The Ovitzes—like many other camp inmates—were subjected to various tests. Mengele's physicians extracted
bone marrow and pulled out teeth and hair to find signs of
hereditary disease. They poured hot and cold water in their ears and blinded them with chemical drops. Gynecologists inspected the married women.
Eighteen-month-old Shimshon Ovitz was put through the worst ordeals because he had taller parents and was prematurely born; Mengele drew blood from the veins behind his ears and from his fingers on a daily basis often causing weakness. The Ovitzes also witnessed two newcomer dwarfs being killed and boiled so their bones could be exhibited in a museum. Mengele also filmed them; this film was not found after the war, and it is possible that he kept it when he fled.
