1. Joseph Priestley (1732–1804), dissenting clergyman, discoverer of oxygen, political radical, and voluminous writer on theology and other subjects (
). This was the beginning of a long but not untroubled relationship, for Priestley fled from Birmingham to Pennsylvania in 1794 and his political views and utterances during JA's Presidency led to suggestions that he be deported under the Alien Act—suggestions which JA refused to act on (JA, Works
, 9:5–6, 13–14). There is an excellent brief account of their relationship in Haraszti, JA and the Prophets of Progress
, ch. 14, which includes JA's marginalia in his own copies of some of Priestley's theological writings.
