Barnett House instituted a special annual lecture soon after it was founded in 1914. The first lecture was given in 1917 and published as the Barnett House Papers No. 1 by Oxford University Press in the same year. Sidney Ball, chairman of the Barnett House Committee, died in March 1918. A memorial endowment was established in his name and the first Sidney Ball Memorial lecture was delivered on 1 December 1920 by the Right Hon. Sir Horace Plunkett.
Plunkett began this first lecture: “I have the honour to inaugurate [the memorial lectures] today. Their aim will be the promotion of an intimate and mutually helpful relationship between the thought of the University Sidney Ball adorned and the working life of the community he lived to serve.”
Barnett House retained copyright over the lectures except that delivered by John Maynard Keynes in 1924. Where available, texts or recordings are linked below.
