Dr. Cornelius George Boeree was a Dutch-born American psychologist and professor emeritus at Shippensburg University, specialising in personality theory and the history of psychology. Born in the Netherlands, he moved to the States as a child, and grew up in New York. He was professor emeritus at Shippensburg for over thirty years. The inventor of the constructed language Lingua Franca Nova (ISO 639-3: lfn), which appeared in 1998, he was most active on his language's Wikipedia, where he had over 9000 edits. Globally, he edit count exceeded 11,000. His last edit was on 13 December 2020 on LFNWiki.

George died at home on 5 January 2021, aged 68. His death was reported on by The Sentinel.

Father John H. Zupez, editing as Jzsj, had been a Wikipedian since April 2015, with more than 30,000 edits. He created 420 articles, mostly about Jesuit schools and other religious topics. He died on February 21, 2021. He was born in St. Louis on October 21, 1936, and was ordained to the priesthood in 1967. He held various teaching positions and served as a pastor. His final assignment was to serve as a prison chaplain in the Diocese of Kansas City–Saint Joseph. Besides Wikipedia, he wrote articles to various Catholic magazines and newspapers until the very end. His last Wikipedia edit was on 24 December, 2020.

His death was reported by the Central and Southern Jesuits.

Dr. John Nathan Shutt died suddenly on February 25, 2021, at age 56. As well as making over 3,000 edits to Wikipedia since 2007, he was deeply involved with the sister projects Wikibooks, where he was an administrator, and the English Wikinews, as bureaucrat, making nearly 240,000 edits in total. His mother was Elsie Shutt, the noted technology entrepreneur. His death was reported on Wikinews.

Yoninah's final edit was on 18 January 2021, an abrupt end to a long and prolific tenure on Wikipedia. At the time, she was among our 400 most active editors. She was especially active at "Did you know?" (DYK), where she mentored new contributors, reviewed nominations, and prepared sets of "hooks" to be published on the Main Page. Over the years, there had been offers to nominate her as a Wikipedia admin, but Yoninah politely refused each time, saying she was happy just being an editor. She was so omnipresent on the DYK project, that her sudden absence was felt immediately among the community. Several editors began to post on her talk page on 28 January, ten days after her final edit, to wish her well and hope for her speedy return. Sadly, she never did.

Yoninah was an editor since 3 July 2005, first interested in Roots: The Saga of an American Family. She resided in Jerusalem and identified as a Jewish professional editor, writing articles for Wikipedia about (in her order) rabbis, Breslov personalities, Jewish personalities, Hasidic dynasties, yeshivas, streets, neighborhoods, landmarks, cemeteries, Jewish themes, books and films. She might have also included food and women biographies among her contributions. Some of her articles reached Good Article status, including Birds' Head Haggadah, Chaim Topol, Chavrusa, Downtown Triangle, Schwester Selma and The Precious Legacy. Yoninah, who enjoyed photography, was also active on Commons, where she contributed several images related to Jewish holidays and themes, along with photos of people and places in Jerusalem.

She became the soul of DYK. Yoninah assembled diverse and interesting sets of DYK "hooks", brought her knowledge of a wide array of topics to the project, and always put our readers' interests at the forefront of her work. She contributed hundreds of articles to DYK; among her last was Psalm 148, written in collaboration. She added Hebrew text and facts about use in Judaism to almost sixty of the Psalms. She was known as someone who could find high-quality, visually intriguing images to use for DYK. As one editor noted, it's not an overstatement to say that "Yoninah has touched the lives of almost every English-speaking person in the world with access to the internet—not primarily because of the articles she wrote, but the huge positive effect she had in our community."

Her death was announced to the community at Wikipedia talk:Deceased Wikipedians on 17 March 2021, and confirmed privately by various editors. However, out of respect for Yoninah's privacy, additional information about her real-life identity and her death have since been suppressed. We never knew what she looked like, or any other personal information that did not relate directly to DYK and Wikipedia. Yoninah's gift to the world was what Wikipedia was created for—a sharing of knowledge that renders invisible the boundaries of geography and politics.

Over 60 Wikipedians have left testimonials on her talk page, including:

• "Losing her not only left a pretty noticeable gap at DYK, but her death also makes me feel like a cherished friend has vanished."
• "Yoninah just quietly got on with the work and made a huge contribution to the project that will be truly missed."
• "Yoninah's contributions to Wikipedia were immense, and she was an exceptionally collaborative and helpful colleague."
• "תהי נשׁמתה צרורה בּצרור החיים." ("May her soul be bound up in the bond of life.")
• "Yoninah was a true guiding light in Wikipedia."
• "What a wonderful, generous spirit she held inside her earthly vessel."
• "You were always there for us on DYK, you were a rock, Yoninah."
• "She will be missed, and we will have big shoes to fill to continue her work."
• "Her commitment to the tidiness of the DYK section was magnificent."
• "Yoninah was a god-send when it came to images. Terrific lady, she was."
• "נר ה' נשמת אדם" ("The spirit of a woman is the candle of the Lord.")
• "The DYK community will feel less without Yoninah."
• "A true Wikipedian, the likes of which I'd never seen before on Wikipedia."
• "What a shattering loss. How tremendously valued she was in life."

