Wrong again. The ORIGINAL anesthesia providers in the USA was a Doctor (Crawford Long, 1842) and a Dentist (Horace Wells, 1845). In England, where they had enough doctors, doctors became the anaesthetists. In the USA out east, where they had enough physicians in an area, it was physicians who were the first anesthesia providers.
However, later in the USA, where we had wide open spaces and not enough doctors, the job "fell" to the nurses.
And that was not until the "late 1800s" according to the AANA website. (Going to argue with your own Association?) The earliest record of a NURSE giving anesthesia was 1877 in Pennsylvania. (Also from the AANA website.)
That was 30 years into anesthesia development so nurses were hardly "the original anesthesia provider."
