Trivial Tuesday

As I'm writing this I am still thinking of a trivia question for today.  My mind is totally and completely blank, but I'm hoping to come with something by the time I reach the end of this sentence.  Nope.  Maybe now.  Nope.  Give me a few minutes, talk amongst yourselves.  Ah, OK, I got one.

This man, ironically, is the inventor of dynamite.  Who is it?

OK, that's all I got and it will probably be answered in a matter of minutes of posting.  If it is, maybe I'll return with a new one.  Of course, there is another option...Discuss.  It's an experimental idea I came up with, so let me know what you think.
