We add here some editorial matter related to the authors or topics that we publish.

1. MARCEL DUCHAMP WAS NOT A THIEF, from The Burlington Magazine, December 2019, by Dawn Ades and Alastair Brotchie. Claims that Duchamp stole “Fountain” from Elsa von Freytag-Loringhoven are reduced to provable facts in order to demonstrate that these claims are both wrong and dishonest.

2. MARCEL DUCHAMP AND THE BARONESS. Two letters from Dawn Ades and Alastair Brotchie published in The Art Newspaper in February and April 2020. These letters pursue the argument of 1 above, with responses by Julian Spalding and Glyn Thompson, and replies to those responses. The “controversy” is reduced to two simple questions which prove definitively that the Baroness played no role in “Fountain”.
