Executive Board Directors

Yaakov Riz, Founder
Yaakov Riz, Photo Credit: Len Friedman

Yaakov Riz was born in Lutzk, Poland, on July 22, 1922. When the Nazis invaded his town, his entire family was sent to Auschwitz, where all, except his brother, perished. Yaakov escaped to Russia. He spent six years (1940-1947) in a Russian concentration camp in Siberia. When the war ended, he was repatriated as a Polish citizen and then went to Israel, where he fought in the War of Independence in 1948. He came to the United States in 1952. From 1956 to 1984, he was principal and teacher for the Workman’s Circle School. In 1961 Yaakov created a Holocaust exhibit in his basement. For a number of years, many people followed Yaakov’s belief that children must be taught the horrors of the Holocaust and people must never forget. Thus, in 1975 the Jewish Identity Center was formed and incorporated.


Sheila Riz and Iona Riz
Sheila Riz and Iona Riz

Sheila (nee Hoffer) Riz was born in Bensonhurst, NY, on April 18 ,1932. Nearly her entire family would gather for Shabbat at her Bubbie’s house, eating and laughing, surrounded by the smells of baked challahs and strudels. In 1951, she flew to Israel on an adventure and met Yaakov Riz. He was to be the love of her life. She described him as a handsome and gallant gentleman with quaint European manners. Even though they did not speak a common language – Yaakov spoke Yiddish and Hebrew and Sheila spoke English – they recognized in each other a soulmate and life partner. Together they had three children and three grandchildren. In 1975 she supported the move of our Holocaust museum to her home’s basement. Yaakov always said that, were it not for Sheila taking care of all the worrisome details of life that he did not have the patience to deal with, he would not have been free to pursue his dream of educating children about the Holocaust. Sheila was a hard worker who never complained, and faced life with integrity and honesty, and never flinched in the face of adversity. She had a strong sense of who she was, and held commonsense values and principles that guided her through her life.

Chuck Feldman, PresidentChuck Feldman has a BA and MA from the University of Pennsylvania in American Government. He has taught Political Science at Temple University and the Philadelphia Community College. In addition, he has taught the Current Events class at KleinLife for 30 years.

Chuck met Yaakov because his ice cream parlor was around the corner and Yaakov was a frequent customer. In 1980 Chuck, enamored with the museum volunteered and two years later, he became President. Chuck is married to Paula Weiss, Esq and has three children.
