Unfortunately, “The History of Fishes" almost prevented another groundbreaking work from being published: Isaac Newton’s "Philosophiae Naturalis Principia Mathematica" ("Mathematical Principles of Natural Philosophy").

Fortunately for Newton (and for science), his “Principia” caught astronomer Edmond Halley’s eye. Halley would be remembered mainly for computing the orbit of the comet that bears his name, but at the time he was a young Royal Society clerk.
