John L. Ransom

Born in Ohio in 1843, he served in the Union Army during the American Civil War as quartermaster of Company A, 9th Michigan Volunteer Cavalry. In 1863 he was captured in Tennessee and imprisoned at the Confederate camp at Andersonville, Georgia, an experience that would shape the work he is remembered for.

His best-known book, Andersonville Diary, grew from the detailed notes he kept about prison life, suffering, and his eventual escape. The memoir has endured as a firsthand account of one of the war’s most notorious prison camps and is still valued by readers interested in Civil War history.

He died in 1919 in Pasadena, California. More than a century later, his diary remains important not because it is polished literature, but because it feels immediate, observant, and real.
