About Siggi Wilzig

Siegbert (Siggi) Wilzig was a survivor of the Holocaust. He arrived penniless in America in 1947 at age twenty-one and, over the following fifty years, became one of the most successful businessmen in postwar America. Wilzig rose to the heights of the predominantly Protestant industries of oil and banking. The engine that drove him forward was a determination to preserve Holocaust memory.

He was a two-time Presidential appointee to the U.S. Holocaust Memorial Museum in Washington, D.C. Wilzig’s life story reveals the tensions and consequences of Holocaust memory and provides a window into the psychology of those who came out of “history’s darkest hour.”
