What is vencent goghs full name?

Answer 1

Assuming you mean the painter, his name was Vincent Willem van Gogh.

By the way, "van" is not a middle name, his last name is "van Gogh," not just "Gogh". It's pretty common in some parts of Europe, especially the Netherlands, for a last name to have one (or more) spaces in it (the first parts, which are typically not capitalized, are usually prepositions meaning something like "from" or "of the"). When people with these names move to English-speaking countries, sometimes the various parts of the names are concatenated (and the entire last name is capitalized, e.g. "Vanderbilt") and sometimes not.
