John Winter

Sir John Winter also spelt Wintour and Wyntour (about 1600–1676) was an English ironmaster and landowner at Lydney in Gloucestershire, who was an ardent supporter of Charles I during the English Civil War.

Biography John Winter was one of the grandsons of Sir William Wynter, Vice-Admiral of England, who was granted the manor of Lydney in the Forest of Dean. His parents were Sir Edward Wynter and Anne, daughter of the Earl of Worcester.

The Forest of Dean contained rich deposits of iron ore and, with charcoal made from its timber, had been the location of ironworks back to Roman times. Edward Winter had invested in iron making and John continued this family business. There was widespread local opposition to Winter's interference with established commoners' rights in the Forest of Dean. In 1624 it was claimed that Winter "and other Papists" were storing gunpowder and ammunition at his uncle's fortress, Raglan Castle and were plotting rebellion against King James. He obtained a 21-year lease from the Crown for forty thousand cords of wood in 1628, but had to give this up in 1634 when a forest eyre found that he had exceeded his rights. This was the first such court to have been held in the Forest for three hundred years and followed the Skimmington riots of 1631, in which the common people had protested against his enclosures.

On 20 February 1640, Sir John paid £10,000 for all the mines, minerals, and stone-quarries in the Forest of Dean, together with rights to all the timber, trees, woods and underwood growing there. In addition he agreed to pay £16,000 for six years, and a fee farm rent of £1950 12s. 6d. in perpetuity. He soon had fifteen furnaces and twenty forges with a capacity of six thousand tons, making him the second largest ironmaster in the country. As a committed Catholic and private secretary to the Queen, his allegiance to King Charles was expected, but he did not declare until the siege of Gloucester. In 1642 Winter tried to send cartloads of armaments from his residence at Lydney to Gloucester, and the following year fortified his house against attack. His house at Lydney, White Cross Manor, had been fortified. In April 1645 he ordered it burnt to avoid it being taken over by the Parliamentarians.

After the Restoration, Winter maintained his interest in the iron industry, and experimented with a new type of coking oven, which foreshadowed the work later achieved successfully by Abraham Darby on smelting iron with coke.
