Jul 11, 2019 · The first person to observe and discover the cell, Robert Hooke (1635-1703), did so using a crude compound microscope – invented near the end of the 16th century by Zacharias Janssen (1580-1638), a Dutch spectacle-maker, with help from his father – and an illumination system Hooke designed in his role as curator of experiments for the Royal Society of London.
From the 1830s, cells and cell theory became the focus of medical and biological research, thanks to the central role of the microscope in laboratory science. Researchers were able to describe the body at the microscopic level more consistently and with greater confidence in what they saw.
4.2 Summary. Cells are the basic units of structure and function in living things. They are the smallest units that can carry out the processes of life. In the 1600s, Hooke was the first to observe cells from an organism (cork). Soon after, microscopist van Leeuwenhoek observed many other living cells.

Among those were, in France, Félix Archimède Pouchet (1800–1872) and his theory of heterogenesis and Hermann Pidoux (1808–1882) and his theory of organic vitalism and, in the UK, Lionel Beale (1828–1906) .
Apr 26, 2023 · A few years later, in 1883, Charles Fritts actually produced the first solar cells made from selenium wafers – the reason some historians credit Fritts with the actual invention of solar cells. However, solar cells as we know them today are made with silicon, not selenium. Therefore, some consider the true invention of solar panels to be tied ...
The neuron doctrine is the concept that the nervous system is made up of discrete individual cells, a discovery due to decisive neuro-anatomical work of Santiago Ramón y Cajal and later presented by, among others, H. Waldeyer-Hartz. [1] The term neuron (spelled neurone in British English) was itself coined by Waldeyer as a way of identifying ...
