John Joseph Merlin (1735-1803) was a Dutch inventor. He learned his trade as a mathematical instrument maker in Paris. Merlin moved to England in 1760. He founded his mathematical instrument-making business in 1773. Merlin invented this weighing machine. He also set up “Merlin’s Mechanical Museum”. This featured instruments such as weighing machines, clocks and even a device allowing blind people to play cards. His museum was popular in London as a place of amusement and instruction. Merlin, something of an entrepreneur, is also believed to have popularised roller skates.
