1880–1941
A Dutch philosopher, jurist, and outspoken freethinker, he became known for defending rational inquiry and humanist values in a deeply unsettled era. His life ended tragically in Sachsenhausen in 1941, giving his work an added moral weight.

by Leo Polak
Born in Steenwijk in 1880, Leo Polak studied law and built a career that crossed philosophy, legal theory, and public debate. He became a respected academic in the Netherlands, teaching first in Leiden and later holding a chair in philosophy at the University of Groningen.
Polak was known as a rationalist, agnostic, and active voice in the Dutch freethought movement. His writing and teaching focused on big questions about justice, punishment, ethics, and the place of reason in public life, and he earned a reputation as an independent-minded thinker who was willing to speak plainly.
Because he was Jewish and publicly visible, he was targeted during the Nazi occupation of the Netherlands. He was deported to Sachsenhausen concentration camp, where he died on December 9, 1941. Today he is remembered not only for his philosophical work, but also for the courage and integrity with which he lived.
