Who found the first crystal?

The first known crystals were likely discovered by ancient civilizations, such as the Egyptians and Mesopotamians, who utilized natural crystals like quartz for various purposes. However, the systematic study of crystals began in the 17th century with scientists like Johannes Kepler and later, Robert Hooke. The term "crystal" itself comes from the Greek Word "kristallos," meaning "frozen," which reflects the early belief that crystals were forms of ice. Thus, while no single person can be credited with "finding" the first crystal, many contributed to the understanding and study of crystals throughout history.
