author
Known primarily for a lively biography of the explorer Emin Pasha, this early 20th-century writer brought distant history and travel to young readers in a clear, approachable way.

by M. C. Plehn
M. C. Plehn is the credited author of Emin Pasha, a short biographical work published in the "Life Stories for Young People" series and now available through Project Gutenberg. The book focuses on the life of Eduard Schnitzer, better known as Emin Pasha, and presents African exploration and colonial-era history for a general audience.
Reliable biographical information about M. C. Plehn is limited in the sources I could confirm. Some modern listings describe the author as a University of California economics professor, which strongly suggests this may be Carl C. Plehn, an American economist and longtime University of California professor best known for his work in public finance. Because the available sources do not clearly prove that identification in the book record itself, it is best treated as likely rather than certain.
