Adelia Sarah Gates

She was born in the Susquehanna Valley.[5] Gates worked as a governess, farmworker, teacher, and as a factory worker in the Lowell Mills before attending college.[6] In her thirties, she attended Antioch College, only to leave after two years due to health issues.[7]

She started painting in her fifties, after taking lessons from Emilie Vouga in Geneva.[5][8] Later in her life in San Francisco, she sought out further education in identification and naming of specimens from noted botanists Sara Plummer Lemmon and John Gill Lemmon, for which she traded lessons in "flower painting" and sketching.[9]

During her lifetime, a colorful biography of her life and travels including expeditions to paint specimens was written by Adela Elizabeth Orpen. Titled The chronicles of the Sid, or, The life and travels of Adelia Gates, it was published in New York by Fleming H. Revell Company[10] and in London by the Religious Tract Society.[11] In the book, Orpen describes Gates, who was her governess for 14 years, by saying that "Though an artist, she is not a great genius; though a traveller in many lands, she has had no thrilling adventures. She never did any horrid deed, nor suffered any hideous privations."[7] Orpen refers to Gates as "the Sid," rather than Adelia, throughout the book explaining that "Sid means lady or mistress, and is the title by which she was known in the Sahara."[7]

Gates died in San Francisco on September 21, 1912.[12] After her death, over 600 of her works were exhibited and donated to the United States National Museum, which later became the Smithsonian Institution.[13]
