The golf ball with rubber at its heart
Coburn Haskell and Bertram Work helped change golf by winding stretched rubber thread inside a ball. Their late-nineteenth-century design put an elastic core beneath a tough cover. The outside looked familiar; the response to a strike did not.
Why winding the inside changed the game

The patent filed in 1898 and granted in April 1899 described tightly wound elastic thread under a gutta-percha shell. The important innovation was the construction inside the ball, not a new pattern added to its surface.
A wound core could respond to impact differently from the earlier solid gutta-percha ball. As the design was refined and adopted, extra distance changed what golfers could reach and what established courses had to accommodate. The construction influenced ball-making for decades.
The period illustration makes the hidden idea visible: much of the engineering was packed into a small interior rather than advertised on the outside. Haskell’s story is often compressed into a lucky experiment with rubber. The more useful lesson is the partnership and refinement that turned a promising material into a playable product.
