That is not late at all! I need at least 100 answers (of course, I posted to some other forums, but it's going very slow). So your answer is of GREAT help!
Thank you very much, especially for such various ideas about who the Pioneers are/were:

I think of things like the Oregon Trail or the California gold rush. However, in today's terms I think of pioneers such as NASA (going to space and exploring) but I also think of business pioneers (such as Facebook...as crazy as that may sound).
