"Revere" is too strong a word, but for writers I would list Samuel Beckett, Vladimir Nabokov, Thomas Pynchon, TS Eliot, Robert Frost, and for his one most transcendent poem, the WWI poet Wilfred Owen. It was a brutal task editing this particular list down.
For music it would be Robert Zimmerman and Tom Waits.
In the realm of American politics, I admire the deep personal courage of Jeanette Rankin and Edmund Ross. And I am deeply grateful to Abraham Lincoln, who helped preserve the United States of America.
Internationally, Nelson Mandela comes as close to a man with a near spotless record of impeccable courage as I can imagine.
