from a letter to Bronislaw Malinowski, 1938

Witkacy committed suicide on 18 September 1939 as the Russian army entered eastern Poland, countering the Nazi invasion from Germany. In a forest he took sleeping pills, woke up, then cut his wrists with a razor. His last words were 'I won't go on living as less than myself'.

Witkacy's fianceé Jadwiga Janczewska had committed suicide using his gun in 1914.
