Martin Ernest Dannenberg was an American insurance executive. He served as chairman of the Sun Life Insurance Company for five decades. While serving as a counterintelligence officer in the United States Army during World War II with the U.S. Third Army, Dannenberg discovered an original copy of the Nuremberg Laws signed by Adolf Hitler. The document was in the personal possession of General George S. Patton and held by The Huntington Library until it was turned over to the United States National Archives days after Dannenbergs death.
Dannenberg was born on November 5, 1915, in Baltimore, where his family had been part of the founding of Har Sinai Congregation in 1842. After completing high school, he worked for the Sun Life Insurance Company as a clerk in the records department and earned his bachelors degree from Baltimore City College. He later attended Johns Hopkins University and the University of Baltimore School of Law at night, but dropped out after his boss showed him former lawyers who were forced to sell fruit on the street during the Great Depression. After completing his military service, Dannenberg returned to work for Sun Life, becoming the company chairman until his retirement in 1987. During his tenure, he undertook a number of acquisitions that turned the company into a major national insurance industry competitor. He was active with the Boy Scouts of America and had been honored as the oldest living Eagle Scout in Maryland.
