The Blue Plaque Places website tells us about Hester and Henry Thrale:

Henry Thrale (1724/1730?–4 April 1781) was an 18th-century English Member of Parliament (MP) and a close friend of Samuel Johnson. Like his father, he was the proprietor of the large London brewery, H. Thrale & Co.Born at the Alehouse in Harrow Corner, Southwark, he was the son of the rich brewer Ralph Thrale (1698–1758) and Mary Thrale. He married Hester Lynch Salusbury on 11 October 1763; they had 12 children, and she outlived him. He was MP for Southwark 23 December 1765 – September 1780, an Alderman, and Sheriff of the City of London: a respected, religious man who was a good hunter and sportsman with a taste for gambling.

Hester Lynch Thrale (born Hester Lynch Salusbury and after her second marriage, Hester Lynch Piozzi) (27 January 1741 [NS] – 2 May 1821) was a British diarist, author, and patron of the arts. Her diaries and correspondence are an important source of information about Samuel Johnson and 18th-century life.
