Freiherr von Georg-Günther Forstner

Born in 1882, Georg-Günther, Freiherr von Forstner is chiefly remembered as a German U-boat commander and as the author of The Journal of Submarine Commander von Forstner, published in English in 1917. The surviving catalog and archival records identify the book as a personal war narrative connected with German submarine operations in World War I.

That journal helped bring a rare, close-up view of submarine warfare to a wider audience at a time when the conflict was still unfolding. Rather than being known today for a large body of literary work, he is notable for this focused, firsthand record of naval service and wartime experience.

He died in 1940. I wasn't able to confirm many additional biographical details from reliable online sources, so this overview stays close to the facts that could be verified.
