Joseph Duchesne

Joseph Duchesne or du Chesne (Quercetan, Latin Josephus Quercetanus) (c. 1544, Lectoure – 1609) was a French physician.

During the 1570s at Lyon, he married Anne Trie[2] the granddaughter of Guillaume Budé, and became a Calvinist convert.

He left Lyon in 1580 for Kassel in Hesse, and moved on to Geneva, where in 1584 he received citizenship.

Duchesne was elected to the Council of Two Hundred in 1587, and undertook diplomatic missions to Bern, Basel, Schaffhausen and Zürich in the years 1589 to 1596.

In 1601 Nicolas Brûlart de Sillery gave him a mission as envoy to the Swiss cantons.
