The several Roebling structires which are still extant are  
magnificent: Brooklyn Bridge, Cincy-Covington Bridge, et. al.

The man who was officially, and contractually credited with the  
design of the Golden Gate Bridge was not its actual designer.  
Roebling provided the cables on that one, so it is in part inspired  
by Roebling.

I would guess that Roebling provided the cables on contemporaries of  
those bridges, too, including the Oakland-San Francisco Bay Bridge  
(western portion, only) and the Tacoma Narrows bridge (which failed  
shortly after it was completed).

The GGB and the TNB include concepts which are attributed to Leon  
Moisseiff.

Fortunately, after the TNB failed catastrophically, the GGB had its  
deck strengthened, and stiffened, twice, and it still stands today,  
very likely the most beautiful bridge in the World, but, alas, no  
longer the longest.
