This dulcimer was previously owned by Anne Grimes (1912-2004) an American journalist, musician, and historian of American (particularly Midwestern) folklore. Grimes studied voice and piano at Ohio Wesleyan and initiated graduate studies at Ohio State University. Following her education, Grimes was a music teacher, music and dance critic, and radio host. After WWII, Grimes began collecting and documenting folk songs throughout Ohio, as well as collecting Appalachian dulcimers and zithers. She would continue this work, performing, recording, and lecturing on instruments from her collection throughout the rest of her career.
