Son of Pietro Luigi Bossi, a famous stucco artist active in Saxony, Benigno followed his father to Germany where he learned the art of stucco and collaborated with him. During this period, he became particularly passionate about engraving, especially etching and aquatint. After the end of the Seven Years' War, Bossi returned to Italy and, after a brief stay in Milan, settled in Parma in 1759. Here he began his successful collaboration with the French architect Alexandre Petitot, who in 1753 was called to the French court of Parma. As a painter of neoclassical taste, Bossi painted works for churches in Parma and Colorno, but his activity as a printmaker is what he is most appreciated for. His subjects were drawn mainly from Parmigianino, but also from Correggio, Guercino and Londonio, and he engraved many plates of invention, in which his free sign made his personality manifest.
