Siméon-François Berneux

Siméon-François Berneux was a French Catholic missionary to Asia, and a member of the Paris Foreign Missions Society who was canonized as a saint. Berneux was executed in the anti-Christian purges at Saenamteo, Seoul, Korea, in 1866. His death provoked the French campaign against Korea the same year, which led to Korea reinforcing its ongoing policy of isolationism.
