The French botanist Théodore Leschenault (1773-1826) travelled with Nicolas Baudin's voyage of discovery to Australia in the years 1800 to 1803: his journal and letters vividly record his impressions of the plant life and animals he encountered, along with dramatic and unsettling meetings with Indigenous peoples. Shaped as much by Enlightenment ideas as by his painful experience of the French Revolution, Leschenault weaves through his travelogue reflections on topics ranging from slavery and colonialism to plant classification and environmental damage. Long thought lost, Leschenault's original manuscript journal was rediscovered only in 2016. The French Collector offers the first complete English translation of this journal, including two previously unknown chapters on his experiences in Le Havre, Tenerife and Mauritius. This edition also provides extensive explanatory notes and an introduction which details Leschenault's early life in Burgundy and imprisonment during the Revolution and sets his activities against the backdrop of French science and exploration in the period.
