family, the Württembergian Zellers. Her father was Reverend Johannes Zeller (1830–1902), leader of the Gobat School (est. in 1847) in Jerusalem, directed by the Church Missionary Society since 1877. Through her mother Maggie Zeller was a granddaughter of Jerusalem's Bishop Samuel Gobat and a niece of Dora Rappard. Maggie and Lepsius met in Ottoman Jerusalem. Johannes, who was on the board of the Syrian Orphanage from 1884 to 1886, met many problems in Jerusalem due to massacres inflicted on the Christian population in 1860. Johannes Lepsius house museum - Lepsiushaus was opened in 2011, Potsdam, Germany, in the house where Lepsius lived from 1908 to 1926. It is also a "Research Center for Genocide Studies". The Armenian genocide In 1914, Lepsius, Paul Rohrbach and Avetik Isahakyan created the German–Armenian Society, with Lepsius becoming the first chairman. Lepsius campaigned for the plight of Armenians to such an extent that by January 1916, mere mention of his name excited a disturbance in the Reichstag and "Lepsius' very name had become a synecdoche for embarrassing information". Lepsius is known for his documentation of the Armenian genocide.

Yet during the opening months of the First World War, there were mass arrests, deportations, and massacres of Armenians living in Eastern Anatolia. During this time, Lepsius founded humanitarian relief activities, and tried (unsuccessfully) to influence Germany, the Ottoman Empire's ally, which had thousands of soldiers and officers stationed throughout the Ottoman Empire. According to Ernst Jaeckh "At the time of World War I he introduced the Armenian protagonist. Dr. Lepsius, to the Turkish Generalissimo Enver Pasha, and through the author's [Jaeckh's] intervention the lives of many Armenians, particularly women and children, were saved." One of Lepsius' most important works is Germany and Armenia 1914–1918: Collection of Diplomatic documents, which later became considered as "the main document on the Armenian genocide."
