In May 1852 a newspaper advertisement announced the sale of valuable land adjoining Bradfield Moor in Yorkshire. It appeared in the Sheffield Independent, a daily newspaper for the town of Sheffield which lay a few miles to the south. This sale of valuable land by Mr Joseph Hammerton of Walker House, Bradfield Dale, included 102- acres of ancient woodland and 7 acres of grassland with commanding views of the surrounding romantic scenery. It also suggested that this freehold estate would be the ideal place to build a summer residence and perfect to use as a Shooting Box in winter.¹
Sidney Jessop and eventful times at Thornsett
The offer was taken up by Sidney Jessop (1809-1871), a nobleman of the eminent Sheffield steel-making firm William Jessop and Sons. The business had been started as a small crucible steelmaker by his father William Jessop in 1830, but there were records of Jessops making steel in Sheffield as far back as 1774. When William Jessop died in 1835 it was taken over by his sons – Montague (1802-1841), Henry (1808-1849), Thomas and Sidney. Montague died soon after and Henry, who established an American branch of the company, also died, in New York at the relatively young age of 41. Their father had taken care not to make any of his sons ‘masters’ and set them to learn the rudiments of the business, often making them toil as hard as other working men.
Sidney, along with his older brother Thomas (more of which we will read about later), continued the firm between them and quickly established it as one of the town’s most reputable manufacturers of steel for the making of tools, saws and steel pens. They also became investors in the Sheffield, Wortley, Silkstone and Wakefield Railway Company.
Sidney lived at 31 Broom Grove Road in the well-heeled district of Broom Hall. The house had been left to his widowed mother, Rebecca, but it was Sidney’s income that provided for the family indulgence. When William Jessop and Sons opened a branch on Dale Street in Manchester it was Sidney who supervised operations. He would move to Shakespeare Street in Ardwick, a house he maintained until his death.
The estate at Thornsett Moor was ideally situated on the way to Manchester. Thornsett Lodge was probably built about 1855 but the architect remains unknown. It was undoubtedly built as a summer retreat and, being a keen sportsman, ideal for Sidney to use during the grouse shooting season. As early as 1858 he was entertaining a party of about fifty gentlemen for the ‘Glorious Twelfth’.
‘The weather was beautifully fine, the sun being exceedingly powerful until towards two o’clock, when the clouds wore a threatening aspect, and the sound of distant thunder attracted the attention of those who were unprepared for a storm. Vivid flashes of lightning, followed by loud peals of thunder, shortly afterwards came in quick succession. About four o’clock the storm became so violent that the sportsmen were obliged to leave the moors. The rain and hail stones descended heavily for a couple of hours, and then somewhat abated, the storm apparently travelling in the direction of Sheffield’.²
When Sidney bought the land at Thornsett he might not have been aware of an important development in the valley below. In 1856 there was talk that the Sheffield Waterworks Company was considering building a new reservoir in order to supply the quantity of water required by an Act of Parliament for the mills of the River Loxley. It became reality in 1859 when construction started and the landscape below Thornsett Lodge was obliterated by hundreds of workmen. In time the ‘Bradfield scheme’ planned to have four reservoirs in the hills surrounding the nearby village.
The work on Dale Dyke encountered frequent problems but by the end of 1863 the embankment was so far complete as to be ready for the reception of water. Through the winter the 76-acre reservoir filled and by March it was almost full. However, disaster was to strike on the evening of Friday 11th March 1864 when, during high winds, the embankment collapsed sending 3 million cubic metres of water down the Loxley valley towards Sheffield. The wall of water destroyed everything in its course and reached Malin Bridge and Hillsborough where the River Loxley met the River Don . The water then thundered towards the town centre and then in the direction of Attercliffe and Rotherham. Altogether at least 240 people died and more than 600 houses were damaged or destroyed by the flood.
