1 Stephen Gray (1666-1736)
STEPHEN GRAY (1666-1736) Canterbury dyer and amateur scientist © 2015 David R Lewis The influx of French Protestant silk weavers in the 17th century brought with it a growth in allied trades, including that of the dyeing of fabrics. Mathias Graye (buried Canterbury 1683), son and grandson of blacksmiths, became a dyer1. Mathias married Anne Tilman in 16582 and had four boys and three girls. One of the boys, Stephen, born in 16663, the year of the Great Fire of London, is the subject of this article. His older brother Thomas (baptised at All Saints Canterbury 1659) took over the family dyeing business but died in 1695, when the business passed to Stephen. Another brother, Mathias (baptised All Saints Canterbury 1661) became a grocer and served twice as city mayor4. We know nothing certain about Stephen's education. Records of King's School make no reference to him, but this apparently does not rule out the possibility that he attended to school as a 'Commoner'. The school conducted at Poor Priests Hospital is another possibility, but there is no evidence to confirm this either5. Gray's dyeing business started in Best Lane and moved to Stour Street (now Canterbury Cycle Centre) The family dyeing business was conducted initially in Best Lane but later in Stour Street. An image reproduced in Clark (1979B) clearly shows the south east side of Best Lane (by the Thomas Becket pub), but this seems implausible as the Stour backs the properties on the other side of the street - that shown in the image above. The Canterbury Cycle Centre premises were used for dyeing work up until recent decades (Beasley and Son dyers is shown in Kelly's 1961 town directory).

Experimental Philosophers and Public Demonstrators in Augustan England
13 J B)HS, 1995, 28, 131-56 Who did the work? Experimental philosophers and public demonstrators in Augustan England STEPHEN PUMFREY* The growth of modern science has been accompanied by the growth of professionalization. We can unquestionably speak of professional science since the nineteenth century, although historians dispute about where, when and how much. It is much more problematic and anachronistic to do so of the late seventeenth century, despite the familiar view that the period saw the origin of modern experimental science. This paper explores the broad implications of that problem. One area of scientific activity, public science lecturing and demonstrating, certainly produced its first professionals in the period 1660-1730. This was a period which Geoffrey Holmes called 'Augustan England', and which he found to be marked by the expansion of many of the professions.1 Swollen lower ranks of physicians, civil servants and teachers crowded onto the ladder up to gentility, and even solicitors achieved respectability. Alongside these established types the professional scientist, such as the public lecturer, was a novelty. Later, in the high Georgian era, a small army of men like Stephen Demainbray and Benjamin Martin made recognized if precarious livings from public experimentation, but the first generation pioneers were entering new and risky territory. As Larry Stewart has shown, 'the rise of public science' was a successful social and economic transformation of the highest significance in the history of science which was part of what has been called England's commercial revolution.2 We are accustomed to think of early, pioneering professionals like Robert Hooke, Francis Hauksbee or Denis Papin as 'notable scientists'.

Science: Electric Experiments. Stephen Gray
Science KS2- 3 Background notes Science in the Great Chamber: Stephen Gray p1 Years 6-8 Experiments in electrostatic electricity p2 History of Science Francis Hauksbee: Forgotten pioneer of science p3 Science in the Great Chamber Electricity: Stephen Gray and experiments in conductivity and insulators Long before Franklin famously flew his kite, a resident Brother of The Charterhouse, Stephen Gray – conducted ground-breaking experiments into electrical conductivity in the Great Chamber using a glass jar static electricity generator, (a Hauksbee Machine) and a handy schoolboy, suspended from silk ropes and some gold leaf flakes. (The boy was unharmed but don’t try this at home!) Gray was a keen amateur astronomer and close friend and associate with John Flamsteed – the first Astronomer Royal at the Royal Observatory in Greenwich. As such, his scientific career was somewhat thwarted by the long-running academic feud between Flamsteed and Sir Isaac Newton of the Royal Society and was excluded from membership of this key academic institution. Despite ground-breaking work in conductivity of electricity and periods of recognition, he ended his life in poverty, and became a Brother in the Charterhouse. His experimentation continued however with popular, public experiments, 1 conducted in the Great Chamber and he was finally granted honorary membership of the Royal Society a few years before his death in 1736. Gray’s experiments demonstrated that electricity ‘flowed’ along certain materials and not others. His work effectively pioneered the understanding of electrical conductivity and flow, along with insulation, which makes the power of electricity useable.
