Morrison Foster (June 10, 1823 – May 14, 1904) was the older brother, business agent and biographer for Stephen Foster, a composer and lyricist of early American music. When Stephen Foster died at age 37, Morrison continued to manage Stephen's estate and acted as a mediator between music publishers and Stephen Foster's wife and daughter. Documents demonstrate his correspondence with publishers in his receipt of royalty payments on behalf of Stephen's heirs. Morrison also wrote the first biography of Stephen Foster. Morrison's daughter Evelyn Foster Morneweck, wrote a biography about her uncle, Chronicles of Stephen Foster's Family.
