The Raw Apples That Started a Diet Revolution
A doctor born in Aarau would later treat his own jaundice with nothing but raw apples, then spend his career trying to convince medicine that food alone could heal.

The facts
- Born
- August 22, 1867, in Aarau, Switzerland

- Education

Maximilian Oskar Bircher-Benner was born on August 22, 1867, in Aarau, Switzerland, to Heinrich Bircher and Berta Krüsi. He studied medicine at the University of Zurich and then opened his own general clinic. During the clinic's first year he came down with jaundice, and he said it was raw apples that brought him back. That recovery pushed him toward an idea most of his peers found cranky: treating patients with raw fruit, oats, and nuts instead of drugs. He later ran a sanatorium on Zurich's Zürichberg called Lebendige Kraft, or Living Force, where the apple-oat dish he built around his own recovery would eventually travel the world as muesli.

Why it still matters
Raw-food vegetarianism and the modern health-food movement both trace back to one doctor's stubborn bet that an apple could do more for him than the medicine of his day.
