Best known for a concise early-20th-century biography of African explorer and administrator Emin Pasha, this writer reached English-language readers through George P. Upton’s 1912 translation from German. Little biographical information about the author appears to be readily available today, which gives the work an added air of mystery.

by M. C. Plehn
M. C. Plehn is a little-documented author whose known work in English is Emin Pasha, a short historical biography first published in 1912 in the "Life Stories for Young People" series. Contemporary catalog and public-domain listings consistently connect the name with that book, and the translation credit shows that the original was written in German and translated by George P. Upton.
The book focuses on Emin Pasha, the physician, scientist, and colonial administrator whose life became part of the larger story of 19th-century African exploration. In keeping with the series it appeared in, Plehn’s writing seems aimed at making a complicated historical figure approachable for younger general readers while still keeping a clear interest in science, travel, and character.
Beyond that, confirmed personal details about Plehn are scarce in the sources currently available online. No reliable biographical profile or clearly verified portrait turned up in this search, so it is safest to let the surviving work speak for the author.
