Some of Leeuwenhoek’s simple microscopes could magnify objects more than 250 times, but Hooke’s compound microscopes only magnified somewhere between 20 and 50 times. Leeuwenhoek’s instruments were more powerful, so why did Hooke not use one? He knew how to make and use a simple lens, but he chose not to.

Aquatic microscope made by John Cuff of London, around 1750. National Museum of American History, cat. MG*M-09898. At a meeting of the Royal Society in the winter of 1738-1739, Cuff met Johann Nathanael Lieberkühn, a German physician who had come to England to promote two instruments he had recently devised.
Who invented the microscope in 1666?
Antoni Van Leeuwenhoek (1635-1723) was a Dutch tradesman who became interested in microscopy while on a visit to London in 1666. Returning home, he began making simple microscopes of the sort that Robert Hooke had described in his, Micrographia, and using them to discover objects invisible to the naked eye.
Where is Galileo’s microscope?
The image on the left and the diagram on the right come from a terrific online exhibit about Galileo’s microscopes, the Museo Galileo in Florence.
How was the first simple microscope made?
The history of the microscope spans centuries. Roman philosophers mentioned “burning glasses” in their writings but the first primitive microscope was not made until the late 1300’s. Two lenses were placed at opposite ends of a tube. This simple magnifying tube gave birth to the modern microscope.
What is simple optical microscope?
Simple optical microscope
A simple microscope is a microscope that uses only one lens for magnification, and is the original light microscope. Van Leeuwenhoek’s microscopes consisted of a small, single convex lens mounted on a plate, with a mechanism to hold the sample or specimen to be examined.
What did Hooke create?
What did Hooke contribute science?
English physicist Robert Hooke is known for his discovery of the law of elasticity (Hooke’s law), for his first use of the word cell in the sense of a basic unit of organisms (describing the microscopic cavities in cork), and for his studies of microscopic fossils, which made him an early proponent of a theory of …

Hooke published, under the title Micrographia, the results of his microscopic observations on several plant tissues. He is remembered as the coiner of the word “cell,” referring to the cavities he observed in thin slices of cork; his observation that living cells contain sap and other materials too often has…
How did Robert Hooke’s microscope advanced cell theory?
The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory.
