Conradus Leemans (24 April 1809 – 14 October 1893) was a Dutch Egyptologist.
[1] Leemans enrolled at Leiden University in 1826 to study theology, but changed to archaeology in 1828 apparently after meeting with Caspar Reuvens.
Leemans organised the first public display of collections of acquisitions made by Reuvens, compiled a catalogue of Egyptian objects (Catalogue raisonnée, 1840), and edited the serial publication of the Monumens égyptiens, this being a lithographic account detailing the collection.
[2] Leemans studied the Leiden papyrus while Director of the museum, completing the work begun by Reuvens on this.
Either the paper or glue used to affix the paper has degraded causing some of the writing to become obscured, and Leemans's addition is thought to be fixed permanently, since otherwise too great damage would be done to the artifact in its removal.
