Imagine you are searching your name and up comes the Google knowledge graph with your box at the top right. Then you read what Google has to say about you and it says you have died several years ago. How is that possible, you are not dead.
That is the case for Madhav Prasad Ghimire, a well respected poet in Nepali. He is actually around 94 years of old and just was interviewed by a local newspaper in the area.
But when you Google Madhav Prasad Ghimire, Google will tell you he is dead.

See, according to Google, he died on September 14, 1959, almost 53 years ago. In fact, it seems Google also has the wrong birth date. He was born on October 22, 1919 not November 12, 1909.
What is going on here? Two possible cases:
(1) Google is referencing a different Madhav Prasad Ghimire but I have no idea which one.
(2) Google has buggy factual data for Madhav Prasad Ghimire and possibly others.
Google responded to the complaint in the Google Web Search Help forums saying:
Thanks for reporting, Manjeet Dhakal and Shannon for the investigative work! I am looking into this for you.Manjeet, we really appreciate this feedback as it helps make our information as accurate and up to date as possible.

Update: As pointed out on Google+ by Pe lagic, Wikipedia had his death on an older version of the page.

Sounds like it's time to file some amended tax returns referencing Google.

Maybe Wikipedia placed this in their articles as a honeypot for Google to fall into, in a similar way to what Google did with their search results when Bing was scraping them :-)

Um, so unsurprisingly Google had it wrong as wikipedia had it wrong. The 'knowledge graph' is just wikipedia in the serps. If I was wikipedia, I'd seriously consider banning Googlebot. I mean do the volunteer writers on wikipedia do it for Google to make money out of what they write?

My point still stands though. It's not made clear to contributors that they are contributing to Google as well. Didn't know that Google pays all their server costs though, that's an interesting one. Explains why Wiki are happy for them to use their data so much

Not sure that is true. Google "offered" to pay something towards hosting. That is all, as far as I can tell from research. Wikipedia take donations to pay for hosting costs, hence their yearly annoyance campaign.
