Crossing 
KOOKIE (‘60’s) with “
Heyday’s” (‘30’s) PEAK, 
TATI (‘50’s), and

Boardwalk Empire, its main character named Enoch (who for some reason is called Nucky not Nocky).]   

Really?
TISCH --- a name on a school building?
SVEN 
Hedin --- explorer from a different country a century ago?  SVEN clogs or even SVEN Nykvist would be a bit more sporting.
