Who is Peter Nivio Zarlenga?

I met Peter back on the 80´s due to a common friend we have in Capistrano, Ca. Without knowing anything on him,, was amaze when he start talking. Remembered as one of my most fascinating experiences to be in front of a genius, listining to him for almost 2 hours. I hope he still remembers me and wish could know how to contact him. Diego F.
