William Ernest Henley was a good friend of Robert Louis Stevenson, and the physical and personality model for Long John Silver. His daughter Margaret (who died at the age of 5) gave the world the name "Wendy" when she referred to her father's friend J.M. Barrie as "fwendy-wendy".
And then there is the poem:
Out of the night that covers me,
Black as the Pit from pole to pole,
I thank whatever gods may be
For my unconquerable soul.
In the fell clutch of circumstance
I have not winced nor cried aloud.
Under the bludgeonings of chance
My head is bloody, but unbowed.
Beyond this place of wrath and tears
Looms but the Horror of the shade,
And yet the menace of the years
Finds, and shall find, me unafraid.
It matters not how strait the gate,
How charged with punishments the scroll,
I am the master of my fate:
I am the captain of my soul.
