This is both a memorial and listing of Wikimedia editors who have passed away. Naturally, this list is largely incomplete, and any additions are very welcome and appreciated. If you are aware of an undocumented deceased editor, please add them to the list, along with a short biography if possible. Accounts whose owners are known to be deceased should be globally locked.
The purpose of this list is to provide a reminder of those who have passed on and to remember the contributions these editors made to the success of Wikipedia. Please do not add people to this list who were never an integral part of the community. People in this list should have made at least several hundred edits or be known for substantial contributions to certain articles. Do not add people unless you have confirmed information that they are deceased.

|Babug (G. Balachandran -- Malayalam)||Malayalam Wikipedia editor. Eulogy by fellow Malayalam Wikipedian Viswa Prabha follows:
One of our stalwarts at ml Wikimedia community, Babug expired yesterday night.
Despite having paralyzed due to a severe stroke and severely affected by several subsequent health problems, he was guided to Wikipedia by his son, Dr. Ajay, another prominent Malayalam Wikipedian, as a possible remedy to escape perpetual loneliness.
His real world name was G. Balachandran. He was born on 14th October 1938 in a small village off North Parur, Ernakulam District, Kerala, the southwesternmost state of India. He joined the Armed Forces Engineering College and then continued to serve the Indian Armed forces for long many years.
He started contributing to Wikimedia, particularly to Malayalam Wikipedia, in the year 2008.
His initial contributions to Malayalam Wikipedia were based upon a pulp-converted digital Encyclopedia, released by the Government through GFDL licence then. He continued to create even more full-featured articles on his own, later. By 2014 October 18 - the day he edited last in Wikipedia- he had 1935 full-blown articles initiated and expanded by himself in ml.wikipedia.org. Besides, he also contributed more than 350 images to Wikimedia commons and a handsome amount of contributions to Wikisource, Wikidata and Wiktionary.
He always attributed his renewed energy and life's aspirations to the Wikimedia mission, for having returned to a meaningful life after a 20-year long and frustrating solitude while constrained to an immobile chair. Ever since 2008, he stood up and started walking and moving around. His was an extreme example for us in Malayalam WP to showcase how Wikipedia can change lives.
In almost all our Wikipedia Outreach sessions, we utilized this great example to motivate and excite the newcomers to WP.
Tory Read mentioned about BabuG thus, in a review on the state of Indian Wikimedia Communities, in 2011:
For us in Malayalam Wikipedia, today is a black day, for having lost a great beacon on our voyage to ultimate openness and freedom in knowledge and wisdom.
Yet, we feel, BabuG has made his life stamped immortal for ever and has shown us the pathway we should follow in continuing our humble contributions to the ultimate cause of mankind.

He contributed during less than 13 months, but translated hundreds of articles from English to Esperanto. He was also active in the English and the Tigrinya Wikipedias (as en:Oryanw and ti:Oryanw).
Bill was multilingual speaking English, Tigrinya, Dutch, Spanish, Turkish, etc. He also learned a multitude of computer languages. He spent countless hours translating articles from English into Esperanto on Wikipedia.
Josephine wrote : "He worked for years on a Tigrinya/English dictionary. His good friend Marco says that he feels Bill was probably the premier expert on Tigrinya in the United States. He was always learning. He taught himself anything he was interested in. His interests included science, history and languages. I used to teach science and whenever he would call me and ask if I had heard about something scientific, I would groan because I knew he would ask me about something I didn’t yet know or about which I knew less than he did. He belonged to book clubs and would go whenever his body would allow him to.
When he discovered Wikipedia, he was excited to realize he could contribute so much. His hands were painful and he had lost a lot of his small motor skills but he painstakingly would type out his translated articles. He trained himself to use his left hand on the mouse because the right hand didn’t work so well. His Wikipedia contributions and his Tigrinya dictionary were reasons to keep fighting because he felt he was making a difference."
