Dr. Pierce's Medical Discovery Barn, Sonoma County, California
"Dr. Ray Vaughn Pierce (1840-1914) was a 19th and early 20th century pharmacist that was famous for numerous self-concocted medications that he invented. His medicines were marketed to cure female ailments, digestive illness, cancer, fatigue, headache, tumors, menstruation and many more. Dr. Pierce earned a substantial amount of income via mail-order prescriptions. Arguably more entrepreneur than part of the mainstream medical community, Dr. Pierce no doubt left a remarkable legacy that lives on today via numerous old barn advertisements across the country."