It proved to be Sheffield’s worst disaster (although not its last) and the remains of Dale Dyke scarred the landscape on Bradfield Moor. The Mayor of Sheffield, none other than Sidney’s older brother, Thomas, quickly set up a relief fund for the homeless and the needy that eventually reached £49,650. Notwithstanding the huge loss of life and the prolonged work needed to rebuild the dam there was now a stigma attached to the area around Thornsett.
The flood may have prompted Sidney to put the Thornsett Lodge estate up for auction in 1869. When the bidding failed to reach its reserved price the lot was withdrawn and it remained in Jessop hands.³
Sidney Jessop always lived under the shadow of his remaining older brother. He had a retiring disposition and never took much part in public affairs although, for a time, he did represent the Park Ward in the Town Council, during which time he declined an invitation to become Mayor. After a period of indifferent health he died at his Manchester residence in January 1871. Such was the respect given to him by his workmen that the pall bearers at his funeral were eight of the company’s oldest employees. Sidney Jessop was buried at Ecclesall Church in Sheffield.
Thomas Jessop – hero of the town
Upon the death of Sidney, his brother Thomas Jessop (1804-1887) was left the sole proprietor of William Jessop and Sons. Thomas was already an extensive owner of landed property and now inherited the estate at Thornsett. He lived at Endcliffe Grange in Sheffield which remained his principal residence.
While Sidney was considered to have been the restraining influence it was Thomas who showed the most enthusiasm for growing the business of William Jessop and Sons. At the age of 28 he crossed the Atlantic and laid the foundations of the business that afterwards sprung up. It was also Thomas who saw further ahead and from the original premises on Blast Lane, next to the canal, he extended to Brightside, and a year later added the Kilnhurst works as a temporary establishment. The Brightside works grew until they occupied nearly 30-acres of land intersected by nearly three miles of railway lines. At one stage there were six water-wheels and 28 steam boilers needed to drive the engines, hammers and machines.
Thomas Jessop will always be remembered in Sheffield as the generous donor of the Jessop Hospital for Women, an institution that still exists today. It had first been established in 1864 on Figtree Lane and a new hospital was opened in 1878. His donation amounted to £26,000 and he explained that while serving as Mayor of Sheffield he had thought it necessary that the town’s women should have their own hospital. ‘He had now built the hospital, he had furnished it, he had given it to the trustees for the benefit of the town, and he asked them to assist him in supporting it’.⁴
The public career of Thomas Jessop dated back to 1843 when he was elected a councillor for the Park Ward. He retired from the Town Council in 1848 and devoted his attention to the family business. In 1863 Thomas was chosen as Master Cutler and decided to re-join the council becoming Mayor a month later.
William Jessop and Sons became a limited company in 1875. Through aggressive business deals and key contracts the firm had grown into a world reputed empire. Thomas believed that the firm had become so big that the responsibility had to be shared with younger shoulders and wanted to develop young fellows who would eventually support his own son, William. He agreed to sell the company’s estate and property to Mr D Chadwick, M.P., and prepared to retire from the business. In the years that followed the firm went through several years’ poor trading and became saddled with a large quantity of iron bought when the price was at its height. Thomas Jessop returned as Chairman and effectively saved the company when he gifted it £46,000.
After he inherited Thornsett Lodge Thomas used his wealth to acquire the Huggate estate, on the Yorkshire Wolds, between Driffield and Pocklington, extending to 4,000-acres. This property, along with several good farms, cost him £160,000. He also became the owner of Foston, some 600-acres near Driffield, which included a trout stream running right through the middle of it.
Thomas married Frances Yates Hope, daughter of Peter Hope, wholesale merchant and grocer of Liverpool, in the spring of 1846. Before this he had lived in his father’s cottage adjoining the Blast Lane works – ‘A beautiful place, with a lovely lake in the front, and delightful surroundings’. After marriage he lived at Claremont and later moved to Farm Bank on Shrewsbury Road, afterwards to Shirle Hill in Sharrow. Thomas Jessop bought Endcliffe Grange following the death of its owner Edward Fisher Sanderson. He extended and improved the house making it one of the most desirable residences in one of the wealthiest suburbs. He also embellished the interior with valuable works of art, including those by Osler, Pettie and other famous painters.
