Robert Hooke, Fellow of the Royal Society (FRS) (July 18, 1635 – March 3, 1703) was an English scientist, mathematician and architech who played an important role in the scientific revolution, through both experimental and theoretical work. He coined the term "cell" to refer to the structural and functional unit of living organisms and
Early life
Robert Hooke was born in Freshwater on the Isle of Wight in England. His father was John Hooke, curate of the Church of All Saints, in Freshwater, Isle of Wight.
From early childhood, Robert Hooke was fascinated by the sciences. Like his three brothers (all ministers), Robert was expected to succeed in his education and join his father's church. However, Hooke continually suffered from headaches while studying. His parents, fearing he would not reach adulthood, decided to give up on his education and leave him to his own devices.
Hooke received his early education on the Isle of Wight and, from about the age of 13, at Westminster School under Dr. Busby. In 1653, Hooke secured a chorister's place at Christ Church, Oxford. There he met the chemist (and physicist) Robert Boyle, and gained employment as his assistant. It is possible that Hooke formally stated Boyle's Law, as Boyle was not a mathematician.
Career
In 1660, Hooke elucidated Hooke's Law of elasticity, which describes the linear variation of tension with extension in an elastic spring. In 1662, Hooke gained appointment as Curator of Experiments to the newly founded Royal Society, and took responsibility for experiments performed at its meetings.
In 1665, Hooke published a book entitled Micrographia which contained a number of microscopic and telescopic observations, and some original observations in biology. Hooke coined the biological term cell, so called because his observations of plant cells reminded him of monks' cells, which were called "cellula." He is often credited with the discovery of the cell, and although his microscope was very basic, research by British scientist Brian J. Ford has now shown that Hooke could have observed cork cells with it. Ford furthermore shows that Hooke used more high power single lenses to make many of his studies. He also has identified a section in the Preface that contains a description of how to make a microscope, and Hooke's design was utilized by the Dutchman Anton van Leeuwenhoek, described as the father of microbiology.
The hand-crafted, leather, and gold-tooled microscope that Hooke used to make the observations for Micrographia, originally made by Christopher Cock in London, is on display at the National Museum of Health and Medicine in Washington, DC.
In 1665, Hooke gained appointment as Professor of Geometry at Gresham College. Hooke also achieved fame as Surveyor to the City of London and chief assistant of Christopher Wren, helping to rebuild London after the Great Fire in 1666. He worked on designing the Monument, Royal Greenwich Observatory and the infamous Bethlem Royal Hospital (which became known as 'Bedlam').
Hooke died in London on 3 March 1703 (ns). He amassed a sizeable sum of money during his career in London, which was found in his room at Gresham College after his death. He never married.
No portrait
It seems that no authenticated portrait of Hooke survives. (Newton instigated the removal of Hooke's portrait in the Royal Society.) In 2003, the historian Lisa Jardine claimed a recently discovered portrait represents Robert Hooke. However, Prof. Jardine's hypothesis was soon disproved by Prof. William Jensen (University of Cincinnati) and independently by the German researcher Andreas Pechtl (Johannes Gutenberg University, Mainz). Actually, the portrait is held to represent Jan Baptist van Helmont. A seal used by Hooke displays an unusual profile portrait of a man's head, that some have argued portrays Hooke. Both these claims remain in dispute, however. Moreover, the engraved frontispiece to the 1728 edition of Chambers' Cyclopedia shows as an interesting detail the bust of Robert Hooke.
Hooke the architect
Robert Hooke was an important architect. He was the official London Surveyor after the Great Fire of 1666, surveying about half the plots in the city. As well as the Bethlem Royal Hospital, other buildings designed by Hooke include: The Royal College of Physicians (1679); Ragley Hall in Warwickshire; and the parish church at Willen, Milton Keynes (historical Buckinghamshire).
Hooke's collaboration with Christopher Wren was particularly fruitful and yielded The Royal Observatory at Greenwich, The Monument (to the Great Fire) and St Paul's Cathedral, whose dome uses a method of construction conceived by Hooke.
In the reconstruction after the Great Fire, Hooke proposed redesigning London's streets on a grid pattern with wide boulevards and arteries along the lines of the Champs-Élysées, (this pattern was subsequently used for Liverpool and many American cities), but was prevented by problems over property rights. Many property owners were surreptitiously shifting their boundaries and disputes were rife. (Hooke was in demand to use his competence as a surveyor and tact as an arbitrator to settle many of these disputes.) So London was rebuilt along the original mediaeval streets. It is interesting to note that much of the modern-day curse of congestion in London has its origin in these petty disputes of the 17th century.
