Bruno Zach (sometimes spelled Zack) was born in the town of Schitomir, Ukraine on the May 6, 1891, and died on February 20 1945 in Vienna.  He studied at the Vienna Academy under Hans Bitterlich and Josef Mullner.

Zach worked for various foundries in Vienna.  On some of his most erotic bronzes, he sometimes worked under the name of Prof. Tuch, attempting to remain anonymous..

Subjects of Zach's bronze works include western, orientalist, sporting, animalier, art deco and erotic subjects. Sculptures in bronze and ivory were also cast and carved by him in Vienna.

Bruno Zach worked between the years of 1918 and 1935, reveling in the spirit of Art Deco. Although he executed some graceful moving statues, this Berlin based sculptor devoted most of his energy and talents to the exotic.  Zach loved to render his world of exotic nightlife in his work, especially the prostitutes with whom he loved to socialize. In fact, one prostitute with whom Zach was in love with refused to marry him, leading to the work Hearts.
