Joseph Smith would occasionally require the services of fellow first presidency member and doctor, John C. Bennett, to perform abortions for some of his girlfriends. Sarah Pratt (wife of LDS apostle Orson Pratt) writes:
“One day they came both, Joseph and [Doctor] Bennett, on horseback to my house. Bennett dismounted, Joseph remained outside. Bennett wanted me to return to him a book I had borrowed from him. It was a so-called doctor-book. I had a rapidly growing little family and wanted to inform myself about certain matters in regard to babies, etc., – this explains my having borrowed that book. While giving Bennett his book, I observed that he held something in the left sleeve of his coat. Bennett smiled and said: ‘Oh, a little job for Joseph; one of his women is in trouble.’ Saying this, he took the thing out of his left sleeve. It was a pretty long instrument of a kind I had never seen before. It seemed to be of steel and was crooked at one end. I heard afterwards that the operation had been performed; that the woman was very sick, and that Joseph was very much afraid that she might die, but she recovered.”
