"A plague doctor was a special medical physician who treated those who had the plague. They were specifically hired by towns that had many plague victims in times of plague epidemics. Since the city was paying their salary, they treated everyone: both the rich and the poor. However, some plague doctors were known for charging patients and their families extra for special treatments and/or false cures. They were not normally professionally trained experienced physicians or surgeons, and often were second-rate doctors not able to otherwise run a successful medical business or young physicians trying to establish themselves."
