Leo Rapp was born in Hof (Bavaria) on May 28, 1924 to the men’s clothing store manager Simon Rapp and his wife Selma née Kann. After Leo was no longer permitted to attend school, he moved to Munich to live with his uncle Paul Kann and learn mechanics. In 1939, he traveled to England on a children’s transport to live with another one of his uncles and his English wife. There, Leo found work in a factory that made airplane engines. In 1947, he immigrated to the United States, where he worked as a machinist and lived with his aunt Rosa Lang née Rapp and her husband Julius. He married Hildegard Kaiser in 1950.

Hildegard Rapp née Kaiser was born on February 6, 1921 in Kassel, Germany, and worked as a nurse in Frankfurt am Main before emigrating. She first came to Sheffield, England with her sister but was sent back after it was found out that she was working without a permit. She was able to leave for England again with the help of a rabbi. She immigrated to the United States in 1947. In the 1950s, she successfully claimed restitution for damages to her education and career advancement.

Rosa Lang née Rapp was born on April 13, 1896 in Pfungstadt, Germany. She married the salesman Julius Lang (born 1881) on December 12, 1938, and they immigrated to the United States in May of 1939. They both became naturalized citizens in 1945.