Yoninah was beloved by many and will be remembered. May her memory be a blessing.

Rocco Pier Luigi was a pillar of the Italian Wikipedia; an extremely important user and administrator, he joined the project in 2005 following his passion for manga and anime. However, his wise mind brought him to care about nearly every corner of the wiki. He became a reference point for his gentle yet firm approach to users and content; a true example of administratorship. Moroboshi died at 54 of a sudden heart attack, which put an end to his lifelong illness.

The Italian Wikipedia is astonished. Rocco Pier Luigi's memory will always stay with us as a model and example. We will remember his kindness and we will keep on loving him, grateful for each and every one of his 16 years of edits. For each and every one of his exquisite words.

Ciao, Moroboshi

Sarah died in early May 2021 after a long illness. Her first edit was in November 2004, her last on 18 April 2021. An administrator since 2005, Sarah made a total of over 170,000 edits with another 4,500 edits at Commons.

Sarah was a major contributor to many featured and good articles listed here. Often these articles were on notoriously difficult subjects, such as Female genital mutilation, the Killing of Muhammad al-Durrah and Night. She created many Did you know? entries, and she was instrumental in the development of several policies and guidelines that are considered today to be some of Wikipedia's most fundamental principles, such as biographies of living persons, no original research, verifiability, and conflict of interest.

In 2006 she proposed ^[1] the Attribution policy ^[2] to replace Wikipedia:Verifiability and Wikipedia:No original research. Her first post to the mailing list ^[3] demonstrated a long-standing interest in such things. The name "verifiability" had not been the only name for the original policy; Jimmy Wales had called it "confirmability" in 2003, ^[4] for example. Both names had, and still have, the problem that people confuse "verified" with "verifiable" (and "confirmed" with "confirmable"). SlimVirgin wanted to address this problem with "attribution". ^[2] Within 2 days, the proposal had generated 214 kilobytes of discussion. ^[5]

In 2013, she founded the gender gap task force (GGTF), and in 2015 she wrote the essay Writing about women.

The references section is herewith in her honour.

At the start of 2020, SV was honored with the Editor of the Week Award. These are the words of User:Sj in his nomination. They speak to her greatness and the effect she had on WP:

"Our first editor of the new year is User:SlimVirgin, a 15 year veteran well known to many. She is one of WP's most respected editors; built on her integrity and dedication to building an encyclopedia that we can all be proud of. She is strong while wielding a steady collaborative persona. Her high quality contributions are related to multiple important topics and intersect with multiple WikiProjects. She highlights COI issues and calmly combats paid-editing on Wikipedia's top articles. She helps articles evolve into interesting and informative reading for our readers bringing free, complete, accurate, up-to-date health information to the public. She is a rare bright star among the sleeping throngs. The Wikipedia community appreciates her important efforts at quality improvement on this site at such a high level."

Comments at that time: 15 year veteran, known by many, respected by all. Wields a steady collaborative persona. Highlights COI issues and calmly combats paid-editing on Wikipedia's top articles. A rare bright star among the sleeping throngs. Improves WP at a high level. One of the top five or ten all time best WP editors ever. Few editors are able to be so hard-nosed when need be and yet so able to use a softer stance, what some may term "feminine" attitude, when that is required. Without SV Wikipedia would not be what it is today.

SV was also honored with the Precious award in 2017. In the kind words of Gerda Arendt:

"Thank you for quality articles such as Ezra Pound, Female genital mutilation and Night, performed in collaboration, for defense against self-promotion, for clarifying and amending, - you are an awesome Wikipedian!".

Andrew Cooper, who edited as GuillaumeTell, died in June 2021. He was an active editor from 2005 to 2015, especially in the areas of opera, architecture, and York.

• That he trained to great profit at Oxford under perhaps the greatest literary critic in English of the post-war era, Christopher Ricks, showed in all of his contributions to Wikipedia, Sit terra tibi levis, dear fellow Nishidani ( talk) 14:36, 11 October 2021 (UTC) reply
• I am very sorry to read this. GuillaumeTell helped me greatly with the first FA I worked on, William Burges, and his deep knowledge of architecture, and of Wikipedia processes, was of huge assistance. We interacted sporadically thereafter and I noticed and regretted his diminishing involvement. Another considerable loss, among an increasing number, to our collective effort.

• I will miss his collegial advice. It was GT who first suggested to me to write articles about Sidney Jones (composer) and Ivan Caryll. He was astonished that such famous composers had only stubs. This led me down the rabbit hole of Edwardian musical comedy, from which I did not emerge until I had added hundreds of new articles about composers, librettists, lyricists, actors and musicals, from 1890 to 1925. -- Ssilvers ( talk) 21:38, 11 October 2021 (UTC) reply

He touched many people here with his helpfulness, intellect and sense of humor and he will be sorely missed. He passed away on October 30, 2021. His death was reported by his nephew on his talk page. [2] Rest in peace.
