1855                289 Broadway, New York, New York.

Professor Buffer was recorded in the New York Daily Tribune (New York, New York) on May 24, 1855 in an advertisement.  Irish Artists—25 Cent Daguerreotypes.—Prof. Buffer of Dublin has arrived with his celebrated company of 25 Irish picture-makers, and has taken bunks at 289 Broadway for the season.            Buffer & Co.

289 Broadway is the studio address for Silas A. Holmes.  This is the only mention of Professor Buffer in any of the New York Newspapers I have found to date.   This is not the first advertisement that Holmes advertises that he has 20 or more artists working for him.  Holmes continues to advertise his gallery, one more time in May, six times in June, July three times and two in August.  For the next four month he advertises eight time each month.  For more information see a piece I posted on Silas A. Holmes on January 20, 2018.
