Hans and Zacharias Janssen

1590

They were known for inventing the compound optical microscope. It made it easier and more efficient to observe cells. It helped many people learn more about cells

Marcello Malpigihi

1660

He was one of the first to use a microscope for the research of cells. He studied the organs of animals. He found the function of many organelles.

Robert Hooke

1665

Hooke designed a microscope. He observed a piece of cork and looked at its structure. He came up with the "cell". He worked on engineering the microscope.

Anton Van Leeuwenhoek

1674

He made improved lenses for microscopes. He studied animals with a single cell. He learned about bacteria.

Francesco Redi

1748

Redi wanted to prove an idea wrong. Many people believed that maggots came from meat. Francesco set up experiments to show that cells can only be made from other cells. This was an important idea in the cell theory.

Matthais Schleiden

1833

He recognized the importance of the nucleus. He was a German botanist and was the co-founder of the cell theory. He also studied cell division.

Theodore Schwann

1838

Theodore and Matthais came up with a conclusion. They were both botanists and studied plants. Plants are made up of one cell. The cell is the building block of all plants.

Rudolph Virchow

1855

Virchow was known for many discoveries. He was very important to the cell theory. He studied diseases and how they affect organisms. He also learned about tissue.

Gregor Mendel

Approx. 1856

Mendel discovered recessive and inherited traits. He did his experiments on pea plants. He found the differences between recessive and inherited traits.

Robert Brown

1858

Brown was an English botanist. He worked with Matthias Schleiden. Robert browm discovered something very important. He found the nucleus and what it does.

Walter Fleming

1879

Fleming was a pioneer of cytogenetics. He studied the nucleus under a microscope. He did his studied on mitosis.

Thomas Hunt Morgan

1907

Morgan was known for his experiments on fruit flys. He studied genetics. He was a zoologist.

Francis Crick and James Watson

1962

In 1962 Crick arms Watson won a Nobel prize for their work. They studied DNA and published their discoveries. They learned about genetics.
