William Motherby (1776–1847) was the originator of the idea of an annual midday meal to celebrate Immanuel Kant on Kant's birthday, which is shared by members of the Society of Kant's Friends on 22 April every year. Until 1944 it was held in Königsberg. After the war it moved to Göttingen and, in 1976, to Mainz. In 2008 the celebration returned to the city now known as Kaliningrad, where it has been held annually since, now attended by Kant's admirers from a number of countries.[1][2]
