This question is very hard for me to answer especially as I know a lot about history. I know many say Johannes Gutenberg because he invented the printing-press which caused books to be more widely available instead to just a few thus educating countless generations. I typically don't care much for inventors historically as I believe many of the vast majority of inventions would have came along eventually if that person had never been born. I don't think one man can be considered the most important in history.
Who do you think is the most important individual in history?
