== Life ==
In his childhood Gerstenberg lived in [Pyritz](/source/Pyrzyce). Gerstenberg studied mathematics and philosophy in Berlin. Since 1873 Gerstenberg worked as mathematician for assurance '' Allgemeinen Eisenbahn-Versicherungs-Gesellschaft'', which later became German assurance ''Victoria''. In 1888, Gerstenberg became member of supervisory board in that assurance and was since 1891 CEO of the assurance.
In 1884, Gerstenberg married Elise Wilhelmine Winzerling, with her he had two daughters. The family home was first at ''Großbeerenstraße'' in Berlin-[Kreuzberg](/source/Kreuzberg) and later in Berlin-[Lichterfelde](/source/Lichterfelde_(Berlin)). His daughter Margarete married physicist Hans Georg Scharf.
Gerstenberg collected art. During [World War II](/source/World_War_II), part of his collection was destroyed and other works were seized from [Nazi Germany](/source/Nazi_Germany), ending up in Russian museums.[[http://www.tagesspiegel.de/kultur/ausstellungen-alt/die-helle-seite-der-nacht/1276860.html Sammlung Scharf-Gerstenberg: Die helle Seite der Nacht] Nicola Kuhn, ''[Der Tagesspiegel](/source/Der_Tagesspiegel)'', 11 July 2008.
