He was an ancient greek philosopher.Democritus expanded the atomic theory of Leucippus. His theory was matter could not be divided into smaller and smaller pieces forever, eventually the smallest possible piece would be obtained. This piece would be indivisible. He named the smallest piece of matter “atomos,” meaning “not to be cut.”

He was the first to describe how blood was pumped throughout the body with the heart. Harvey was also the first to suggest that humans and other mammals reproduced via the fertilisation of an egg by sperm.
-
He came up with three scientific laws describing orbital motion, originally formulated to describe the motion of planets around the Sun.
-
He came up with his own atomic theory. Three principles remain unchanged.
-
He is famous for constructing a periodic table of the elements similar to the one used today.
-
He was the principal founder of the theory of chemical structure.
-
He implemented the classical chemical methods into organic chemistry.
-
He is known for his principles of vaccination, microbial fermentation, and pasteurization.
-
They were known for their studies about radioactivity.This helped them uncover the elements radium and polonium.
-
He came up of the orbital theory of the atom. he used his foil experiment to help him.
-
He is most remembered for advancing the theory of continental drift.
-
He came up with his own model of the atomic structure, which became the basis of the famous quantum theory.
-
He showed that cathode rays were made up of negatively charged particles, which were unknown at the time. It then led to the discovey of the electron. Joseph was also recognized for finding the first evidence for isotopes of a stable element.

He is known for formulating the theory of a double-helix structure for DNA.He is the co-discoverer.
-
The model of atomic structure, where electrons do not follow fixed orbits,but tend to occur in certain areas around the nucleus at any given time.

Aristotle did not believe Demcritus's theory, so the people did not believe him either.
