characters alter egos

I thought the the last half hour episode was awesome. Especially when they were in the apartment and all there alter egos met.

    Art Vandelay
    Penny Packer
    and........
    What was Jerry's rich alternate ego name again?
    was it  ____ Von ____ something like that

I can't believe i don't remember
