The magic lantern,  is an early type of  image projector employing pictures painted, printed or produced photograpghically on transparent plates (usually made of glass), one or more lenses , and a light source. It was mostly developed in the 17th century and commonly used for entertainment purposes. It was increasingly applied to educational purposes during the 19th century. The magic lantern was in wide use from the 18th century until the mid-20th century, when it was superseded by a compact version that could hold many 35 mm photographic slides: the slide projector.
The Tampa Bay Hotel was built by railroad magnate Henry B. Plant between 1888 and 1891. The construction cost over 3 million dollars. It was considered the premier hotel of the eight that Mr. Plant built to anchor his rail line. The hotel itself covers 6 acres and is a quarter-mile long. It was equipped with the first elevator ever installed in Florida.The elevator is still working today, making it one of the oldest continually operational elevators in the nation. The 511 rooms and suites were the first in Florida to have electric lights and telephones. Most rooms also included private bathrooms, complete with a full-size tub. The price for a room ranged from $5.00 to $15.00 a night at a time when the average hotel in Tampa charged $1.25 to $2.00. The poured concrete and steel reinforced structure of the building was advertised as fireproof. It is now home to the University of Tampa.
