Jenny took a train trip to Cryptovnia. Upon deboarding, she was handed a leaflet by Hugo, the station agent. Printed on the leaflet was the following enigmatic diagram:

L E O S I A X W M J W     Word List:
O N E B A T T I S M T     DZURLBWMW
U J A A L W B E W K R     JMFYYI
V K M V S B G B T Z I     PCKSFQSX
H U S F E T L H E G K     SIAXWMJ
B E H Y Y R W O R A D     SPAVRAGZKMJ

I R D T H E E N I A N     ITGBHVUO
E H I D D E N O W P O     HFSW
R D S P C K S F Q S X

Hugo confiscated Jenny's passport and informed her that she would not be allowed to return home until she could provide the name of the famous cryptologist hidden within the diagram. In addition, her passport photo would be used as Hugo's personal screensaver unless she deciphered the listed words.

Won't you help Jenny recover her passport and obtain a trip back home by discovering the hidden name and finding the key to deciphering the word list?

That's right, Hugo.  There's more to it.  Finding Leone's name is the easy part.  The message following his name describes what to do next.  The title of this puzzle is a major hint to what encryption/decryption technique is being used.  The method, in fact, is historically associated with Leone himself.  An internet search engine might be a useful tool to anyone seriously interested in solving this.
