context_page_description: Below is a list of Edison patents. Thomas Edison was an inventor who accumulated 512 patents worldwide for his inventions. 1,093 of Edison's patents were in the United States, but other patents were approved in countries around the globe.
context_section_description: The first hundred patents mainly deal with the telegraph system. John Kruesi was the shop manager beginning in 1872. Kruesi built models, instruments, and apparatus for Edison's work.
  John Ott worked with Edison throughout his career. Ott was Edison's main model and instrument maker. Charles Batchelor was a superintendent for Edison toward the end of this series of patents.
