Maria Jacobsen: Maria Jacobsen (November 6, 1882 – April 6, 1960) was a Danish missionary and a key witness to the Armenian Genocide.  Jacobsen wrote the "Diaries of a Danish Missionary: Harpoot, 1907–1919", which according to Armenian Genocide scholar Ara Sarafian, is a "documentation of the utmost significance" for research of the Armenian Genocide.  For her humanitarian efforts, Jacobsen is known as "Mayrik" (Armenian: mother) or "Mama" for having saved many Armenians during the Genocide.

Armenian Genocide: The Armenian Genocide (Armenian: Հայոց ցեղասպանություն , "Hayots tseghaspanutyun"), also known as the Armenian Holocaust, was the Ottoman government's systematic extermination of 1.5 million Armenians, mostly Ottoman citizens within the Ottoman Empire and its successor state, the Republic of Turkey.  The starting date is conventionally held to be 24 April 1915, the day that Ottoman authorities rounded up, arrested, and deported 235 to 270 Armenian intellectuals and community leaders from Constantinople to the region of Ankara, the majority of whom were eventually murdered.  The genocide was carried out during and after World War I and implemented in two phases—the wholesale killing of the able-bodied male population through massacre and subjection of army conscripts to forced labour, followed by the deportation of women, children, the elderly, and the infirm on death marches leading to the Syrian Desert.  Driven forward by military escorts, the deportees were deprived of food and water and subjected to periodic robbery, rape, and massacre.  Other indigenous and Christian ethnic groups, such as the Assyrians and the Ottoman Greeks, were similarly targeted for extermination by the Ottoman government in the Assyrian genocide and the Greek genocide, and their treatment is considered by some historians to be part of the same genocidal policy.  Most Armenian diaspora communities around the world came into being as a direct result of the genocide.

He is the subject of the 1982 novel "Schindler's Ark" and its 1993 film adaptation, "Schindler's List", which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, and dedication to save the lives of his Jewish employees.

Mehmet Celal Bey: Mehmet Celal Bey (Ottoman Turkish: محمد جلال بك‎ ‎; 1863 – 15 February 1926) was an Ottoman statesman and a key witness to the Armenian Genocide.  During his career as a politician, Celal Bey served as governor of the Ottoman provinces associated with the cities Erzurum, Aleppo, Aydın, Edirne, Konya, and Adana.  He also served as minister of the interior and minister of agriculture as well as mayor of Istanbul.  Celal Bey is known for having saved many lives during the Armenian Genocide by defying deportation orders, which were preludes to starvation and massacres.

Today, he is often called the Turkish Oskar Schindler.

Armenian Genocide recognition: Armenian Genocide recognition is the formal acceptance that the systematic massacres and forced deportation of Armenians committed by the Ottoman Empire from 1915 to 1923 constituted genocide.  The consensus of historians and academic institutions on Holocaust and genocide studies recognize the Armenian Genocide.  However, despite the recognition of the genocidal character of the massacre of Armenians in legitimate scholarship as well as in civil society, at the governmental level nations have been reticent to officially acknowledge the killings as a genocide on account of political concern over their relations with the Republic of Turkey, the successor state of the Ottoman Imperial authorities which perpetrated the genocide.  The governments of Turkey and its close ally Azerbaijan are the only ones that directly deny the historical factuality of the Armenian Genocide, and both are adamantly opposed to the recognition of the genocide by other nations, threatening economic and diplomatic consequences to recognizers.

Grace Knapp: Grace H. Knapp (21 November 1870 – 14 March 1953) was an American Christian missionary and teacher who served in the Ottoman Empire.

Sentenced to life imprisonment, Yanikian was released on parole in January 1984.
