The mahogany table holds two identical lanterns which fit one above
the other. The lower lantern has a hinged support to carry the one on
top. The lower bears the signature on an oval brass plaque. Each lantern
has a tinplate cowl, and both have lenses focused by rackwork. Over the
lens holders fit shutters for projecting dissolving views, i.e., as one
opens the other closes. Purchased in 1861 for Dfl. 723, including
accessories and a collection of demonstration slides. Double lanterns
and dissolving views were devised in 1807 by Henry Langdon Childe
(1781-1874); see DNB. Chadwick (1878).
Andreas Kriiss (1791-1848) founded his own workshop in
1844, and the widow gave it to the sons, Edmund and William, in
1851. Trading continued into the twentieth century; see Brachner
(1985), 143.
