43843 Cleynaerts           Discovered 1993 July 12 by E. W. Elst at the European Southern Observatory.
Nicolas Cleynaerts (Clenardus, 1495-1542) was a Flemish humanist who promoted tolerance between the nations and a grammarian who wrote manuals to study Greek and Hebrew. Desiring to bring Islam and Christianity closer together, he got into conflict with the Spanish and Portuguese authorities.
