Clara Sophia Jessup Bloomfield-Moore (1824–1899) was an American philanthropist, writer, and philosopher who became a prominent figure in late nineteenth-century literary and social circles. Writing under her own name as well as the pseudonym Mrs. Clara Moreton, she published novels, poetry, and widely read guides on social etiquette. Her literary contributions reflected the shifting social dynamics of Victorian-era America, offering insight into the domestic and moral expectations of the period.
Beyond her creative writing, Moore was deeply engaged in intellectual and philosophical pursuits. She is particularly remembered for her significant financial and intellectual patronage of John Ernst Worrell Keely, an inventor who claimed to have discovered a new source of physical energy based on sympathetic vibratory physics. Moore wrote extensively in defense of Keely's theories, publishing Keely and His Discoveries in 1893 to advocate for his controversial scientific claims.
Throughout her life, Moore also dedicated herself to philanthropic endeavors. During the American Civil War, she was active in relief efforts, helping to establish the Special Relief Committee in Philadelphia. Her later years were spent largely in Europe, where she continued her writing and philosophical inquiries until her death in 1899.
