- Year of Death: 1867
- Experiment: Installation Of His Rotary Printing Press
- Cause of Death: Gangrene
William Bullock was yet another brilliant man who was a key figure during the mid-1800s. The American inventor helped to revolutionize the printing press of the time, leading to advancements that helped to increase speed and efficiency. Bullock invented the web rotary press, which was an improvement on the rotary printing press Richard March Hoe invented beforehand. In fact, it is Bullock’s concept that would go on to be used in most printing presses. He filed a patent for it in 1863, where it was explained that his press used a continuous web or roll of paper.
It would be the first machine for curved stereotype plates. It also printed both sides of the sheet and cut either before or after printings. Of course, this would join the killer scientific experiments list when Bullock attempted to install and test his machine in Philadelphia in 1867. Some part of it fell on Bullock’s foot, crushing it. Sadly, this led to the foot developing gangrene and needing to be amputated. However, this was not done in time and resulted in the gangrene killing him during the attempted amputation.
