What historical figure is known for hiring the first "doctor's assistant" which led to the formation of the PA role?

Amos N. Johnson is recognized for hiring the first person who would be considered a "doctor's assistant," thus laying the groundwork for the development of the Physician Assistant (PA) role. In the 1940s, Johnson, a general practitioner, employed a trained nurse named "Buddy" Treadwell to extend his practice, which involved both clinical duties and patient care. This innovative model demonstrated the need for healthcare providers who could enhance the efficiency of medical practice, ultimately leading to the establishment of structured PA programs in the subsequent decades. The role that Treadwell filled was integral in shaping the concept of a physician extender, highlighting the significance of collaboration in healthcare.

While Dr. Stead contributed significantly to the creation of the PA profession and Thelma Ingles was an advocate for advanced practice nursing, and Henry Treadwell was involved in the PA program development, it was Amos N. Johnson who directly initiated the practice of hiring individuals to assist physicians in the way that ultimately informed the PA model as we know it today.
