Yitzchok Alster
Yitzchok Alster is a Jewish educator and composer of Jewish liturgical melodies, best known for his contributions to the musical culture around Yeshiva Chaim Berlin in the 1950s and 1960s. A close student of Rabbi Yitzchak Hutner, he described niggun as central to spiritual life.
Musical work
Alster composed a number of melodies that became widely sung in yeshiva and synagogue settings. Among the most enduring is Yedid Nefesh, a setting often sung at shalosh seudos, which he composed as a young student in the Catskills.
In 1960, Yeshiva Chaim Berlin released a record titled Torah Lives and Sings, which included several of Alster's compositions. He later explained that the project reflected Hutner's view of niggunim as a tool for memory and spiritual elevation, and as a way to preserve the character of a particular era.
Educational leadership
Alster founded the Yeshiva of Pittsburgh in 1967 and later established educational frameworks for working professionals in New York. He moved to Israel in 2004, where he helped establish a kollel for English-speaking scholars.
