Alexander Graham Bell is well known for patenting the telephone in the United States. His work was driven by his desire to find solutions for the deaf. His research and development started the telecommunications industry that is common today and lead to the discovery of sounds from the Universe.
Bell Labs carried on that legacy and developed many technologies and devices. In a lecture by Honor Harger, the beginnings of radio astronomy are credited to Mr. Bell's assistant, Thomas Watson. In the early days, Watson listened to the noise produced on the telephone wires that were strung around the neighborhood. This noise is the subject of Ms. Harger's lecture.
