Vsevolod Garshin. Portrait by Ilya Repin.
Vsevolod Garshin was a Russian writer of mainly short stories, and is often compared to Dostoevsky due to his empathetic and earnest style. During the Russo-Turkish War, he was conscripted despite his pacifism, and was wounded in Bulgaria. His experiences in the war left him scared both physically and mentally, and he eventually committed suicide when he was 33.
He wrote one of my very favorite short stories, Красный цветок (The Red Blossom), in which a lunatic becomes convinced that all the evil of the world is contained in a small poppy outside of his cell in an asylum, and it becomes his singular goal to pluck the blossom before the evil spreads.
