  Since de Broglie's pilot wave theory was revived by David Bohm in the 1950's,
the overwhelming majority of researchers involved in the field have focused on
what is nowadays called de Broglie-Bohm dynamics and de Broglie's original
double solution program was gradually forgotten. As a result, several of the
key concepts in the theory are still rather vague and ill-understood. In the
light of the progress achieved over the course of the 90 years that have passed
since de Broglie's presentation of his ideas at the Solvay conference of 1927,
we reconsider in the present paper the status of the double solution program.
More than a somewhat dusty archaeological piece of history of science, we
believe it should be considered as a legitimate attempt to reconcile quantum
theory with realism.
