiritualism was emphasized so required reading through more of that than her influence on helping the slavery question and the right for women to vote.
If you read The Hiding Place by Corrie ten Boon it is similar in flavor about a woman's faith in God at a timing of harshness in history's paths.
