Alan Hart

March 31 is the Transgender Day of Visibility so in honor that, I am re-sharing the story of Alan Hart, which I recently learned about from this blog post.
Before tuberculosis was treatable, Hart developed a protocol using chest X-rays to identify carriers before they showed visible symptoms. The interventions he designed saved thousands of lives. X-rays are still used today in diagnosis. Hart also wrote four novels which were well-received.
