Who invented chemistry ?

Chemistry is an ancient pursuit. At this point no one
person can be named as the inventor or discoverer of chemistry, but we can name some
specific landmark discoveries to get a sense of how long chemistry has been important to
humankind. One could make a case for chemistry as a practical art dating back to the
pigment formulation for cave paintings from 35,000 years
ago.


During the reign of Hammurabi in ancient Babylon,
around 1700 BCE, the known metals were being studied, and their properties were being
linked by astronomers to the heavenly bodies. This is the oldest example of formal
theoretical chemistry that we know of.


Almost 1300 years
later, in 430 BCE, the Greek philosopher Democritus put forth his theory that all matter
is made of tiny particles called atoms.
