EveAnna: About Langevin...

I'm curious about something, from purely a history-geek perspective:

Is there any connection between the Langevin name on that line of Manley gear, and Paul Langevin, the French scientist who pioneered underwater sound transmission techniques (which were studied by British and American militaries for use in u-boat and submarine detection towards the end of World War I)?

Langevin was also an early pioneer of piezoelectric research, so I wondered if there was some kind of lineage.

Either way, perhaps this could spark a discussion of piezoelectrics.

Thanks!
