Sir Basil Brooke (1576 – 31 December 1646), English metallurgist and recusant, inherited the manor of Madeley, Shropshire from his father.
The patent contained a clause prohibiting the import of steel, but he was unable to meet demand and was required to surrender his patent, although he evidently continued making steel, probably using iron from the Forest of Dean, though this was subsequently found not to be quite the best raw material.
In 1615, he and Richard Chaldecott of London took over two furnaces and a forge of the king's ironworks in the Forest of Dean, but in 1618, they were accused of illegal felling and their lease was suspended.
Brooke (with George Mynne and Thomas Hackett) leased all the king's works (four furnaces and three forges), but in 1633, new claims were made that the ironworks were having a disastrous effect on the Forest.
Brooke was also one of the leading English Roman Catholics of his time, and was said to have personal contact with James I and Charles I.
Late in 1643, he was implicated in a plot to divide Parliament and the City of London authorities with a view to preventing the Scottish army taking part in the English Civil War.
