"Hartmann lines" are named after him.
After leaving school Ernest Hartmann studied medicine in Mannheim and Jena. During World War II he worked as a staff physician and was in American captivity. After his return from captivity, he opened a medical practice in Eberbach on the river Neckar, where he stayed more than 40 years as a practitioner.
Besides his work as a doctor, in 1948, Ernest Hartmann still occupied himself, together with his brother Robert, with geobiology and dowsing. Furthermore, he occupied himself with homeopathy and later also biology. The Research Group for Geobiology (Dr. Hartmann e.V.), a registered association, was founded by him.
