Gosh, I actually read through both my comments, s I could not recall writing about him

John Galt is a character in Ayn Rand's novel Atlas Shrugged (1957). Although he is not identified by name until the last third of the novel, he is the object of its often-repeated question "Who is John Galt?" and of the quest to discover the answer.

As the plot unfolds, Galt is acknowledged to be a philosopher and inventor; he believes in the power and glory of the human mind, and the right of the individual to use their mind solely for themselves.
