The therapeutic benefits of cold water treatments have been in the news and social media lately. One 19th century practitioner was Dr. Mary Olney Brown, pictured here. Dr. Brown was affectionately called “Coldwater Brown,” to distinguish her from another Olympia woman with the same last name, known as “Presbyterian Brown.” Dr. Brown is better remembered today for her ardent promotion of universal suffrage.
