Hewson, another globulist, confirmed in 1771 van Leeuwenhoek’s finding of globules in the blood, and that they swelled and shrank in different solutions — one of the earliest experiments in cell biology. In describing the contents of the lymphatic gland, Hewson refers to “an almost infinite number of small cells”.

Jul 27, 2023 · Cell Theory in Timeline. Cell discovery began in the 1600s when a Dutch shopkeeper, Antony van Leeuwenhoek, discovered simple lenses and used them to visualize single-celled organisms, which he collectively termed ‘animalcules.’. The discovery of a compound optical microscope by Hans and Zacharias Janssen in 1590 made it even easier to ...
Jul 30, 2022 · A cell is the smallest unit of life. Most cells are so tiny that they cannot be seen with the naked eye. Therefore, scientists use microscopes to study cells. The first microscopes were used in the 1600s by Antony van Leeuwenhoek, a Dutch shopkeeper who had great skill in crafting lenses.
In a long series of papers van Leeuwenhoek then described many specific forms of these microorganisms (which he called "animalcules"), including protozoa and other unicellular organisms 3, 4, 5.

In 1675, using a simple but powerful microscope of his own making, Leeuwenhoek was able to observe single-celled organisms, which he described as “animalcules” or “wee little beasties,” swimming in a drop of rain water. From his drawings of these little organisms, we now know he was looking at bacteria and protists.
Soon after Robert Hooke discovered cells in cork, Anton van Leeuwenhoek in Holland made other important discoveries using a microscope. Leeuwenhoek made his own microscope lenses, and he was so good at it that his microscope was more powerful than other
