Sculptor and teacher, born in Halifax, where she continued to live. She entered Leeds School of Art in 1920 to train as a sculptor, with Henry Moore and Barbara Hepworth as fellow students. During the 1920s Miss Horner began a series of children portraits and animal studies and during World War II became a home teacher for the blind. After 1945 she returned to Leeds as a student and in the early 1950s became a part-time teacher of modelling and wood-carving at the Percival Whitley College, Halifax, also teaching at Halifax Art College. Her later work came increasingly under the influence of Jacob Epstein, and the 1960s saw her sculptures exhibited locally and nationally. Horner won the Leeds Gold Medal under the annual award for work by artists born of Yorkshire parents.
