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."
Pietro Roveri was a Brazilian editor of Wikipedia and Wikiversity, heavily involved in the formation of the Brazilian chapter. He did his master thesis on the dynamics of the Portuguese Wikipedia.

Tron Øgrim, a Norwegian Wikimedian, journalist, and author, died on May 23, 2007. He was 59 years old. Tron was one of the most influential persons in Norway's Marxist-Leninist movement in the sixties and seventies. He was one of the founders of the Workers' Communist Party, a party which strongly advocated the Chinese branch of communism. Tron was also central in the founding of the newspaper Klassekampen and the publishing house Oktober. Tron became a journalist after leaving politics in the eighties, having a technology column in the Norwegian edition of PC World. Tron became a Wikipedian in December 2005, when libelous statements about a colleague appeared in a Norwegian (bokmål) Wikipedia article. Tron continued as a Wikipedia editor after the issue was resolved, writing about constructed languages through most of 2006. In the fall of 2006, his focus changed to Nepal generally and the history of communism in Nepal specifically (see Nepals kommunistiske parti (maoistisk) for an example of one of his articles.) Tron was known in the Norwegian wikicommunity for writing very long articles about somewhat obscure topics. Tron also cared much about smaller wikis and their progress. He was routinely posting messages about milestones at the Norwegian Village Pump, as well as participating on the Wikimedia News announcements page. Tron was extremely important for the Norwegian wiki movement, and he was often interviewed by the press about Wikipedia. He gave a lecture about Wikipedia when Wikipedia's founder Jimbo Wales visited Norway in May 2006. More info on him is available at Tron Øgrim and Wikipedia:Wikipedia_Signpost/2007-05-28/Wikipedian_death.
