Elisabeth Becker was born in Neuteich (Nowy Staw), Poland on 20 July 1923 to a German family. In 1936, she joined the NSDAP and BDM .

In 1938, she became a cook in Danzig. In 1939, the Germans marched into the city and Elisabeth was accepted into the "master race". In 1940, Elisabeth began working for the firm "Dokendorf" in Neuteich. She worked there until, in 1941, she became an agriculture assistant in Danzig.

In 1944, the Soviets were near the area and the Germans needed more guards at the nearby concentration camp at Stutthof, so they called up Elisabeth. On September 5, 1944, Elisabeth arrived at Stutthof to begin her training to be an Aufseherin. She eventually worked in the women's camp in Stutthof at SK-III. the younger women prisoners' camp.

On January 15, 1945, Elisabeth fled the camp and went back home to Neuteich. Polish police officers arrested the former SS woman on April 13, 1945, and sent her to prison to await trial. On May 31, 1946, the Stutthof Trial began in Danzig. There sat five former SS women and several kapos. Because Elisabeth had selected women and children for the gas chamber at Stutthof, she was sentenced to death. She sent several letters to the Polish president, Boleslaw Bierut, asking for a pardon because her deeds were not as severe as Gerda Steinhoff's or Jenny Wanda Barkmann's, but to no avail. She was publicly hanged on 4 July, 1946, at Biskupia Gorka Hill along with the other SS overseers and kapos.
