Athanasius Kircher

Athanasius Kircher (1602–1680) was a German Jesuit scholar and polymath whose work spanned Egyptology, geology, music theory, optics, and acoustics, earning him a reputation as "the last man who knew everything." Based in Rome, he built an influential museum of curiosities and instruments at the Collegio Romano.

Kircher's inventions — including early megaphone and speaking-tube designs and the infamous cat piano — combined genuine inquiry with theatrical showmanship. Though many of his theories, including his decipherment of Egyptian hieroglyphs, were later disproven, his encyclopedic curiosity made him a touchstone for thinking about sound, media, and knowledge.
