BROOKLYN - A prominent Brooklyn Jewish leader has passed away at the age of 79.

Rabbi Binyomin Klein served his community in Crown Heights for nearly 50 years. He was the longtime aide to the Lubavitcher Rebbe.

His funeral procession was held Friday at the Chabad on Eastern Parkway.

Klein was among the founders of Yeshivah Gredolah in Australia and New Zealand.

Throughout his illustrious career, Rabbi Klein traveled to South America and Cuba to bring Jewish literature and inspiration.

Klein was influential with Israel's political, military and security leaderships, developing deep connections with leaders who would often seek his guidance and counsel.

Those who knew Rabbi Klein best say that he will be truly missed, but his legacy will live on.

"Rabbi Klein leaves a legacy of a very dedicated, humble aide as secretary of the Rabbi. Someone who cared for people and made a lasting impact on the lives of many people," says Rabbi Moshe Kotlarsky.

According to reports, Rabbi Klein died in his sleep.
