author
Known today mainly through Project Gutenberg listings, this author is associated with early 20th-century public-domain works. Reliable biographical details appear to be scarce online, which gives the name a quiet air of mystery.

by E. Mittleman
Project Gutenberg lists works by E. Mittleman, confirming the author’s presence in the public-domain record. Beyond that, I could not verify enough reliable biographical information from the sources available here to safely add details about background, dates, or career.
Because the record is so thin, it’s best to treat E. Mittleman as an author whose surviving reputation rests more on the books themselves than on a well-documented personal history. If more authoritative sources surface, this profile could be expanded.
