Painless Parker's legacy: ethics, commerce, and advertising in the professions
1University of the Pacific, School of Dentistry, San Francisco, CA, USA.
Abstract:
This presentation will review the life and contributions of Dr. Edgar Parker, the infamous and controversial pioneer who specialized in a precarious straddling of the ethics of the commercial marketplace and the ethics of care. Something of a Rorschach test, he was alternatively referred to as a charlatan, the first people's dentist, a renegade, a crusader, a quack, the Henry Ford of dentistry, and "a menace to the dignity of the profession". He eventually owned and managed thirty dental offices, several in San Francisco, as well as the Parker Dental Circus. Because many young, twenty-first century practitioners have little problem with slick advertising, it seems appropriate to revisit Painless Parker's career and contribution to the current state of affairs.
