Louis Pouzin is the French computer scientist who made the key technical step in data networking between the ideas of the ARPANET and those of the later Internet: moving reliability mechanisms into the hosts, allowing the network (and its constituent packet switches) to be unreliable - and thereby simpler and faster.

The network that he and his team built, using this new approach, CYCLADES, laid the technical groundwork for the Internet.
