Built for people, by people
Wikipedia is built by nearly 250,000 volunteers from all kinds of backgrounds. They edit articles, check facts, fix code, and help make the internet’s knowledge better. Meet some of them.
Taufik Rosman
Malaysia
The 2023 Wikimedian of the Year, Taufik has been editing since he was 8 years old. He has expanded the Malay Wiktionary with nearly 11,000 changes. “Each of our contributions matters greatly,” Taufik says.
Siobhan Leachman
New Zealand
Siobhan expands English Wikipedia with knowledge about notable women in biodiversity and natural history. Thanks to her, Wikipedia has information about all of New Zealand’s 1,800 endemic moth species.
Armine Aghayan-Flisch
Switzerland
Writing a Wikipedia article each day for a hundred straight days is a feat. Arminé has done it thirteen times on the Armenian Wikipedia, while also uploading over 20,000 open-licensed images.
Donatien Kangah
Côte d’Ivoire
The most visible part of Donatien’s French Wikipedia work is in the site’s coverage of African football. But behind the scenes, Danatien also runs an organization that expands Wikipedia’s knowledge of Côte d’Ivoire.
Wilfredo Rodríguez
Canada
Prolific photographer Wilfredo has shared over 50,000 images with Wikimedia projects. Many come from his home country of Venezuela to preserve its beauty for the world’s benefit.
Ellie Méndez
El Salvador
Ellie has collaborated with multiple El Salvadorean cultural institutions to expand Wikipedia’s coverage of women’s sports in Spanish and train people in updating the site.
Mónica Paola Bonilla-Parra
Colombia
As the head of Wikimedia Colombia, Mónica works to encourage people to share knowledge on Wikipedia. “There are no limits to participating and contributing,” she says. “If you don’t do it, who will?”
Alberto Leoncio
Brazil
Most work on Wikipedia happens behind the scenes and is performed by volunteers like Alberto. The time Alberto spends on technical tasks makes life easier for all other Portuguese Wikipedia editors.
Alaa Najjar
MENA region
Alaa’s nearly 600,000 edits on Wikimedia projects have expanded the sites’ knowledge of medicine, anatomy, and biology. In thanks, he received the prestigious 2021 Wikimedian of the Year award.
Nkem Osuigwe
Nigeria
Nkem is a connector: she brings volunteer Wikimedia editors and librarians from Africa together. Her work in organizing the first African Librarians Week generated nearly 28,000 improvements on Wikipedia.
Ananya Mondal
India
A clinical nutritionist by trade, Ananya singlehandedly spearheaded an initiative to upload more images of butterflies onto Wikimedia projects. She’s since inspired people to upload over 15,000 new photos.
Netha Hussain
Sweden
Netha uses her expertise as a doctor to ensure medical content on Wikipedia is accurate, well-sourced, and easily understood—from COVID-19 content during the pandemic to documenting misinformation around women’s health.
Rosie Stephenson-Goodknight
United States
Rosie co-founded the Women in Red project, which is spearheading an effort to increase Wikipedia’s biographies about women in English. So far, they’ve added over 200,000 articles.
Andrew Lih
United States
Long-time Wikipedian Andrew wrote The Wikipedia Revolution, a foundational book on the history of Wikipedia. Over the last two decades, he’s made over 760,000 improvements across Wikimedia projects.
