For many years, Esther Bloom was a generous yet anonymous supporter of Emanuel Synagogue. A graduate of Central High School in Oklahoma City, she received a bachelor's degree in education from the University of Oklahoma. Following her death in 1997, she left her estate to Emanuel Synagogue in memory of her parents, Anne and Isaac Bloom, to support the education of children in the congregation. In 2001, Emanuel Synagogue transferred those fund to create a permanent endowment at the Oklahoma City Community Foundation.
In 1885 at just 18 years old, Isaac Bloom became a Russian immigrant searching for a better life in America. As a traveling peddler, he found his way to Indian Territory where he met and soon married Annie Bloom. The couple settled in Holdenville, Oklahoma, where Isaac opened a general store and they began raising their family. When their youngest was five years old, they relocated to Oklahoma City so they could teach their children Jewish values and traditions.
The family quickly became instrumental members of Emanuel Synagogue, raising money for a Hebrew teacher and organizing synagogue and community events. Following Isaac's death, Annie led the effort to establish Emanuel Hebrew Cemetery. When her mother became too ill to continue her work, Esther Bloom took over her role as a Sunday school teacher and advocate, developing her own passion and love for the Hebrew school and its students.
