At age eighteen DeNeale entered the School of Design in San Francisco and studied there for eight years under Arthur Mathews. Next she took private lessons from William Keith, her most influential teacher. In 1903 Morgan fell in love with Carmel and became a regular summer fixture, working in watercolors and pastels, before purchasing a permanent home there in 1910. Morgan was soon regarded as the “devoted, moving spirit of the art life of Carmel.” Her attendance at the Chase Summer School of Art in 1914 marked her change in medium to gouache as well as her departure from the Tonalist aesthetic to the more open brushwork and vibrant colors of the Impressionists. Great success accompanied her move to large-scale oils. Wrote one critic, “The almost masculine vigor that Morgan’s works display requires space. Resounding color is spread with a broad, vigorous touch…She has done what few women in the field have achieved. She has made her livelihood with her art.” When she died of heart failure in 1948, her honorary pallbearers included CAA luminaries Ferdinand Burgdorff, Arthur Hill Gilbert, Armin Hansen, Laura Maxwell, Frank Myers, Myron Oliver, John O’Shea, William Ritschel, George Seideneck, and William Watts.
