Brian McNeil[edit]

Brian McNeil in 2014

Brian died suddenly on 4 July. His many friends in the Wikimedia movement loved his irascible humour (on his Facebook profile he described himself as a "curmudgeonly bastard who will swear at you for being repeatedly stupid"), his staunch advocacy of Wikinews and Scottish independence, and his taste in hats.

Brian made just under a thousand Wikipedia edits between 2004 and 2018, but over 47,000 to Wikinews, where he was a bureaucrat, and also contributed to both Commons (3,825 edits) and Meta (>300).[1]

Alin Huțu (Silenzio76)[edit]

Admin at Romanian Wikipedia, chose euthanasia due to losing a battle with brain cancer.

Jerome Kohl[edit]

Jerome (Jerry) Kohl died August 4, at the age of 73. A world-renowned music theorist, he was one of the most prolific editors in Wikiproject Classical Music, specializing in music of the 20th and 21st centuries, as well as music of the medieval era. A stickler for facts, accuracy, and reliable sources, he maintained hundreds of articles, and was well-known to most editors in these topic areas. Jerry was collegial, funny, occasionally acerbic, and always responsive. He had a Ph.D. in music theory from the University of Washington (1981), on the music of Karlheinz Stockhausen, and become one of the world experts on his music; additionally he was a managing editor of the distinguished periodical Perspectives of New Music. On Wikipedia -- if it was twelve-tone, serial, avant-garde, outré, experimental, and loosely descended from the European classical tradition, it probably has Jerry’s fingerprints on it, and visitors to Wikipedia will be appreciating his work as long as the place endures. Ave atque vale; those of us who have worked with you will miss your precision, scope, and wit. There is now a biography at Jerome Kohl.

Paul T. McCain (Ptmccain)[edit]

Rev. Paul T. McCain was a Lutheran pastor and publisher[1] who contributed numerous images and amassed 1,600 edits to a variety of Lutheranism-related pages on Wikipedia in 2006. His passionately held views on these topics drew him into conflict with other editors, and after some time he was indefinitely blocked from editing. However, the website, which he personally operated and funded, continues to be used as a reference on Lutheranism-related Wikipedia articles.

Rev. McCain's colleague, Rev. Harrison, wrote that "Paul served as a pastor in Iowa, senior assistant to LCMS President A.L. Barry, and was serving as the Publisher at our Concordia Publishing House."[2]

Aditya Kabir[edit]

Aditya Kabir passed away on 9 December 2020, at the age of 50. He had 25,399 edits in Wikipedia. He was particularly active in articles related to Bangladesh and South Asia, and was involved in getting featured article status to the article Bengali language movement. He was instrumental in getting articles like Bikini, Sitakunda Upazila, Biman Bangladesh Airlines and Jayne Mansfield to good article status, among others. After several years of low activity, he again became fairly active in 2020. He was very helpful, and acted as mentor to many new users.
