John Simkin. ”Ruth Hale”. Spartacus Educational. https://spartacus-educational.com/USAruth_hale.htm. Läst 29 november 2019. ”My best friend died yesterday. I would not mention this but for the fact that Ruth Hale was a valiant fighter in an important cause. Concerning her major contention we were in almost complete disagreement for seventeen years. Out of a thousand debates I lost a thousand. Nobody ever defeated Miss Hale in an argument.”
