- July 29, 1929 – JSA to A. M. Dudley (Pittsburgh)
Dear Mr. Dudley:
I have in mind for some time the desirability of you and I renewing our acquaintance and also talking over some of our problems in exchanging data, and I want to invite you to visit both our plant here and my camp at Lake George where the water is particularly inviting at this time.
Cordially yours,
JSApperson
