James M. Heilman (born 1979 or 1980) is a Canadian emergency physician, Wikipedian, and advocate for the improvement of Wikipedia's health-related content.

[22] Later that year, Heilman co-authored a version of the Wikipedia article for dengue fever in the peer-reviewed journal Open Medicine.

[23] Heilman also worked on a study with Microsoft which found that in the three countries where the 2013–2016 Ebola outbreak had the largest impact, Wikipedia was the most popular source for information about the disease.

[24] In 2015, Heilman and Andrew West published a study which found that the number of Wikipedia editors who focused on editing medical articles decreased by 40 percent from 2008 to 2013.

[27] Since the beginning of his activity as a contributor to medicine-related Wikipedia articles in 2008, Heilman has been promoting the improvement of medical content by encouraging fellow physicians to take part.

[1] He became interested in editing Wikipedia on a slow night shift, when he looked up the article on obesity and found that it contained many errors.

[29][30][31] The Wiki Project Med Foundation has started a collaboration with the University of California, San Francisco as a recruit for scientifically literate editors, by giving students college credit for improving medicine-related Wikipedia pages.

[32] In 2014, the Wiki Project Med Foundation also partnered with the Cochrane Collaboration, with the goal of improving the reliability and accuracy of information on Wikipedia.

"[33] Heilman spoke at Wikimania 2014, where he said that 93 percent of medical students use Wikipedia, and argued that "fixing the internet" is now a critical task for anyone who cares about healthcare.

[38] In 2014, he told the Cranbrook Daily Townsman that with respect to Wikipedia's coverage of Ebola, "The big thing is emphasizing what we know, making sure that minor concerns don’t get blown out of proportion.

"[20][42] In an interview with The New York Times, Heilman stated that he added the entire set because a debate about a single image seemed absurd and psychologists' fears were unfounded.

[43] In 2012, Heilman noticed that the book Understanding and Management of Special Child in Pediatric Dentistry, published by Jaypee Brothers, contained a long passage about HIV that was plagiarized from Wikipedia's article on the subject.

[25] Christian Purdy, an Oxford University Press spokesperson, acknowledged that some of the text in the textbook had been copied but described it as an "inadvertent omission of an appropriate attribution" rather than plagiarism.

[9] In December 2015, the board removed Heilman from his position as a Trustee,[10][48] a decision that generated substantial controversy amongst members of the Wikipedia community.