However, it was Thornsett Lodge where Thomas spent his long summers enjoying the view down the valley of the Loxley and the Porter, the Parish Church of Sheffield being discernible in the distance. During the grouse season he made a point of gathering friends around him, including members of the ‘Birthday Club’, meeting on market days at the King’s Head, and he always made a point of visiting Thornsett on the 12th of August.⁵
Thomas Jessop died at Endcliffe Grange in November 1887.
William Jessop – man of the land
The only son of Thomas Jessop was William Jessop (1856-1905) and now head of the third generation of the steel manufacturers. As a youngster he was educated at Collegiate School in Sheffield and later at Repton, in Germany, before finishing his education at Cambridge. For the greater part of his life he didn’t take part in the affairs of the business but finally became a director in 1880 and, on the death of his father, became its chairman. Although he didn’t take a prominent part in the day-to-day running he was influential in establishing a branch in America in 1902.
For some years he had been a director of the Sheffield and Rotherham Bank, and also occupied a seat on the board of the Yorkshire Engine Company. He also supported the work started by his father at the Jessop Hospital for Women and became president of the institution. This inspired him to also become a trustee of the Sheffield Royal Infirmary. Possessed of ample means and inheriting considerable landed estates from his father, William was more at home in the countryside.
William was keenly interested in agriculture, an ardent sportsman, who loved to handle the gun and rod and to play host to his sporting friends. As such he regularly visited Thornsett Lodge and owned extensive shooting rights in the Strines district, and became a prominent member of the Bradfield Game Association, a group of gentlemen who enjoyed grouse-shooting rights over a large area of the nearby moorland.
William was twice married. His first wife was Mary Crompton Bateman of Middleton Hall, Youlgreave, in Derbyshire. Her father and grandfather had been ardent antiquarians and were well-known in connection with their researches into the history of Derbyshire. By this marriage he had five children, four daughters and one son. Following the death of his first wife he married again, this time to Mrs Frances Jane Fenwick Watson, widow of Mr W.J. Watson of Newcastle.
For many years William resided at Forest Hill, near Worksop, and later moved to Wallingwells, an estate belonging to Sir Thomas White. For a time he moved to Endcliffe Grange while spending a few months each year at his house, 5 Westbourne Grove, in Scarborough. However, his liking for country life caused him to resume his occupancy of Wallingwells, where he remained until late in life. Here he indulged in hunting and shooting and could be regularly found with Lord Galway’s hounds when they were out. The tenantry on his estates found him an excellent landlord and he actively worked several of the farms on the Huggate estate. His open-handed generosity to those poorer than himself was evident in those times of agricultural difficulty and there were many who thought him an ideal candidate to take part in public affairs. However, William chose not to participate and preferred a quieter existence, one that had been deprived of his father.
At the Coronation of King Edward VI and Queen Alexandra he made generous arrangements for each of his tenants and workers at Foston and Huggate to enjoy a day of festivities. Each person received an invitation card illuminated in Coronation colours, on it were portraits of the King and Queen alongside the Royal arms. In the centre were views of Foston Church, Wold House, Huggate, and Thornsett Lodge. Below these were photographs of Thomas Jessop on one side, and his grandson on the other; with the host and hostess Mr and Mrs William Jessop between them. On the day itself each person was presented with a Coronation medal with a pendant ribbon of red, white and blue.⁶
During the last two years of his life William was struck down with a painful affection of the throat. In an attempt to rescue his health he journeyed around the world visiting Australia and Japan. William made several visits to London for medical consultations but it was apparent that he was gradually sinking. He left Wallingwells and made Thornsett Lodge his permanent home. It was here that he spent the last 12 months of his life, the last three being unable to leave the safe confines of the house, and here he died on 4 July 1905.
