The Hyers Sisters, Anna Madah (ca. 1855 – 1929) and Emma Louise (ca. 1857 – 1901), were singers and pioneers of black musical theater. With Joseph Bradford and Pauline Hopkins, the Hyers Sisters produced the "first full-fledged musical plays... in which African Americans themselves comment on the plight of the slaves and the relief of Emancipation without the disguises of minstrel comedy." Their first play was Out of Bondage (also known as Out of the Wilderness).
Their father, Samuel B. Hyers, came west to Sacramento, California with their mother, Annie E. Hyers (née Cryer), after the Gold Rush. He made sure his daughters received both piano lessons and vocal training with German professor Hugo Sank and later opera singer Josephine D'Ormy and they performed for private parties before making their professional stage debut at on April 22, 1867 at Sacramento’s Metropolitan Theater. Anna was a soprano and Emma a contralto. Under their father’s management, they embarked on their first transcontinental tour in 1871. On August 12, 1871, they performed in Salt Lake City to much acclaim.
They were later called "a rare musical treat" by Saint Joseph, Missouri’s Daily Herald and earned equal praise in Chicago, Cleveland, and New York City. Their tour reached Worcester and Springfield, Massachusetts, as well as New Haven and Providence. They visited Boston, which was known to be extremely critical of new acts, and were also well-received, performing in the 1872 World Peace Jubilee which was one of, if not, the first integrated major musical production in the country.
