Abstract

Museums collect, preserve and interpret physical objects because they contain historical evidence that is sometimes difficult – if not impossible – to access through text and image-based research alone. In cases where original objects have been lost to history, reconstructions offer one way of reclaiming aspects of a past object’s design, use context and material culture. This article describes one such reconstruction project, which I recently undertook with collaborators at the Canada Science and Technology Museum in Ottawa. The goal of the project was to reconstruct Alexander Graham Bell and Clarence J Blake’s ear phonautograph: an 1874 curiosity that used an excised human middle ear to visually inscribe sound waves. Originally conceived of as a tool for deaf education, it became better known as the instrument that provided Bell with the technical insights he needed to develop and patent the telephone in 1876. This article consists of three parts. The first provides a historical background of the ear phonautograph and rationale for its reconstruction; the second offers a detailed description of the research and fabrication process; the third presents preliminary research findings that emerged through our experience building and operating the completed reconstruction.
