Who invented the baseball cap?

The short answer is no one knows, or likely even cares. The long answer is the first drawing of a man in a straw hat was discovered in an Egyptian tomb dated to 1300BC.

Since we are living in 2019, a better question might be where did the modern baseball/golf cap come from? Well, in 1860 an amateur baseball team the Brooklyn Excelsiors wore caps that resemble modern baseball hats. Their version featured a rounded top design and long visor with the telltale button on top.

Over time, the design of baseball hats has been improved to provide greater utility, comfort, and appearance. By 1954 New Era was producing colorful and comfortable hats for professional baseball teams. Soon thereafter, decorators began producing embroidered hats for uniforms and as promotional items, although the embroidery machines of the time were very crude.”
