Derby Silk Mill, is a museum of industry in Derby, England.
The museum is housed in  a historic former silk mill which is part of Derwent Valley Mills.
 Between 1717 and 1721 George Sorocold built Britain’s first mill beside the River Derwent.
This mill was built to produce silk threads using machines powered by a water wheel.

John Lombe copied the design for the machines used for spinning large quantities of silk, when he was working within the Italian Silk Industry.
This may be the first example of industrial espionage.

Traditionally the spinning wheel had been used for producing small quantities of silk thread at the homes of local spinsters.
But these new, large machines were able to produce far greater quantities of silk and came to compete with the Italians.
However, these machines required large buildings and a huge power source.
An undershot water wheel turned by the mill fleam on the west side of the new Silk Mill drove these large spinning machines.

John Lombe unnaturally died in 1722.
It was believed that he was killed with poison by an Italian as the revenge for stealing trade secrets.
His half brother, Sir Thomas Lombe Knt.,
died on 2 June 1739 leaving his estate to his widow and their two daughters.

Dame Elizabeth advertised the lease of the building and machinery in 1739, and the remaining 64 years of the lease were assigned to Richard Wilson junior of Leeds for £2,800.

Richard Wilson stayed in Leeds and took a proportion of the profits.
The mill was conducted by William and Samuel Lloyd (both London merchants) and Thomas Bennet as salaried manager.

A description of the mill by William Wilson dating from sometime between 1739 and 1753 is left as follows:
“
The original "Italian" works of five storeys high housed 26 Italian winding engines that spun the raw silk on each of the upper three floors whilst the lower two storeys contained eight spinning mills producing basic thread and four twist mills.

”
These circular spinning machines (also known as 'throwing machines'), were the most progressive feature of the factory.
Also, they used the single source of power (water), and employed many organized workers (200-400, according to recent sources).
Due to these total process of production from raw silk to fine quality thread, the Lombes' silk mill is regarded as the first successful use of the factory system in Britain.

The Silk Mill was visited by many tourists.
For example, Boswell visited there in September 1777.
Not all visitors thought that the mill was in good condition.
Torrington commented on the "heat, stinks and noise".
In 1835, Fairholt was shocked at unhealthy poor children.
Foreign visitors also visited the mill during their trips.

William Hutton was once the employees and he later recalled the long hours, low wages and beatings.
Work only stopped in time of extreme dryness or frost, or lack of silk supply.
But in August 1748, unofficial holidays were taken during elections and Derby races.

The partnership of Wilson and Lloyd ended in 1753 due to quarrel and legal suits.
Lloyd remained in possession of the building and machinery.

In 1765 Thomas Bennet bought the mill from Lloyd subject to a mortgage to the Wilson family but the mill was neglected for years, because other mills in Derby and Cheshire had grown to become competitor, and silk trade itself had declined.

Lamech Swift became the sub-tenant in 1780.
He paid £7 to the Corporation and £170 to Thomas Wilson (brother of Richard and William) per year respectively.
He conflicted with the Corporation on repairs to dams in 1781, he remained in occupation until the lease expired in 1803.

The Corporation advertised the lease in 1803 to run for 60 years.
The advertisement said that the "Italian works" was still used for throwing silk.

In November 1833, labor movements began in Derby which led to the formation of the Grand National Trades Union in February 1834.
Several months later, Tolpuddle Martyrs occurred.
The Silk Mill was not at the centre of the movements, Taylor (the mill's lessee at this time) was one of the employers who agreed not to empl
