author
Known from a late-19th-century scientific contribution on freshwater insect life, this little-documented writer appears in Project Gutenberg as one of the contributors to a classic German introduction to pond and lake organisms. The surviving record is sparse, but the work itself points to a practical interest in observing the creatures of inland waters.

Project Gutenberg lists E. Schmidt-Schwedt as a contributor to Die Tier- und Pflanzenwelt des Süsswassers. Zweiter Band, a German scientific volume about the animals and plants of freshwater habitats. In that text, the contribution attributed to Schmidt-Schwedt is identified as being written in Berlin and focuses on the insect world of fresh water.
Beyond that contribution, reliable biographical information is hard to confirm from the sources available here. No clear mainstream reference entry or verified author biography was found, so it is safest to describe E. Schmidt-Schwedt as a little-documented scientific writer or contributor associated with late-19th-century freshwater natural history.
That obscurity adds a certain historical interest: Schmidt-Schwedt appears as one of the many specialists whose concise, observational writing helped shape popular and scientific introductions to aquatic life in German-speaking Europe.
