I post the following response to my last statement from Ed Folsom, Editor of the WALT WHITMAN QUARTERLY REVIEW: William Sloane Kennedy in REMINISCENCES (p. 26) offers this very straightforward list of attendees: "James Russell Lowell, John Burroughs, and Professor Charles Eliot Norton, occupied the box at the poet's right. Mr. E. C. Stedman and his family were seated in the opposite box. Others present were Samuel L. Clemens, H. C. Bunner, Frank Stockton, Moncure D. Conway, Joel Benton, Colonel John Hay, Edward Eggleston, Andrew Carnegie, Augustus St. Gaudens, Mrs. Frances Hodgson Burnett, Richard Watson Gilder, Mrs. Mary Mapes Dodge, President Gilman of Johns Hopkins' University, Professor James A. Harrison, Mrs. M. G. Van Rensselaer, and Miss Jeanette Gilder." Kennedy is generally a reliable source, and the fact that he mentions Clemens first in his list suggests the importance he placed on his attendance at the event. The NY Times account lists some of these people, but not nearly all of them. It's a much briefer list. Just the day before, they had devoted space to Clemens in their long account of the festivities surrounding Daly's production of Taming of the Shrew. So, on the one hand, it's odd they wouldn't have mentioned Clemens in the Whitman account; on the other, their society editor may have decided to spread the attention around by mentioning some different names.
