Talmudic scholar in 11th-century Germany, often cited by Rashi and other Rishonim. He was also a chazzan, which earned him the appellation "Shliach Tzibur", and composed many piyutim. He is most known for the piyut "Akdamut Milin" which is recited by most congregations before the Torah reading on the festival of Shavuot.
