English physicist and inventor.
Sir Charles Wheatstone was an english scientist and inventor of many scientific breakthroughs of the Victorian era, including the english concertina, the stereoscope (a device for displaying three-dimensional images), and the Playfair cipher (an encryption technique). However, Wheatstone is best known for his contributions in the development of the Wheatstone bridge, originally invented by Samuel Hunter Christie, which is used to measure an unknown electrical resistance, and as a major figure in the development of telegraphy. Samuel Morse invented the Morse Telegraph that was adopted as the standard in telegraphy. However, he invented and contributed in several fields of science, including photography, electrical generators, encryption, and acoustics and music.

Enchanted Lyre or Aconcryptophone was not a real instrument, it was a sounding box disguised as a lyre that hung from the ceiling by a steel rod, and emitted the sounds of several instruments: piano, harp, and dulcimer. However, the steel rod conveyed the vibrations of the music from real instruments which were played out of view by real musicians.
