Moritz Eduard Pechuël-Loesche, (26 July 1840, Zöschen – 29 May 1913, Munich), was a German naturalist, geographer, ethnologist, painter, traveler, author, plant collector and Professor of Geography in Jena and Erlangen.
Eduard was the eldest son of Ferdinand Moritz Pechuël, an innkeeper and mill owner, and Wilhelmine Lösche.
Following a further period of study at Leipzig University, he was commissioned by Leopold II to make a second trip to the Congo in 1882, whereafter he was employed by a Rhenish company and despatched to Hereroland via the Cape in 1884–85.
Elsbeth von Leubnitz, his young wife whom he had married on 27 October 1881, travelled with him and they made a joint collection of plants.
Pechuel-loeschea leubnitziae was named after Elsbeth, and is quite possibly a unique case of genus and species honouring a husband and wife respectively.
