Ethel Crowell, age 20, died on April 14, 1930, in the office of Dr. Hans Paulsen, from an abortion performed on her that day. Two days later, Paulsen was booked for manslaughter by abortion. The father of the baby, Uriah Denniston, was booked as accessory. Paulson was held by the Coroner for murder by abortion. Denniston wasn't mentioned in the verdict. On September 1, the indictment was quashed. The source notes "Circumstances suggesting judicial corruption."
Ethel's abortion was typical of illegal abortions in that it was performed by a physician.
Keep in mind that things that things we take for granted, like antibiotics and blood banks, were still in the future. For more about abortion in this era, see Abortion in the 1930s.
