Starship Claude

There was a story-after apocalypse, a short story-where the surviving generations dug up old info and used it to get back to space-then they found a set of blueprints for a warp-driven starship-and built it. It was named Claude, after the chief scientist involved. Who wrote it-and what was the title?

 

Are you sure it's Claude?

I see you made a post a few months back and didn't get a result either.
