Zygmunt Kaczkowski

Zygmunt Kaczkowski (1825–1896) was a Polish writer, independence activist, and an Austrian spy. He was convicted in 1864 of espionage by an underground court in the January Uprising. There is a consensus that this accomplished writer is today a forgotten figure of Polish literature, virtually erased from national consciousness (one of the "absent greats"wielcy nieobecni).
