The photograph shows the marble monument to Joseph Butterworth, Esq. (1770-1826) inside Wesley's Chapel, City Road.
Joseph Butterworth was a law bookseller with large premises in Fleet Street. Later, he became Member of Parliament for Coventry (1812-18) and Dover (1820-26). Many leading philanthropists of the day met at his London house, including William Wilberforce and Zachary Macaulay, the historian.
Butterworth was a Wesleyan Methodist and the first meetings of the British and Foreign Bible Society took place at his home. In 1819, he was appointed general treasurer of the Wesleyan Methodist Missionary Society.
