Dr. Ed David. 10/13/79. Exxon Symposium. Thank you for the privilege of attending a most useful (and generous!) presentation Many of my perspectives in a variety of fields were broadened in a short time. Your reply to my question about environmental analysis was exactly what I anticipated: my concern was that Swalb had passed it by; and I wanted Exxon's good example to be more manifest to others Peter Lucchesi was good enough to fill me in on the organizational and historical background If you have the time plainly there would be merit in our getting together again -- perhaps all 3 of us. May I call you in a few days to see if a mutually convenient time can be found? Sincerely, Joshua. also OK'd 12/3 [ . . . ]
