Ludolph Christian Treviranus and Johann Jacob Paul Moldenhawer are credited for the formulation of Cell theory.

Based on the timeline of the cell theory, father and son, Hans and Zacharias Janssen started produced the first compound microscope. They combined two convex lenses within a tube. This was in the year 1595.
The Cell Theory is a basic principle of Biology. The cell itself was first discovered by Dr. Robert Hooke in the mid-1600s. During the early and mid parts of the 1800s, German scientists Schwann and Schleiden, and German physicians Virchow and Remak established that "1- cells were the basic unity of life; 2- all living organisms are made of cells; 3- cells develop from pre-existing cells". That is the theory. Why is it called a "theory"? Good question! - it is no more a theory than that of relativity, natural selection and evolution, etc. Note that the four gentlemen I mentioned earlier sometimes worked together, sometimes plagiarized each other . . .
Robert Hooke discovered cells. He took microscopy as a hobby and used to view various specimen under his microscope. Once, he made a thin slice of cork and observed it under the microscope. Since corks are made from the oak trees, they were made up of cells. Hooke observed numerous tiny compartments and called them "cells".
Theodor Schwann wrote the first two parts of the cell theory
The cell theory was introduced by two biologists, Schleidan and Schwann
Two scientists came up with The Cell Theory. It was in 1839, Matthias Schleidan and Theodor Schwann, two German Biologists came up with this theory.
Schleiden and Schwann
Credit for developing cell theory is usually given to three scientists: Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow. In 1839, Schwann and Schleiden suggested that cells were the basic unit of life. Their theory accepted the first two tenets of modern cell theory. However, the cell theory of Schleiden differed from modern cell theory in that it proposed a method of spontaneous crystallization that he called "free cell formation".
The special body of a cell, known as the nucleus, was discovered by two scientists: Franz Bauer in 1804 and Robert Brown in 1831.
Cerium was discovered in two different places. It was discovered in Sweden by two people and then in Germany by a chemist, both in 1803.
coal was discovered by two people digging and then they found coal so then they invented coal and discovered it
Anthracite coal was discovered through surface outcroppings and natural erosion exposing the coal seams. Native Americans used anthracite for fuel before European settlers arrived in North America. In the early 19th century, it became an important source of fuel for heating and industry.
Well I'll just use two points from the cell theory: 1) The cell is the basic unit of structure and function in all living things. In the late 1800s, a scientist named Schwann told the world that he observed cells in animals. A short time later, another scientist named Schleiden said the same for plants. This was a huge start to the cell theory. 2) All cells rise from pre-existing cells. It's hard to believe but at one point actual scientists believed that living things could come from inorganic matter. It was not until Louis Pasteur's experiment with the S-shaped flask, and the boiled water, that people started to shun the thought of spontaneous generation and look at this final addition to the cell theory.
