BRANDE, William Thomas (1788–1866), chemist. Autograph letter signed to R.Stevens Esq, Secy. L.I., 4to, 1 side, Clarges Street [London], April 16th 1819, relating to the delivery of lectures - "I have this day been favoured with your communication, relating to the Lectures at the London Institution and am very sensible of the honor conferred upon me by the Board of Management. I shall be prepared to deliver an introductory discourse on Wednesday the 5th of May at one." Small bits missing from corners where removed from an album.
In 1812 Sir Humphry Davy resigned his professorship at the Royal Institution, and the post was offered to Brande the following year. Here he had at his disposal the best-equipped laboratory in Britain, and he began to deliver a series of lectures, many being the basis for his major publications. In 1819 he delivered the first lecture and course at the newly built London Institution, founded in imitation of the Royal Institution, to which this letter would appear to relate. (ODNB)
