EBERLIN, JOHANN ERNST German musician and composer, was born in Jettingen, Bavaria, on March 27, 1702, and became court organist to the prince-archbishop of Salzburg, where he died on June 21, 1762. Most of his compo sitions were for the church (oratorios, etc.), but he also wrote some important fugues, sonatas and preludes, and his pieces were at one time highly valued by Mozart.
