During his residence Montagu House had been known as Frognal Grove, a name it retained during the residence of Edward Montagu, Esq., Master in Chancery, who, some time subsequent to 1769, tenanted it.[93] A man of sense and refined feeling, a philanthropist and practical benefactor to Hampstead, he was one of the leaders of a band of gentlemen who had wakened up from the general apathy as to the moral, social, and religious wants of their poorer neighbours, and who (to quote Park), ‘setting their faces against the drinking habits prevalent in mixed society, pledged themselves to keep within the bounds of temperance, and to introduce subjects, or topics of conversation, that should tend to improve the understanding and the mind. Under the ill-chosen name of _Philo-investiges_, the members of the society held their meetings at the Flask Tavern, and from the quarterly subscriptions, fines, etc., established a fund for charitable purposes.’[94] In 1787 the members, with Mr. Montagu at their head, founded the Hampstead Sunday-School, a proof that the intention of the society had been adhered to, and had borne fruit after its kind, for in those days, when neither national[95] nor other schools existed in villages for the children of the poor, the value of Sunday-schools could scarcely be overrated. Mr. Perceval also patronized this school. It is only just to say that the absolute founder of the Sunday-school was Mr. Thomas Mitchell, who kept a school at Hampstead for twenty-two years on week-days, and was so real a philanthropist that he continued the vocation on Sundays for the benefit of poor children. To return to Mr. Montagu. This gentleman was the trusted friend of Lord Mansfield, who placed in his hands his resignation of the Lord Chief Justiceship. After Mr. Montagu’s death, and in honour of him, Frognal Grove was called Montagu House, a name it still retains. Stevens, the Shakespearian annotator, had a house in Frognal before he purchased the premises of the Upper Flask, which is now known as Upper Heath. Previous to 1811 Lord Walpole had a residence at Frognal, which Mr. Thomas Kestevan afterwards bought for £400, the price of a very humble abode in the present day. At this time two of the four joint purchasers of the Belsize estate, German Lavie and James Abel, Esqs., were living in Frognal. Thomas Carr, Esq., had a residence here early in the present century, where Crabb Robinson was a frequent visitor. His house appears to have been the literary centre of this part of Hampstead, and the pleasant diarist tells us of meeting there on one occasion Sir Humphry Davy and his bride (Mrs. Apreece), the poet Wordsworth, and Joanna Baillie, adding that ‘Sir Humphry and Lady D—— seem hardly to have finished their honeymoon.’
