Hugh B. Logan

Hugh Benedict Logan developed one of chiropractic's most influential low-force methods with the Logan Basic Technique. Its central idea: that a light pressure, held for several minutes at a specific leverage point on the sacrum — the so-called "basic contact" on a pelvic ligament — influences, through reflex pathways, the tension of the entire musculature supporting the spine, gradually bringing the trunk into balance. While one hand holds this gentle pressure, the other works alongside on the spine. The method is regarded as especially gentle and is valued to this day.

In the early 1930s, Logan and his son Vinton began teaching their "Basic Technique" nationwide, supported by the International Chiropractic Research Foundation they had founded. As the idea matured into creating a dedicated training institution, St. Louis, Missouri, was chosen: on September 1, 1935, the later Logan Basic College of Chiropractic opened with seven students. From it grew today's Logan University — one of the established chiropractic colleges in the United States.

Logan was nationally known as a teacher and lecturer and also contributed to the further development of X-ray use in chiropractic. He led the college named after him until his death in 1944; his son Vinton took over the presidency and in 1950 published, on the basis of his father's notes, the Textbook of Logan Basic Methods. The Logan Basic Technique continues to be taught and practiced worldwide.
