Robert Hooke: One Who Discovered Cells


Robert Hooke (1635-1703) was an English natural philosopher and polymath whose contributions to science and engineering were instrumental in shaping the world we live in today. Hooke is perhaps best known for his law of elasticity, but his work spanned a wide range of fields, including astronomy, microscopy, architecture, and geology.

Early Life and Education

Robert Hooke was born on July 18, 1635, in Freshwater on the Isle of Wight, England. His father, John Hooke, was a clergyman who served as the curate of All Saints' Church, Freshwater. Robert was the youngest of four children, and his mother died when he was only three years old.

Despite his humble beginnings, Hooke showed an early aptitude for learning and was sent to London to study at Westminster School when he was thirteen. There, he excelled in mathematics and Latin and became known for his talent in drawing and sketching.

In 1653, Hooke enrolled at Christ Church, Oxford, where he studied natural philosophy under the tutelage of Robert Boyle. During his time at Oxford, Hooke became Boyle's assistant and worked on many of the experiments that would later form the basis of Boyle's famous law of gases.

Scientific Contributions

After leaving Oxford, Hooke took up a position as curator of experiments at the newly established Royal Society in London. There, he conducted a wide range of experiments and made many important discoveries.

One of Hooke's most significant contributions to science was his law of elasticity, which states that the extension of a spring is proportional to the force applied to it. This law is known as Hooke's Law and is still widely used today in engineering and materials science.

Hooke was also a skilled microscopist and was the first person to observe and describe the microscopic structure of many everyday objects, including feathers, hair, and cork. He published his observations in his book "Micrographia," which was a groundbreaking work that helped establish the field of microscopy. He observed tiny, empty spaces that reminded him of the small rooms or "cells" in a monastery, and he used the term "cell" to describe them.

Hooke's observations of cork cells were the first recorded observations of cells, and his work paved the way for further research on the structure and function of cells.

In addition to his work in physics and microscopy, Hooke made important contributions to astronomy, architecture, and geology. He designed several instruments for the Royal Society, including a pendulum clock and a microscope, and worked on the design of the Royal Observatory in Greenwich.

  • Hooke was a prolific inventor and designed a wide range of machines and instruments, including a hygrometer for measuring humidity, a balance spring for improving timekeeping in watches, and a spring-driven car for the Royal Society's experiments.

  • In addition to his work in microscopy, Hooke made important contributions to the field of optics. He was the first person to propose that light travels in waves, and he conducted experiments on the properties of light that helped pave the way for the development of the modern theory of optics.

  • Hooke was also an accomplished architect and helped rebuild many of the buildings in London after the Great Fire of 1666. He worked on the design of several churches, including St. Mary Magdalene in Paddington and St. Clement Danes in the Strand.

  • Hooke was a prolific writer and published many books and papers on a wide range of topics. In addition to "Micrographia," his most famous works include "Lectures and Collections of Monsieur Chr. Wren" (1665), "An Attempt to Prove the Motion of the Earth" (1674), and "The Posthumous Works of Robert Hooke" (1705).

  • Hooke's relationship with Isaac Newton was contentious, and the two men had several disputes over scientific ideas and priority. One of the most famous of these was the debate over the nature of gravity, which led to the publication of Newton's "Principia Mathematica" in 1687.

  • Despite his contributions to science, Hooke was not always appreciated in his own time. He was known for his prickly personality and was often involved in disputes with his colleagues. He also suffered from poor health in his later years, which limited his ability to work on scientific projects.

Later Life and Legacy

In later life, Hooke became embroiled in several controversies with other scientists, including Isaac Newton. Hooke claimed that Newton had stolen his ideas on the nature of light and accused him of plagiarism, but these claims were never proven.

Despite these disputes, Hooke remained a respected member of the scientific community until his death in 1703. He was buried in St. Helen's Church in Bishopsgate, London, but his grave was destroyed during the Great Fire of London in 1666.


Today, Hooke is remembered as one of the most important scientists of the 17th century and a pioneer in many fields of Science and Engineering. His work helped establish the foundations of modern physics and biology, and his legacy continues to inspire scientists and engineers around the world.


Q1. Who was Robert Hooke and what is he known for?

Ans. Robert Hooke was an English scientist and polymath who lived in the 17th century. He made significant contributions to the fields of physics, biology, and architecture. He is best known for his law of elasticity, known as Hooke's Law, which states that the force required to extend or compress a spring is proportional to the distance it is extended or compressed.

Q2. What is Hooke's Law and how is it used?

Ans. Hooke's Law states that the force required to extend or compress a spring is proportional to the distance it is extended or compressed. This law is used in many areas of science and engineering, such as in the design of suspension systems for cars and in the measurement of strain in materials.

Q3. What are some examples of Hooke's Law in everyday life?

Ans. Some examples of Hooke's Law in everyday life include the suspension systems in cars, which rely on springs to absorb shock and maintain stability, and the use of elastic materials in clothing and sports equipment to provide stretch and support.

Q4. What was Hooke's contribution to the field of microscopy?

Ans. Hooke is credited with developing one of the earliest microscopes and using it to observe and document the microscopic structure of various materials, including plants and insects. He also coined the term "cell" to describe the tiny structures he observed in plant tissue.

Q5. How did Hooke's work influence the scientific revolution?

Ans. Hooke's work was influential in the development of the scientific method, which emphasized empirical observation, experimentation, and the systematic organization of knowledge. His discoveries in the fields of physics, biology, and architecture helped to lay the groundwork for many of the scientific and technological advances that followed in the centuries to come.