William Jessop bequeathed his wife a carriage, a pair of horses, harness, saddlery, and stable furniture, as well as wines and spirits and other consumable stores from Thornsett Lodge and Westbourne Grove in Scarborough. He gave her a legacy of £500 and the right to use Thornsett Lodge until his only son, Thomas Jessop, reached the age of 23. It would appear that she had no appetite for alcohol as the extensive cellar of vintage wines was auctioned the following November.⁷
Thomas Jessop and the extravagance ends
When William Jessop’s only son was born in 1888 it was quite right that he should be named after his famous grandfather. He was sent away to be educated in Cheltenham and enjoyed the sporting traditions available to a privileged young man. He was an amateur cross-country jockey and won numerous trophies at point-to-point meetings He was a first-class shot and a cricketer of some repute. In 1905, aged 17, he joined William Jessop and Sons but the death of his father a month later probably arrested any ambitions to serve the company.
It might also be the case that Thomas had little interest in Thornsett Lodge either. His step-mother, entitled to stay until he reached the age of 23, decided to take the sea air and had moved to 127 King’s Road in Brighton, Sussex. In 1908 Thornsett Lodge was advertised to let on a yearly tenancy. It was described with three reception rooms, twelve bedrooms, excellent servants’ offices, extensive stabling and outbuildings. It also came with relatively rare electric light installation and all modern conveniences.⁸
Thomas, like his father, enjoyed countryside pursuits and while in Gloucestershire had met a similar-minded person in Miss Bertha Muriel James, daughter of Mr A.B. James of Somerset and Mrs James of Park House, Thirlestaine Road, Cheltenham. They were married in July 1909 and the fact that Thornsett Lodge was still without a tenant provided the perfect opportunity to spend their honeymoon there.
The couple lived on private means and set up home at 25 Promenade, Moat House, Uckington, in Cheltenham, but there was also time spent in Lincolnshire. In 1906 he had obtained a commission with the Lincolnshire Yeomanry, serving under Lord Yarborough, with whom he served throughout World War One. He was on HMS Mercian when she was shelled in the Mediterranean with the loss of nearly 80 lives. He also saw several years’ service in Egypt and Palestine, much of which was with the Desert Mounted Corps.
Returning to England he settled in the Spilsby district of Lincolnshire and purchased Harrington Hall. He devoted much of his life to hunting, a passion shared with his wife. They had hunted throughout Britain from 1911 until he went to war and he was Master and Huntsman of the Boddington Harriers in Gloucestershire. In 1920 he became Joint Master of the Southwold Hounds and later hunted the Burton Hounds and then South Wold East.
Thornsett Lodge remained under his ownership but by the 1920s was being used by the Bradfield Game Association for shooting purposes. However, in 1928 the association had instructed the Sheffield auctioneer’s of Eadon & Lockwood to sell all the contents of the house.
Maybe Thornsett Lodge had too many close associations with Sheffield and its industrial past to satisfy Thomas Jessop’s rural pursuits. Whatever the reasons the house steadily fell out of favour with him as did the city that had allowed him to live the life of a country gentleman. (Ironically, his step-mother, Frances Jane Fenwick Jessop, had by now moved out of Brighton and had taken a house, ‘Thornsett’, on Falmer Road in Rottingdean. She died in May 1933).
Soon after the contents of Thornsett Lodge had been disposed of the house and estate were sold to Grange and Dale Ltd, a Lincolnshire based property investment company headed by Major Charles Wilson of Riseholme Hall and a Captain Hunt. It is not without probability that they were friends of Thomas Jessop and were keen to exploit the shooting moors that came with the lodge.
The house was made available to let and in 1933 it was home to Gladys Hilda Wyles, spinster, whose only claim to fame appears to be the bankruptcy of her Mowbray Confectionery Works, a wholesale and manufacturing confectioner in Sheffield.
