New light on William Maclure

Summary

The recent publication of twenty European travel journals originally written in the nineteenth century by William Maclure, the sometime ‘father of American geology’, has entailed major revisions in our understanding of their author. In the present essay I review geological portions of all twenty journals, integrating their contents with Maclure's already known but never before comprehensively discussed publications, which now appear in a new perspective. I then suggest a more adequate evaluation of Maclure's significance within a considerably revised schematization of the history of early American geology.
