Born in Lodz, Poland, Binyomin was the oldest son of a Radoshitzerchassidic family. His mother passed away when he was eight years old, and he left Europe by himself in 1907 based on correspondence with a friend who preceded him to America. He first peddled from a pushcart, until he had made enough money to rent a store. Within less than two years he had his own houseware business; the business still exists. Binyomin married Bluma Weberman.
He moved to Williamsburg, Brooklyn, where he and his friend, Louis Dershowitz, wanted to open a yeshiva for boys. At that time, the few yeshivos that existed in the United States — Yeshivas HaRav Yaakov Yosef, Etz Chaim Yeshiva, Yeshivas HaRav Shlomo Kluger — were all in the Lower East Side of Manhattan. Wilhelm envisioned a yeshiva that taught secular studies in the afternoons. Wilhelm had to overcame large opposition to his type of yeshiva. Most parents did not want to send their children to yeshiva. There was also opposition from the other side. Some parents held that a yeshiva should be purely for Jewish studies. In the end he prevailed and founded what would become known as 'the mother of all American yeshivos' - Yeshiva and Mesivta Torah Vodaath. A major breakthrough was the later recruitment and hiring of a yet unknown man, who Wilhelm uncovered, Rabbi 'Mr.' Shraga Feivel Mendelowitz. Together they built the first mesivta in New York and spurred the creation of Torah Umesorah. Binyomin Wilhelm was instrumental in the founding and stabilization of the first Bais Yaakov schools for girls and many other organizations. Wilhelm was active in Torah Vodaas until his 80s, when he moved to Israel in 1968. There, he founded a network of afternoon programs for Sephardic youth in developing areas, which was to strengthen their commitment to Judaism. He called the network Mifal Torah Vodaath. This innovative program was one the very first Jewish outreach programs created.
Belsky, Hershkowitz, Gewirtz branches
The Wilhelm family went on to become known as leaders on the Jewish communal scene in communities across the country and beyond. Their daughter Chana married Rabbi Berel Belsky and in 1970 moved from Williamsburg to Kensington.; their son Yisroel Belsky, years later, became a rosh yeshiva of Yeshiva Torah Vodaath. The Wilhelm's daughter Lea married Yona Zev Hershkowitz. Claire married Berney Gewirtz.
