The purpose of this presentation is to acknowledge the pioneering work
of a key historical figure who contributed to the available knowledge
in anatomy and biomechanics, developed political and social infrastru
cture to promote the maturation and standardization of chiropractic ed
ucation, and influenced a paradigmatic shift away from a monocausal be
lief in the origin of disease. Literature search and archives retrieva
l were used. Janse was a man with personal intellectual integrity and
whose personal commitment was driven by a family experience. Evidence
shows that Janse took bold initiatives to influence the chiropractic p
rofession and give it the opportunity to develop as a legitimate healt
hcare discipline. Janse was a visionary clinical scientist and educato
r whose 38-year tenure as president of a chiropractic college enabled
him to influence the course and development of his profession.
