B.P.
Since Selma had no children but many nieces, nephews and friends, figured on posting here since this is the top page search result entering her name.
Read Selma's book, The Day I passed the Statue of Liberty (1989). In the book she said she was writing her autobiography. If she did it was never published. If someone has the manuscript, please post here that you are in possession of it or know where it is. We would be interested in publishing it.
