Must Read

James Watt, a scientist, inventor, and visionary, demonstrated unwavering faith in his ventures despite encountering substantial financial, time, and design constraints. His aspiration to create instruments and his capability to construct his own steam engine played a pivotal role in driving the Industrial Revolution. Notably, he is the brilliant mind behind the concept of horsepower. As the father of the Watt Steam Engine, James Watt stands as an inspirational figure, and his contributions have left an indelible mark on the trajectory of industrial history.

A lie can run around the world before the truth can get it’s boots on.

Born: 19 January 1736, Greenock, Renfrewshire Scotland

Died:  25 August 1819, Handsworth, West Midlands, United Kingdom

James Watt encountered numerous obstacles on his path to success, overcoming them through sheer hard work. His life achievements stand as significant milestones, serving as inspiration for future generations. Let’s delve deeper into his remarkable journey from ashes to glory:

  • Childhood: James Watt was born on 19 January 1736 in Greenock, Renfrewshire. He was the eldest among the five surviving children of Agnes Muirhead (1703–1755) and James Watt (1698–1782). Due to his ill health, which included migraines and toothaches, James received most of his early education at home, where his mother played a significant role as his tutor. He later attended Greenock Grammar School.
  • In addition to his formal education, James Watt acquired practical skills in carpentry and navigational aids from his father. His father, a carpenter and shipwright, had successfully transitioned into a merchant and ship-owner. Under his father’s guidance, Watt gained knowledge in carpentry and learned about essential navigational tools like quadrants, compasses, and telescopes. This hands-on experience provided Watt with a well-rounded skill set that would later contribute to his success as a scientist and inventor.
  • In 1754, Watt moved to Glasgow, Scotland, with the intention of setting up his own instrument-making business. It was during this period that he crossed paths with Robert Dick, a scientist at the University of Glasgow. Impressed with Watt’s foundational instrument-making skills, Dick advised him to go to London for further training to enhance his expertise. Watt spent two years undergoing instrument-making training in London before returning to Glasgow in 1756.
  • A Desire to Make Instruments: Watt had set up his instrument manufacturing shop in Glasgow but experienced difficulties finding enough work due to the unfriendly competition from other instrument makers. In response, he diversified his production by crafting musical instruments, a strategic move to sidestep direct competition. To everyone’s surprise, Watt’s musical instruments surpassed the quality of all existing models in the market, resulting in significant growth in his business. In 1758, he received funding from an architect to construct a new shop in the heart of Glasgow, marking a pivotal moment in his entrepreneurial journey.
  • Building Professional Relationships: In 1759, James formed a partnership with John Craig, an architect and businessman, to jointly manufacture musical instruments and toys. This collaborative venture endured for six years, during which it employed up to sixteen individuals.
  • Development of Steam Engine: In a crucial moment in 1763, University Professor John Anderson presented James Watt with a new challenge. The University had built a lab-scale model of the Newcomen steam engine to understand the excessive steam requirements of the full-scale pumps. Watt identified the flaw in the model, caused by an undersized boiler incapable of supplying sufficient steam to reheat the cylinder after a few strokes. This revelation marked the beginning of Watt’s groundbreaking contributions to the development of the steam engine.
  • Watt dedicated months to contemplating the problem at hand, conducting several experiments in the process. Throughout this intensive period of exploration, he delved into the intricacies of steam properties. In a noteworthy development, Watt independently discovered the concept of latent heat of vaporization during one of his experiments.
  • Business Partnership: James Watt’s path to success took a crucial turn when he crossed paths with John Roebuck, an influential industrialist holding coal leases. Witnessing the potential of Watt’s model in action, Roebuck decided to finance the development of a full-scale engine. Not only did Roebuck fund Watt’s engine patent, granted in 1769, but he also took on the responsibility of clearing all debts from Watt’s instrument shop. In return for this financial support, Roebuck secured a two-thirds share of the profits from Watt’s innovative steam engine.
  • Setback: Unfortunately, Watt faced a significant obstacle in realizing his dream due to a shortage of skilled manpower. Frustrated and facing financial pressures, he reluctantly quit the instrument-making business in 1771. The challenges persisted, and in 1772, Watt’s partner, Roebuck, experienced financial turmoil, declaring bankruptcy.
  • Silver Lining: The clouds began to lift for James Watt when businessman Matthew Boulton stepped in to acquire the assets of John Roebuck, including the patent for Watt’s engine. Boulton not only provided essential instruments but also offered unwavering support to help Watt realize his dream. This fortuitous turn of events led Watt to join forces with Boulton in May 1774, marking the beginning of a collaborative partnership that would propel Watt’s revolutionary steam engine to new heights.
  • Watt’s engine used a minimal amount of fuel as compared to the Newcomen engine. Eventually, it was welcomed hands-on by the purchasers.
  • Under Matthew Boulton’s guidance and encouragement, James Watt built more engines for different industries, such as the weaving and grinding industries. Recognizing the versatility and potential of Watt’s invention, Boulton played a pivotal role in diversifying its usage. In 1776, this collaborative effort resulted in the creation of the Watt Steam Engine, considered the world’s first modern steam engine.
  • Other Inventions: Watt’s other significant discoveries and inventions include a copying machine and an improved manufacturing process for chlorine bleaching agents. He also developed the concept of horsepower, a unit of measurement used to compare the output of steam engines with the power of draft horses. In 1889, ‘Watt’, the unit to measure power incorporated in the International System of Units (SI), was named in honour of James Watt.
  • Marriage: On 16 July 1764, Watt married his cousin Margaret Miller. They had two children, Margaret (1767–1796) and James (1769–1848). In 1773, his wife Margaret passed away. In 1775, he married Ann MacGregor.
  • James Watt devoted his remaining years to research after taking retirement in 1800. Watt, aged 83, died on 25 August 1819, and was buried alongside Matthew Boulton, at St Mary’s Church Birmingham.
