   James Watt was born in Greenock, Renfrewshire, beginning a life that would connect Scottish scientific work with industrial engineering in Britain. Coordinates represent central Greenock; the precise birth-house location is not established by this source.

2. Instrument-making training in London

   1755-01-01 · London, England

   

   At age eighteen, Watt travelled to London for a year of instrument-maker training before returning to Scotland. The source supports a training period spanning 1755–1756; the card date marks its documented beginning.

   Watt began operating a small workshop within the University of Glasgow, maintaining and making scientific instruments and building relationships with Joseph Black and Adam Smith. The eighteenth-century university site was on High Street; coordinates represent Glasgow because the source does not specify the workshop's exact position.

5. Initiation at Glasgow Royal Arch Lodge

   1763-01-01 · Glasgow Royal Arch Lodge, Glasgow, Scotland

   Watt personally travelled to Cornwall to supervise erection of the first Boulton and Watt pumping engines, arriving at Chacewater to oversee the Wheal Busy installation. The source places this visit after materials were shipped in mid-1777; it does not supply a precise arrival date.

10. Residence at Regent Place

    1777-01-01 · Regent Place, Jewellery Quarter, Birmingham, England

    

    Watt lived at Regent Place in Birmingham during the formative years of the Boulton and Watt partnership and development of rotary steam-engine technology. The original house has been demolished; coordinates mark Regent Place in the Jewellery Quarter.

    1778-06-01 · Redruth, Cornwall, England

    

    On a further Cornwall journey to attend to the Tingtang engine, Watt reached the district in early June and established himself at Redruth. The source gives only 'the beginning of June'; month-level precision is used.

12. Chlorine experiment in Paris

    1786-01-01 · Paris, France

    

    During a late-1786 stay in Paris, Watt witnessed Claude Louis Berthollet produce chlorine, informing Watt's subsequent bleaching experiments in Britain. The source supports late 1786 but not a more precise date.
