Invention: The web rotary press Country: United States Died: 1867 A New York inventor, William Bullock's improvements to the rotary printing press proved to be a huge boon to the industry with its increased efficiency compared to previous iterations. Bullock's invention was by no means the product of a mad scientist, and its influence can still be felt today. Bullock's improvements included removing the need for the hand-feeding of paper and an extremely sharp knife that was able to cut off sheets with high precision. At the culmination of Bullock's involvement, the press was able to print 30,000 sheets per hour. While making some adjustments to his machine, Bullock attempted to kick a belt onto one of the pulleys. However, his leg got caught in the machinery, and was crushed. It developed gangrene, and Bullock died during an amputation operation.
