Joseph Henry

摘要

Joseph Henry lived and worked approximately at the same time as Michael Faraday (1791 -1867, RadioUser, January 2019:46). However, it seems that Henry is, by and large, the lesser-known figure in the history of radio. Like Faraday, Henry was working against the background of the big philosophical debates and the milestone electromagnetic discoveries of the time. Joseph Henry was a 'natural philosopher' - we would refer to him as a 'scientist' today - an avid experimenter, and gifted lecturer, educator of the young, and a science-communicator.
