Daniel David Palmer (1845-1913)
Raised in Port Perry, D.D. Palmer was self-educated, well read and keenly interested in spiritualism and alternative medicine. While working as a magnetic healer in the United States, his clinical observations and analysis led him to conclude that proper spinal alignment could restore 'nerve flow' and ensure good general health. Despite legal and financial setbacks, he published books on chiropractic treatment and founded and taught at several chiropractic schools. Palmer is recognized as the founder of chiropractic for his crucial role in creating and popularizing this alternative medical care in North America.
