invented the baseball, and when?
The modern baseball is akin to its English predecessor, the Cricket ball - a small, hard, leather-covered ball with a
solid cork center used for playing Cricket. American baseball came out of the game of rounders', which used a soft ball. Rules
written in 1845 called for replacing rounders' soft ball with a smaller, hard ball.
The earliest baseballs were entirely handmade by players and local merchants. They featured a solid core wrapped in yarn
or string and covered in a single four-sided piece of leather, stitched together to form "x". Since baseball's invention in
1839, and throughout the 1850s and 1860s, many changes have been made to the ball's core, wrappings, casing, stitching, size,
and weight. In 1954, three New York baseball teams set the baseball's weight at up to 6 ounces, and its diameter up to 3-1/2
inches. The first baseball convention in 1957 decided upon a slightly larger baseball, one that would measure up to 10-1/4
inches in circumference, and weigh up to 6-1/4 ounces - a bit larger than today's 5-1/4-ounce baseball.
The first factory-made baseballs were produced by Harwood and Sons, in Mass., in 1858. The same company also made the
first baseballs covered by two pieces of leather stitched together to form a figure-eight design. The ball's core construction
continued to be improved on, and rules for that were created. A.G. Spalding patented the first cushioned wood core in the
late nineteenth century.
