The history of submarines is one of men wanting to discover new frontiers through perseverance and grit, greed, luck – and tragedy. This first episode takes us all the way back to antiquity, to the days of Aristotle and Herodotus. Then we will see how the first submersibles first surface in the imagination and fantasies of inventors and dreamers, and to then be made a reality by men like Cornelis Drebbel and David Bushnell. So get to that listening station, don those headphones and dive in.
