I might be confused with the film's interpretation, but I think Saruman was the first to devise gunpowder. He probably didn't have much time to think on how he might better use it. He probably didn't have much powder to spare for experimenting, as he only had one bomb for Helms Deep. There's a chance Sauron or Morgoth before him knew a bit or two, but I think a cannon would be stretching things a bit.
