Who invented the coffee grinder?

The first coffee grinder was invented in the 16th century by the Ottoman Turks. The original grinder was a mortar and pestle, which was used to grind the coffee beans into a fine powder. The mortar and pestle was later replaced by a hand-cranked grinder, which was more efficient and easier to use. In the 19th century, electric coffee grinders were invented, which made the process of grinding coffee beans even easier and more convenient.
