Of those sponsoring this conference, we know he met and talked to J. A. Seiss, L. C. Baker, G. C. Needham (Pretty much a bastard in my view.), D. W. Whittle (ditto), H. L. Hastings, W. V. Feltwell, Josiah Litch. We suspect he met others of the sponsors, but can't prove he did.
Of those attending we know he met Jenny Smith, an author. (Interesting story there.)