In 1934 Grange and Dale Ltd sold Thornsett Hall to Sheffield Corporation most likely to be used as offices for the waterworks department who were responsible for the nearby Dale Dyke, Strines, Agden and Damflask reservoirs. Grange and Dale Ltd retained the shooting rights and were still advertising that the grouse moors were available to let as late as 1940.
As for Thomas, during World War Two he served as a Welfare Officer in the Northern Command, based in Lincoln, and would later become Major Thomas Jessop. He went on to serve with Spilsby Rural District Council and its committees but it was with the company of ex-servicemen that he enjoyed his role as President of the Lincolnshire Yeomanry Old Comrades’ Association as well as being patron of the Spilsby branch of the British Legion.
While Thomas lived his peacetime in relative comfort, and on the proceeds of William Jessop and Sons, it was apparent that times were changing. Between the wars his move from Harrington House to the smaller Harrington House Farm in the adjoining village reflected the declining years of the steel business and a change in his personal circumstances. He died aged 65 at Horncastle Hospital in February 1952.⁹
Decline and fall
The prospect of war loomed over Europe and in May 1939 it was announced that Thornsett Lodge would house infants from Herries Road Nursery ‘in case of emergency’.¹⁰ This was exactly what happened and the youngsters enjoyed the fresh country air while the city below worked itself to exhaustion and suffered at the hands of German bombers.
It was the start of a long association with children and when peace returned Thornsett Lodge was used as an adjunct to Sheffield Corporation’s cottage homes at Fulwood. It was also around this time that the name appears to have been changed to Thornseat Lodge. A swimming pool was built at the rear of the house and in 1973 it was described as a mixed sex home for 16 emotionally disturbed or ‘difficult’ children of all ages. By 1978 it was listed as an Intermediate Treatment Centre accommodating 12 young people, but its days were numbered.
By the time of its closure in 1980 there was little to associate Thornseat Lodge with its glorious days of domestic pleasure. The 1980s were difficult times for the City of Sheffield. Unemployment was high; its infrastructure was struggling and the council was cash-strapped. There was little else to do but ‘mothball’ it until a better use came along.
The house was not entirely empty. In the early 1990s it was used by the Sheffield Gingerbread Group as a place for families on low incomes to go and stay. As one person said on the Sheffield History forum: – “We stayed there several years’ running. It was a beautiful old house with one room which the caretaker still used in its original state with oak panelled walls. We celebrated children’s birthdays, Halloween and lots more and it was great to see the kids out-of-town and into the countryside.”
But the good times weren’t to last. As the new millennium approached little was done to save Thornseat Lodge. The severe moorland winters were no match and the house quickly fell into a state of disrepair. The worse it became the less likely anybody was going to be interested in buying the property. In 1994 there were plans to turn Thornseat Lodge into a possible location for an eight-place secure unit but hesitancy by Sheffield City Council and opposition from the Peak National Park meant plans were quickly shelved.¹¹
In 2004 the council finally sold the property to Hague Plant Excavations Ltd whose ownership and intentions have been subject of much internet debate ever since. Most certain is that Thornseat Lodge has become a perilous ruin and, without listed status, its future is uncertain. A huge amount of money would be required to restore the property and for what purpose? The easiest option might be to demolish it once and for all but there might yet be salvation. In June 2016 a new company was formed called Thornseat Lodge Ltd. Its purpose is unclear but let us hope that there might be a happy ending for Sidney Jessop’s old shooting lodge after all.
Until then the ghosts will continue to wander through the open corridors, the crumbling stonework and the broken glass.
William Jessop and Sons, later William Jessop and Company, merged with J.J. Saville and Co to become Jessop Saville & Company. The Brightside Lane works in Sheffield closed in the late 1980s and was later cleared to become ‘Jessop’s Riverside’ business park. In 1998 the company was bought by Allegheny Teledyne.
