Although this maxim is associated with Wiesenthal (e.g. "Honoring Simon Wiesenthal", Congressional Record—House, Vol. 151, Pt. 15, 21 September 2005, p. 20804), he did not originate the quote, which appears in the context of the labor movement in the 19th century (e.g. Alexander Spencer, "Maintain Your Union", The Typographical Journal, Vol. 10, No. 7, 1 April 1897, p. 266).
