Prestonian lectures

William Preston (1742-1818), a very active Freemason at the end of the eighteenth and the beginning of the nineteenth centuries, developed an elaborate system of Masonic instruction, by means of catechetical lectures, which was practised in association with the Lodge of Antiquity of which he was, at one time, Master.
At his death, he bequeathed to Grand Lodge the sum of £300, the interest from which was to be applied to some well informed Mason to deliver annually a Lecture on the First, Second or Third Degree of the Order of Masonry, according to the system practised in the Lodge of Antiquity during Preston's Mastership.
With occasional intermissions, lectures on his method were accordingly delivered from 1820 until 1862, when the Lectureship was allowed to lapse. In 1924 it was revived, with certain modifications of the original scheme: the lecturer delivering a paper on a Masonic subject of his own selection.
The Prestonian Lecture is the only lecture held under the authority of the United Grand Lodge of England and, with the exception of the years 1940-46, regular appointments have been made annually since 1924 to the present day. The list of brethren so honoured and the titles of their lectures appear at the end of the Masonic Year Book.
