Siegmund "Sig" Spiegel (November 13, 1919 – July 14, 2016) was a Jewish architect, war hero, author, activist, and Holocaust lecturer. A German-American, he fled Nazi Germany to the United States in 1938, following his sister. As an architect he was best known for his extensive work in the New York Metropolitan area.

Siegmund Spiegel was born to German Jews in Gera, Germany, on November 13, 1919, to Jacob and Sara Spiegel.^[1][2] He was one of three children – all of whom escaped Nazi Germany and the Holocaust. When he was 14, he was expelled from school for being Jewish^[3] – and soon thereafter, his parents lost their business and jobs.^[3] In 1938, Spiegel followed his sister to the United States, settling in New York.^[3] His brother fled to Palestine, but his parents chose to stay in Germany, and ultimately were murdered in the Holocaust.^[3]

In 1941, during World War II, he volunteered to be drafted into the United States Army. He served in the 1st Infantry Division, serving in France, North Africa, and Sicily, eventually earning the ranks of Master Sergeant.^[4] He would receive a Purple Heart and Bronze Star for his heroism during the war – in addition to the Croix de-Guerre-Avec Palme and the Chevalier of the French Legion of Honor.^[2]

In the early 1960s, Spiegel designed Syosset Hospital in Syosset, New York; the hospital opened in 1962.^[5][6][7] He also designed an architecturally-significant, drum-shaped bank building in Albertson, New York, shortly thereafter.^[8] In the 1980s, Spiegel designed the relocated facilities for the Village of Freeport, New York's public works department.^[9]

Spiegel also designed a significant number of apartment complexes – and he would eventually begin specializing in designing them.^[10] Among the several complexes he designed were the Flower Hill Garden Apartments (in Flower Hill, New York), Bay Shore Gardens (in Bay Shore, New York), the Cameo House (in Hempstead, New York), and the Chalet Apartments (in Roslyn, New York).^{[10][11][12][13]} He also advocated for converting surplus school buildings into housing for middle class senior citizens.^[14] His private architectural practice was located in East Meadow, New York.^[15]

Spiegel was also a prolific Jewish activist and lecturer on the Holocaust, having lost both his parents in it; he was separated from them when the Nazis deported his mother and father to Poland from Germany around the time of Kristallnacht.^[1][2] He frequently wrote editorials and opinion pieces on architecture and Jewish activism in magazines and newspapers. Spiegel was also the co-founder of the Black-Jewish Coalition of Long Island and of the Nassau County Holocaust Commission, was President of the Long Island Regional Board of the Anti-Defamation League, and was the architect of Nassau County's Holocaust Memorial and Education Center at Eisenhower Park.^{[2][16][17][18]}

In 2012, Spiegel published an autobiography, titled D-Day Plus Seventy Years: A Wartime Odyssey.^[2][19]

Spiegel died in Florida on July 14, 2016, aged 96. He is buried at Arlington National Cemetery in Arlington County, Virginia.^[2][20]
