Lemuel Gulliver

He supposedly studied for three years (c. 1675–1678) at Emmanuel College, Cambridge, leaving to become an apprentice to an eminent London surgeon; after four years (c. 1678–1682), he left to study at the University of Leiden, a prominent Dutch university and medical school.

In Brobdingnag, he compares a loud sound to the Niagara Falls, so presumably, he visited the place at some point.

Between his travels, he married Miss Mary Burton (c. 1688), daughter of a London hosier.

The earliest editions of the book credited Gulliver as the author, whom many at the time believed to be a real person.

On Mars's largest moon, Phobos, the crater Gulliver is named after him, while the crater Grildrig has the name given to Gulliver by the farmer's daughter Glumdalclitch in Brobdingnag, because of Swift's 'prediction' of the two then undiscovered Martian moons, which his Laputan astronomers had discovered.
