Elizabeth van Raders of France is listed as a student in the 1906 Science of Chiropractic. It’s not recorded if Dr. van Raders ever practiced in France. There’s some evidence that Gaston Gross of France started calling himself a chiropractor in 1919. In 1921, he made it official by attending the Palmer School.
