Back in the early 80's, one of my best friends, Jim Kessler (VP and General manager of Sprockets Systems) needed a design for the THX logo. We were out having a cocktail so I took a cocktail napkin and pretty much drew out the logo in one attempt. I started with a T with a long right horizontal cross and place the HX underneath with an underline matching cross somewhat like a Roman numeral. Then I widely spaced small letters Lucasfilm Sound System above and below. All in all it took less than five minutes to sketch it out. So there you have it, that’s how it originated.
