Adolf Lambertz was born on September 2, 1879, in Kempen (Krefeld district). He converted from Judaism to Protestantism in 1927, but the Nazi regime still pressured his employer. Working at Heckel since 1912, he was eventually demoted. On November 10, 1938, he was arrested as a Jew and sent to Dachau after four days in Saarbrücken prison. Released on December 21, 1938, he returned to work at Heckel. After the U.S. troops entered Hassel in March 1945, Lambertz was appointed mayor from March 24 to December 31, 1945. He later resumed work as an engineer and died on July 18, 1967, in Hassel.
