How does the author make it clear that Dr. Benjamin Rush was a dedicated
physician?

here's my answer

Explanation: During the spring of 1813, former presidents John Adams and Thomas Jefferson were united in grief at the death of a mutual friend who had recently persuaded them to forget their bitter rivalries. Like the two celebrated statesmen, the eminent physician and social reformer Benjamin Rush had been a Founding Father, one of 56 men who signed the Declaration of Independence in 1776.

But Adams and Jefferson believed that Rush deserved to be remembered for much more than his conspicuous enthusiasm for the cause of American liberty. Jefferson wrote that “a better man, than Rush, could not have left us,” extolling his benevolence, learning, genius and honesty. Adams replied with equal praise: He knew of no one, “living or dead,” who had “done more real good in America.” Writing to Rush’s son, Richard, Adams maintained that as a “benefactor” to his country, the doctor deserved greater recognition than even the celebrated polymath Benjamin Franklin.
