Harrison vs Marconi: who really conquered distance?

I gave sailors their longitude with a clock that kept true time through storms and heat, and no man drowned lost again for want of it.

And when the Titanic sank, it was my wireless, not your ticking, that pulled seven hundred souls from the sea.
