John James Hughes  was a Welsh engineer, businessman and founder of the city of Donetsk. The city was originally named Yuzovka or Hughesovka (Юзовка) after Hughes, ("Yuz" being a Russian and Ukrainian approximation of Hughes) but was renamed Stalino in 1924 (in 1961 the name was changed again, to Donetsk).

Hughes was born in Merthyr Tydfil, Wales, where his father was head engineer at the Cyfarthfa Ironworks. It was there that Hughes started his career, under his father's supervision.

He then moved to Ebbw Vale, before joining the Uskside Foundry in Newport, Monmouthshire, in the 1840s. It was here than Hughes made his reputation and fortune, patenting a number of inventions in armaments and armour plating.

 The resultant revenues allowed him to acquire a shipyard aged 28, and by the age of 36 he owned a foundry in Newport. It was also during this time that he married Elizabeth Lewis, and had eight children: six boys and two girls, all born in Newport.

In the mid-1850s, Hughes moved to London to become manager of C.J.Mare's forges and rolling mills, which was then taken over by theMillwall Iron Works & Shipbuilding Company, part of the Millwall Iron Works, Shipbuilding and Graving Docks Company.

 Hughes was a director of the company when it floundered, and resultantly became manager of the residual Millwall Iron Works Company. During this period, the various companies and successors won worldwide acclaim for the iron cladding of wooden warships for the British Admiralty, for Hughes was given much of the credit.

In 1864 he designed a gun carriage for heavy cannons, which came to be used by the Royal Navy, as well as the navies of some other European countries.

In 1868, the Millwall Iron Works Company received an order from the Imperial Russian Government for the plating of a naval fortress being built at Kronstadt on the Baltic Sea.

Hughes accepted a concession from the Imperial Russian Government to develop metal works in the region, and in 1869 acquired a piece of land to the north of the Azov Sea from Russian statesmanSergei Kochubey (son of Viktor Kochubey).

He formed the 'New Russia Company Ltd.' to raise capital, and in the summer of 1870 aged 55 he moved to Russian Empire. He sailed with eight ships, with not only all the equipment necessary to establish a metal works, but also much of the skilled labour; a group of about a hundred ironworkers and miners mostly from South Wales.

Immediately he started to build metal works close to the river Kalmius, at a site near the village ofAlexandrovka. The state-of-the-art works had eight blast furnaces and was capable of a full production cycle, with the first pig iron cast in 1872.

During the 1870s, collieries and iron ore mines were sunk, and brickworks and other facilities established to make the isolated works a self-sufficient industrial complex. He further built a railway line producing factory. All of Hughes facilities were held under the 'Novorussian society for coal, iron and rails production.'

The Hughes factory gave its name to the settlement which grew in its shadow, and the town of Hughesovka (Yuzovka) grew rapidly. Hughes personally provided a hospital, schools, bath houses, tea rooms, a fire brigade and an Anglican church dedicated to the patron saints St George and St David.

The land around the metal works quickly grew to become an industrial and cultural centre in the region, with the population of the city founded by Hughes now exceeds 1 million.

Over the next twenty years, the works prospered and expanded, first under John Hughes and then, after his death in 1889, under the management of four of his sons. Amazingly, John Hughes was only semi-literate, he was unable to write and could only read capital letters.

Hughes died on June 17 during his business trip to St Petersburg at Angleterre Hotel. His body was immediately repatriated to the UK for burial; his wife had predeceased him in 1880 and he was buried beside her at West Norwood Cemetery. Several of his sons were taken there for burial when they died.

By the end of the nineteenth century, the works was the largest in the Russian Empire, producing 74% of all Russian iron by 1913.

 A period of relative decline in the early years of the twentieth century was followed by expansion during World War I, but the Bolshevik revolution of 1917 brought the Hughes family connection with the works to a close.

The Hughes brothers and almost all of their foreign employees left Russia, and the works were taken over by the Bolsheviks in 1919.

The town of Hughesovka was renamed first to Stalino, in 1924, and then Donetsk in 1961. The works survived and prospered, and Donetsk is still a major centre of metallurgical industries.

Many of the men who accompanied John Hughes settled in Hughesovka, bringing out their wives and families. Over the years, although a Russian workforce was trained by the company, skilled workers from the United Kingdom continued to be employed, and many technical, engineering and managerial positions were filled by British (and especially Welsh) emigrants. A thriving expatriate community was established, living in good quality company housing, and provided with an English school and an Anglican church.

Life could be hard, with very cold winters, hot summers, and occasional cholera epidemics, but some families remained in Hughesovka for many years. After the Bolshevik revolution, however, almost all returned to Britain, although a few stayed on, and their descendents still live in Donetsk.

In March 2014, following the annexation of Crimea by the Russian Federation, a humorous campaign was set up advocating that Donetsk join the United Kingdom because of the city's connection to Hughes.

 This would shortly precede Ukraine losing control of Donetsk to pro-Russian militants, with seizure of the city's administrative building by the self-declared Donetsk People's Republic, which has declared the city to be independent of Ukraine and advocates integration with Russia.

Also in 2014, an instrumental song on Manic Street Preachers' –a Welsh band– album Futurology paid homage to him, referring to Donetsk by its former name.
