A detailed view into the Welsh polymath who revolutionized navigation, astronomy, and economic policy.

While Joseph Harris may not be a household name, his contributions to science and public policy left a lasting impact on Britain and beyond. A protégé of Edmond Halley and a skilled artisan in mapmaking, Harris played a crucial role in advancing astronomy and navigation. His work influenced some of the most prominent scientists of his time, and as assay master at the Royal Mint, he helped standardize weights and measures, which shaped Britain’s economic policies in ways still felt today.

This profile restores Harris to his rightful place in history, revealing his role as both a scientist and a dedicated public servant. From recording the 1761 Transit of Venus to advising prime ministers on monetary policy, his life exemplifies the intersection of craftsmanship and governance. A tribute to one of Wales’s unsung intellectuals, Joseph Harris: Scientist, Artisan, Assay Master redirects our focus on the individuals who quietly shaped the modern world.
