Frank Shailor- don't know if he invented anything else.
Charles Strite was with his wife one day shopping and the saw a toaster. It wasn't a toaster like you and I are used to, it was a toaster where you had to flip the bread by hand. His wife said " Wouldn't it be easier to have the bread turned automatically?" This lead Charles to make the Automatic toaster. Charles made an improvement to the automatic toaster by creating the first ever electric pop-up toaster.

NO Laszlo Biro did not invent anything else besides the ball point pen. He invented the ball point pen in 1938.
Yes. He also invented the first typewriter with a keyboard in 1821.
Presumably from an enquiring mind, more than anything else. Whether he can be said to have "invented" or "discovered" them, is another matter.
