Charles Batchelor was a master mechanic and draftsman who associated closely with Edison on many crucial projects, like the phonograph, telephone, electric lighting etc. Also, it was he who made the precise drawings which Kruesi turned into models.
Manchester-born Batchelor became one of Edison’s most valued colleagues during the 1870’s and 1880’s. In 1873, Edison designated him as the ‘chief experimental assistant’.
