Abram L. Sachar was a pioneer and founder of the Hillel movement on American college campuses. He first became involved with the organization during his teaching career at the University of Illinois. Sachar served as Director of the Illinois sector from 1929 to 1933, and would go on to serve as National Director from 1933 to 1947. During his tenure, Hillel grew from nine to nearly 200 campus chapters throughout North America. Upon retiring as National Director in 1947, Sachar was named the Chairman of the National Hillel Commission. In this capacity, and later as Honorary Chairman, he continued to be active in support, activities, and fundraising for Hillel.
Sachar also served as President of the B'nai B'rith Youth Organization (BBYO) from 1945 to 1948. Founded in 1924, the BBYO is the largest and oldest international Jewish youth organization in the world. It is composed of the Aleph Ztadik Aleph for boys (AZA), and the B'nai B'rith Girls (BBG). The BBYO's mission is to offer social, educational, and leadership opportunities to Jewish teens from seventh through twelfth grade. Each chapter is required to offer programs in the areas of community service, social action, Jewish heritage and culture, athletics, and socialization. These programs are planned and implemented by the organization's youth members.
