Early lifeEdit

Siegfried Ziering was born on March 20, 1928 in Kassel, Germany.[1][2] His father, Isaac Ziering, was Polish.[1] His mother was named Cilly.[1][2] He had a brother, Herman.[1][2] His family was Jewish.[1]

During World War II, his father escaped to England, but his mother and her two sons stayed in Germany.[1][2] In 1941, the Nazis forced them to move to the Riga Ghetto in modern-day Riga, Latvia, alongside 1,000 Jews.[1][3][4] Only twenty survived, including Sigi, his mother and his brother.[1] By the end of the war, they were moved to a prison in Fuhlsbüttel.[1] The Nazis took 10 Jews a day to the Bergen-Belsen concentration camp.[1] They were later moved to the concentration camp in Kiel and forced into slave labor.[1] In 1945, they were rescued by the Swedish Red Cross.[1] Indeed, Count Bernadotte of Sweden had negotiated with Himmler to rescue a few thousand Jews for a few millions of dollars.[3] They were first moved to Sweden and eventually to London, where they met their father.[1][2][4]

Sigi immigrated to New York City with his family in 1949.[1] He received a Bachelor of Science in Physics from Brooklyn College and a master's degree and PhD from Syracuse University.[1]


He started his career at Raytheon, where he worked on nuclear reactors in Boston.[1] He then worked for Allied Research on space projects.[1] In 1961, he was the founder and President of Space Sciences, a government contractor.[1] In 1968, the company was acquired by the Whittaker Corporation for US$1.8 million.[1] He worked as a researcher for Whittaker in California.[1]

After he quit his job at the Whittaker Corporation, he founded fish meal company, but the business failed.[1] Later, he founded Diagnostic Products Corporation, a medical supplies company.[1][2] It was later acquired by Siemens as their subsidiary, known as Siemens Healthcare Diagnostics.[3]

The Judgement of Herbert BierhoffEdit

Sigi wrote a play entitled The Judgement of Herbert Bierhoff.[2] The play is about the destruction of Jewish families during the Holocaust.[2] It is based on the true lifestory of Herbert Bierhoff, a German Jew who poisons his daughter when he hears she is going to be executed by the Nazis.[2] When the Nazis find out what he has done, they kill him too.[2] His widow is sent to the camp in Riga, where she dies of exhaustion.[2] Upon dying, she asks her late husband's friend Shimon to ensure judges see that Herbert's action was merciful in light of the circumstances.[2] Survivors David, Kurt and Esther debate whether Herbert did the right thing or not.[2] The play was analyzed by John K. Roth, a Professor of Philosophy of Religion at Claremont McKenna College in Claremont, California.[2]

In September 1999, the play was first performed at the University of Judaism, later known as the American Jewish University by Jon Voight and Cloris Leachman.[3] In 2008, the play was performed again by students at his alma mater, Syracuse University.[4]

He was a philanthropist to Jewish causes.[1] Indeed, he was President of Temple Beth Am.[3] He also served on the Board of Trustees of the American Jewish University in Bel Air and as co-chair of the Los Angeles section of the United States Holocaust Memorial Museum in Washington, D.C..[3][5] In 1976, with his wife, he endowed a program at the Sheba Medical Center to screen all children born in Israel for hypothyroidism, thus saving more than 2,000 Israeli children from mental retardation.[6]

Personal lifeEdit

He married Marilyn Ziering, a philanthropist, in 1953.[1] They joined Temple Beth Am, a Conservative Jewish congregation in Los Angeles in 1969.[7] The couple had two sons and two daughters:


He died of brain cancer on November 12, 2000.[1]


Shortly after his death, his widow established the Sigi Ziering Institute Exploring the Ethical and Religious Implications of the Holocaust at the American Jewish University in Bel Air.[10] In 2007, she endowed the Sigi and Marilyn Ziering National Center for Newborn Screening at the Sheba Medical Center in Tel HaShomer, Ramat Gan, Tel Aviv, Israel, helping screen Israeli-born children from early signs of mental retardation.[6][11] In February 2013, she also established the US$1 million Marilyn and Sigi Ziering Endowment for the Arts at Shalem College in Jerusalem, Israel.[12] Additionally, she has endowed the Marilyn and Sigi Ziering Brandeis Collegiate Institute (BCI).[13]

The United States Holocaust Memorial Museum has preserved a 12-page letter Sigi Ziering wrote to his father from Sweden on June 24, 1945 as well as a testimony given to the USC Shoah Foundation Institute for Visual History and Education on February 28, 1999, both describing his ordeal at the hands of the Nazis.[14][15] The documents can be read and heard at the museum.[14][15]
