Born Stella Elmendorf in San Antonio, Texas on December 17, 1885, she studied with Robert Henri at the Art Students League in New York City in 1910-1911. She took part in the Armory Show of 1910. She added the initial T. as a middle name at that time, as she was known by her fellow art students as "Texas".
She married Dr. W. Russell Tylor in Madison, Wisconsin in September, 1919. They had one daughter, born May 2, 1925 in Chicago. From 1927 on until her husband's death in 1945, she lived and worked in Urbana-Champaign, Illinois. Thereafter, she returned to her hometown of San Antonio, Texas, where she continued to be active until about 1975.
She won numerous awards over her long career, including, among others, first prize at All Illinois Society of Fine Arts, Chicago and purchase prize at the Witte Museum, San Antonio, and was exhibited in New York City, San Francisco, Wilmington, Austin, and San Antonio, Texas.
Mrs. Tylor passed away in New Braunfels, Texas, on December 27, 1980.
