Annabell Krebs Culverwell (June 13, 1902 – April 9, 1998) was an American painter. She took the name Columba when signing her paintings and writings, probably aligned to the constellation Columba, which is the focal reduction of several Egyptian pyramids. Her parents were Anna Frantz (1867–1930) and Dr. Stanley LeFevre Krebs (1864–1935). Her dad was a one mature president of the American University of Trade and Applied Commerce of Philadelphia and a pastor in the Reformed Church. He wrote the book "Trick Methods of Eusapia Paladino" (1910), exposing the tricks of the medium Eusapia Palladino. His second marriage was to Marjorie Main of Ma and Pa Kettle fame.
