Sir Richard Arkwright 1732 – 92

Sir Richard Arkwright by Joseph Wright of Derby (1789)

Richard Arkwright was born in Preston, Lancashire, a self-educated man whose career began as a barber and wigmaker, for which he was reputed to use genuine human hair. His industrial knowledge led him to adopt the idea of a water-powered spinning machine that he patented in 1769. Called the water frame, the machine allowed mechanisation of what had previously been a cottage industry and brought spinning into the factory age. By 1782 he employed more than 5,000 workers in his cotton mills.

In 1775 he patented a carding engine, based on a hand-worked machine that had been invented earlier by Lewis Paul. Arkwright’s machine incorporated a crank and comb mechanism that drove the comb up and down and lifted the combed fibres onto a cylinder to create a continuous fleece for spinning.

Cromford

His first mechanised mill was built at Cromford, south of Matlock in Derbyshire. The site was developed only two years after the patent for the water frame was taken out and was the first water-powered mill in the world. The complex of workshops was powered by wheels driven by the Bonsall Brook, which flows into the River Derwent close to the site.

Arkwright was also generous to his workers, in common with other industrialists of later times, and built a number of houses in the nearby village for his staff. North Street is one of the best-preserved terraces, built in approximately 1777. One of the homes is now preserved as a Landmark Trust property and is available for holiday lets.

1905 – Einstein’s miracle year

Almost everyone has heard of e=mc2 – the formula behind the Theory of Special Relativity – but very few people realise that it was just one of Einstein’s significant scientific breakthroughs of the year. It might also be worth considering that this was just 4 years after the death of Queen Victoria. Few people would think of Einstein as being an eminent Victorian but in fact he was.

The first scientific paper that Einstein published in this year was on the photoelectric effect. It showed that light sometimes behaves like a stream of particles with discrete energies called “quanta” and sometimes behaves like a wave of energy. The paper earned him a Nobel Prize.

The second paper was on Brownian motion – a random motion that can be observed when very light particles (such as Indian ink) are suspended in a liquid (such as water). It is caused when the molecules of the liquid collide with the particles and propel them in different directions. The paper included an experimental test for the theory of heat.

The third paper was the most famous – the Theory of Special Relativity – that included the famous equation quoted above. Behind the equation is the idea that mass and energy are actually two versions of the same thing and the amount of energy contained in mass is related to a constant (c). And the other key idea is that space and time are related.
