Ok, here's the info that I know: 

"In the spring of 1963, an undergraduate advertising major at UCLA
submitted, in fulfilment of a routine course assignment, as ad
campaign for Honda. Its theme: You Meet the Nicest People on a Honda."

This campaign became very famous, and is generally regarded as one of
the most famous in American history.  My problem is that I can't
figure out FOR THE LIFE OF ME what that student's name was! I want to
use his story as an anecdote in a speech.

My Question... "What was the UCLA student's name who coined the phrase
'you meet the nicest people on a honda'"?

in a google search, the following was found:
campaign was developed by Grey Advertising

concept was created by Jack McCormack

john mckay says the UCLA story is false:
