Johanna Müller-Hermann (1868–1941) was an Austrian composer and conductor, notable for her contributions to early 20th-century classical music. Primarily associated with the genres of orchestral and choral music, she was one of the few prominent female composers of her time, which was a male-dominated field. Müller-Hermann studied at the Vienna Conservatory and later gained recognition for her compositions that often blended Romantic and early modernist styles. Among her notable works are "The Day of Judgment" (1911), a choral work, and several orchestral pieces, including symphonic works that reflect her innovative approach to harmony and structure. Despite her talent, Müller-Hermann faced challenges in gaining widespread recognition during her lifetime, largely due to the societal norms regarding women in music. However, her efforts opened doors for future generations of female composers. In recent years, her works have been revived and performed more frequently, contributing to a reassessment of women's contributions to classical music. Through her compositions, she has had a lasting impact on the visibility of female musicians in the classical genre.
