Sherry Rowland was a post-doc at Princeton when I was there.  His work was in

the laboratory, where he found that some Freons catylzed the decomposition of

ozone.  This, of course, could be a neat thing to have happen at ground level in

Los Angeles.   The problem was that Freon is quite inert, and stays around for a

long time, allowing it to diffuse to high altitudes.  It was rather later that

the search for consequences of the observed catalyst behavior led to the

identification of the ozone hole.  Previous comments to Radsafe seem to imply

that it was the correlation  between ozone in the atmosphere and Freon release

alone that prompted the Nobel Prize.
