Rosemarie Adcock was born weeks after her family immigrated to the United States from Germany and Austria through Canada. In addition to theological study at Westminster and Gordon Conwell Seminaries, she studied at the American Academy of Art in Chicago (1978-80) under Eugene Hall, an apprentice of the Russian painter, Alexander Zlatoff-Mirsky, who was himself an apprentice to the Russian master, Ilya Repin. She also studied at the School of the Art Institute of Chicago (BFA 1987). She received a stipend from the Minister of Culture of Baden-Wurtenberg, Germany, and studied printmaking and monumental painting at the Staatliche Akademie der Bildenden Künste Karlsruhe (1986-88) under the director Klaus Arnold, and also Max Neumann, guest professor for the class of Markus Lupertz.
Rosemarie is a published author and international conference speaker. Her paintings are in numerous private and corporate collections in the United States and Western and Eastern Europe. She has exhibited extensively in the United States and Europe, winning multiple awards. Notable exhibitions include shows at Princeton Theological Seminary, the Museum for Florida Women Artists and twice at the Museum of Florida Art where her work received awards on both occasions. She was awarded two consecutive years of First Place awards at the Illinois State Fair Professional Artist Exhibitions.
Her earlier exhibition of over 120 paintings of Russian peasants toured in the United States and Western Europe for over 7 years. After the resulting acquisition of humanitarian relief assistance of over $1.25 million in gift-in-kind donations for orphans and impoverished Russian families, the artist founded the charitable organization, Arts for Relief and Missions in 1993.
