It was there in older versions of the article. See for example: https://en.wikipedia.org/w/index.php?title=Fletcher%27s_checksum&oldid=730327006 > Second, this should have been high-lighted in your submission somehow. Definitely. All code has an original author who deserves credit. And if you cannot find the original author, then there is always a risk than someone along the line stole the code... Maybe long before it ended up in Wikipedia. But that doesn't matter. Doesn't seem worth the risk for a simple checksum algorithm which probably has lots of GPL implementations.
