Joseph Newmark

Joseph Newmark (1799–1881) was a Prussian-American businessman in New York City and Los Angeles and a member of the Newmark family of Southern California. He helped found Jewish congregations in both cities and later became an ordained rabbi.

After immigrating from Prussia to New York City, he was a co-founder there of B'nai Jeshurun. He moved to the West Coast, briefly living and working in San Francisco.

Newmark moved again to Los Angeles in 1854, where two nephews were already in business. He founded Congregation B'nai B'rith in 1862, which was originally an Orthodox synagogue. It later became Reform and is known as the Wilshire Boulevard Temple, the oldest synagogue in Los Angeles. Provided by Wikipedia
