| 1736 | James is born on January 19th, in Greenock (near Glasgow); father is James Watt, a carpenter and shipwright, and treasurer and magistrate of Greenock; mother is Agnes Muirhead; a delicate child, James is taught until age eleven or so by his mother; he does not shine as student until grammar school, when under competent tutelage he excels at mathematics; he is not precocious, except in drawing; perhaps his most important experiences are in his fathers shop, where the younger James is set up with his own equipment and proves quite capable the workmen saying that "Jamie has a fortune in his fingers' ends". | There are numerous aspects of James' early life worth noting,
including the following:
|
| 1753 | His mother dies, when Jame is 17; James decides to become a mathematical instrument maker, and leaves for Glasgow, where he obtains an apprenticeship, but knows more that the man he works for. | Once again we see the familiar pattern where parental bereavement is associated with creative genius, although in this case involving a mother instead of a father (see Ochse, ch. 4, and Simonton, ch. 4). |
| 1755 | James leaves for London, where after some difficulty he is finally apprenticed to an instrument maker; he lasted only one year before his health began to fail him, due to his long hours and fragile constitution; nevertheless, James learned "more in one year than most journeymen in four". | James' professional life was affected directly by two gulfs
between professions:
|
| 1757 | Returning to Glasgow, he soon earned, through his friends, a position as "Mathematical Instrument Maker to the University". | |
| 1759 | Because the university work was not enough to sustain him, he in partnership with James Craig opened a shop in Saltmarket to make all sorts of instruments, including toys. | |
| 1764 | A momentous year in James' life: He marries his cousin Margaret Miller, who, before she dies nine year later, bears him six children; and in one of those serendipitous twists of human affairs, the university acquires a non-working model of a Newcomen engine, and Watt is asked to repair it. | It is often thought that Watt invented the steam engine, this is not true: Thomas Newcomen had built at Staffordshire, England, a working steam engine in 1712 Watt's genius was to make a steam engine of sufficient power, efficiency, and flexibility that it could drive the industrial revolution. |
| 1765 | Watt immediately sees the limitations of the Newcomen engine, and in May of 1765 comes up with his first and greatest invention, the idea of a separate condenser (to learn more about this, check out the web sites or the materials in your notebook). | Two things are noteworthy about this remarkable event:
|
| 176674 | Watt works as a land surveyor on Britain's new canals; he is only able to work sporadically on his steam engine designs. | |
| 1768 | James enters into a partnership with John Roebuck to make a prototype of Watt's improved steam engine. | |
| 1769 | Watt takes out his famous patent for "A New Invented Method of Lessening the Consumption of Steam and Fuel in Fire Engines". | |
| 1772 | Roebuck goes bankrupt, freeing Watt from their earlier agreement. | |
| 1775 | Watt forms a partnership with Matthew Boulton, a partnership which will last 25 years; they are the ideal pair Watt, the technically-gifted hypochondriac and genius, and Boulton, the wealthy, insightful, and opportunistic industrialist. | Also about this time begins the monthly meetings of the Lunar Society, an extremely influential, yet informal, group of industrialists and scientists, which included among its dozen or so members not only Watt and Boulton, but Joseph Priestley, Erasmus Darwin, William Small, and Benjamin Franklin as a corresponding member. |
| 1776 | Watt and Boulton build their first two engines at Boulton's Soho Iron Works in Cornwall; Watt remarries, his second wife, Ann MacGregor, bears him two children. | |
| 1781 | At Boulton's urging, Watt invents a rotary motion device for his steam engine, called a sun-and-planet gear, that adapts their steam engine for use in corn, malt, and cotton mills. | James Watt
|
| 1782 | Watt's father dies; James, at the height of his inventive powers, patents the double-acting engine, in which the piston pushes as well as pulls. | |
| 1784 | Watt improves the steam engine by inventing a parallel motion device for connecting the piston to the beam. | |
| 1785 | Watt and Boulton are elected members of the Royal Society of London (members of the Lunar Society revitalized the Royal Society, which had become a social rather than a literary club). | |
| 1788 | Watt invents, at Boulton's suggestion, the centrifugal governor for automatic control of the engine's speed. | |
| 1790 | Watt invents a pressure gauge to monitor and regulate the internal steam pressure of the engine; this last modification takes the Watt engine about as far as it can go. | By this time Watt is a wealthy man, based on royalties from his patents. |
| 17945 | Watt purchases a country estate at Doldowlod, Radnorshire, and begins to retire from business; Watt and Boulton establish the new firm of Boulton & Watt, which they turn over to their sons, James and Matthew. | |
| 1806 | James is made a doctor of laws of the University of Glasgow (and made a foreign associate of the French Academy of Sciences in 1816). | |
| 1819 | James dies, at Heathfield Hall, near Birmingham. | |
