SAM BEBER DIES; WAS À FINANCIER He Began B'nai B'rith Youth Group While in Law School Special to The New York Times WASHINGTON, Aug. 27- Sam Beber, founder of the B'nai B'rith Youth Organization, which describes itself as the largest Jewish teen-age move- ment in the world, and a Mid- west financier, died in Chicago Wednesday of pneumonia. He was 75 years old. A native of Omaha, Mr. Beber was 22 and a magna cum laude graduate of Creighton Universi- ty's law school in Omaha when he organized AZA (the initials for aleph zadik aleph, the first and last letters of the Hebrew alphabet), as a Jewish boys' counterpoint to the Greek-letter fraternities, which for the most part denied Jews admission. Two years later in 1926, Mr. Beber, serving as the junior member of B'nai B'rith's nation- al board, persuaded the Jewish service organization to assume sponsorship of the program, which, with a girls' division added in 1944, became the B'nai B'rith Youth Organization. Currently, more than 40,000 youngsters are enrolled in its activities. Among its alumni are Leo Cherne, the economist; Henry Denker, the playwright; Representatives Edward Mez- vinsky and Elliott H. Levitas; Tony Martin, the actor, and Carl Bernstein, Washington Post reporter. One of Mr. Beber's earliest disciples, whom he enrolled in AZA, was Philip M. Kutznick, later to serve as president of B'nai B'rith and a United States Representative to the United Nations under PresidentKenne- dy. The two became brothers- in-law and business partners in American Community Builders, which developed Park Forest, Ill. In 1946 as a model planned community. Mr. Beber is survived by his wife, the former Helen Riekes of Omaha; a son, Harley, of Rockville, Md.; two daughters, Mrs. Floyd Abramson of Chica- a go and Mrs. Jerald Kattleman of San Diego, and a sister, Mrs. Paul Landres of Los An les.
