After Voelcker's death in 1930, the house became the home of his daughter, Theresa Voelker (later generations spelled the name without the 'c') and her husband, Dr. Rudolph Orth.[3] Their daughter, Elisabetha Orth, who lived in the house most of her life, established the organization which now runs the museum in her will.[4] When the Museum was incorporated, extensive restoration of the property was undertaken prior to opening in 2003.
