The above quote is ascribed to Stephen Grellet (see, below), but this is disputed by some people.
Stephen Grellet (2 November 1773 – 16 November 1855) was a prominent Quaker missionary. Born Etienne de Grellet du Mabillier, son to a Counsellor of King Louis XVI, at 17, he entered the King’s Body-Guard.
During The French Revolution of 1792, he was sentenced to be executed, but escaped and eventually fled Europe to The United States in 1795, where, in 1796, he joined The Religious Society of Friends (The Quakers).
