Rabbi Chaim Tzvi Mannheimer was born in 1814. He was educated at the yeshiva of the Chasam Sofer.
His first rabbinical position was at Shutelsdorf. As this was a relatively small city, Rabbi Chaim Tzvi found time for learning and opened a small yeshiva in the city as well. Later, he became Rabbi in Verboi.
