Walter Steinert
Remembered today mainly through a single surviving book, this little-known coauthor helped create a practical German grammar guide meant for students and teachers. The scarcity of biographical records gives the work an extra sense of age and curiosity.

About the author
Walter Steinert is a very obscure author in the historical record. Based on the sources available here, he is credited as coauthor of Kleine deutsche Sprachlehre, a German-language grammar handbook written with Hermann Bohm.
Project Gutenberg lists only that one work under his name, and the book is described as a concise, practical guide to German grammar for learners and educators. The text appears to come from the late 19th century, but I could not confirm reliable details about Steinert's life beyond his connection to that publication.
Because trustworthy biographical information is so limited, the safest picture is a modest one: Steinert seems to have been an educational writer or collaborator whose legacy survives chiefly through this straightforward grammar book.
