Lavinia C. Winzenburg (b. Hartt) (1847-1915) was born in Boonville, Missouri, and died in Houston, Texas. By 1850 she had moved with her family to Elizabethtown, Virginia, and by 1860 to Covington, Indiana. In the late 1860s she attended Wesleyan Female College in Cincinnati, Ohio, and subsequently became a music teacher. She married Adolph J. Winzenburg, a bookmaker and later a cigarmaker. By 1880 they had moved to Joplin, Missouri, and by 1887 to Denver, Colorado. Sometime after her husband's death in 1896, Winzenburg moved to Houston to live with a niece. In 1886 Winzenburg wrote to Mary Baker Eddy from Olney, Illinois, to order a copy of Science and Health with Key to the Scriptures.
