he Sachsenhausen concentration camp mainly held political prisoners throughout World War II. Prominent prisoners include Joseph Stalin's oldest son Yakov Dzhugashvili, murderer Herschel Grynszpan, Paul Reynaud the penultimate Prime Minister of France, the wife and children of the Crown Prince of Bavaria, and several enemy soldiers and political dissidents. Sachsenhausen was a labor camp outfitted with several subcamps, a gas chamber, and a medical experimentation area. Prisoners were treated harshly, fed sparingly, and killed openly. Those held captive in Sachsenhausen were the men and women which the Third Reich wanted dead, not just because of their religion, but because of their political beliefs and their power over those who listened to them. Today, Sachsenhausen is open to the public as a memorial for the atrocities committed within its walls.
