1850-1851       271 Main Street, Waldo Block, Worcester, Massachusetts.

Morse (partnership of Aldrich & Morse) was recorded in an advertisement that ran from January 1 to March 14, 1851 in the Worcester Daily Spy (Worcester, Massachusetts).  Now Is The Time, And Waldo Block is the Place.  In order to introduce our Types to the public, we shall sell them for a few days for fifty cents.  In the Best Cases for One Dollar, such as are sold for $1.50 at other rooms.  We intend to attract the public to our Rooms by making good Miniatures at fair prices, rather than by a display of Stained Glass, costly Mirrors, Tapestry Carpets, &c.  Beware of humbugs, and remember our Rooms are up only one flight of stairs, and that we have decidedly The Best Light in the City.  Aldrich & Morse.  Worcester. Nov. 2, 1850.

Morse is not listed in A Directory of Massachusetts Photographers, 1839-1900.  Craig’s Daguerreian Registry list the partnership as being active in Albany, New York in 1851-1852.
