Kapitän zur See Sieber

[den_stokes]

Hi Gentlemen!
Recently I was given this portrait, it was signed on the back:

Kapitän zur See Sieber
Kommandeur der Marine-Vermessungs-Abteilung, Standort Gronau b. Gotenhafen

I was searching for info about him and found KzS Adolf Sieber

Born: 25 Sep 1889

Highest rank reached: Kapitän z. See

Kdr Steuermannschule, Mürwik
Kdr Navigationsschule, Gotenhafen
Kdr Höheres Kommando der Navigationsschulen
Kdr Navigationsschule der Kriegsmarine, Gotenhafen

The stupid question: Is that one and the same man?

Does anybody have any information about his destiny?

Thanks in advance
Best Regards
Den
