Joshua Abrass was Born in Berdichev in 1820. He was also known as "Pitshe."
He was considered a child prodigy, and studied with Bezalel Schulsinger in Odessa. Joshua officiated as a cantor in Tarnopol (1840-1842) and in Lvov (1842-1858), and as chief cantor in Odessa (1858-1884). He published one work, Simrat Joh (ca. 1884).
In his memoirs, Cantor Pinchas Minkowski relates the story of the “cantors’ battle” in Odessa between Joshua Abrass and Jacob Bachman, during which the Jewish community in Odessa was divided into two camps: the Pitsists (plural of Abrass’ nickname) and the Bachmanists. For further reading (Hebrew), see: Minkowski, Pinchas. “Misefer Hayyai.” Reshumot 5 (1927): 145-160.
