Henry Howard, 1st Earl of Northampton was an important English aristocrat and courtier. He was suspected throughout his life of being Roman Catholic, and went through periods of royal disfavour, in which his reputation suffered greatly. He was distinguished for learning, artistic culture and his public charities. He built Northumberland House in London and superintended the construction of the fine house of Audley End. He founded and planned several hospitals. Francis Bacon included three of his sayings in his Apophthegms, and chose him as "the learnedest councillor in the kingdom to present to the king his Advancement of Learning." After his death, it was discovered that he had been involved in the murder of Sir Thomas Overbury.

Northumberland House was a large Jacobean townhouse in London, so-called because it was, for most of its history, the London residence of the Percy family, who were the Earls and later Dukes of Northumberland and one of England's richest and most prominent aristocratic dynasties for many centuries. It stood at the far western end of the Strand from around 1605 until it was demolished in 1874. In its later years it overlooked Trafalgar Square.
