Who married Lina Heydrich?

Lina Mathilde Manninen (née von Osten, formerly Heydrich; 14 June 1911 – 14 August 1985) was the wife of Reinhard Heydrich, head of the Reich Security Main Office and a central figure in Nazi Germany. The daughter of a minor German aristocrat (he worked as a village schoolteacher), she joined the Nazi Party in 1929 and met Reinhard Heydrich in December 1930. The two wed on 26 December 1931 and had four children. She published a memoir in 1976. She defended the reputation of her first husband (Heydrich) until her death at age 74 in August 1985 in Fehmarn.

Reinhard Tristan Eugen Heydrich ( HY-drik, [ˈʁaɪnhaʁt ˈtʁɪstan ˈʔɔʏɡn̩ ˈhaɪdʁɪç] ; 7 March 1904 – 4 June 1942) was a high-ranking German SS and police official during the Nazi era and a principal architect of the Holocaust. He held the rank of SS-Obergruppenführer und General der Polizei. Many historians regard Heydrich as one of the darkest figures within the Nazi regime. Adolf Hitler described him as "the man with the iron heart."

Heydrich was chief of the Reich Security Main Office (including the Gestapo, Kripo, and SD). He was also Stellvertretender Reichsprotektor (Deputy/Acting Reich-Protector) of Bohemia and Moravia. He served as president of the International Criminal Police Commission (ICPC, now known as Interpol) and chaired the January 1942 Wannsee Conference which formalised plans for the "Final Solution to the Jewish question"—the deportation and genocide of all Jews in German-occupied Europe.

He was the founding head of the Sicherheitsdienst (Security Service, SD), an intelligence organisation charged with seeking out and neutralising resistance to the Nazi Party via arrests, deportations, and murders. He helped organise Kristallnacht, a series of coordinated attacks against Jews throughout Nazi Germany and parts of Austria on 9–10 November 1938. The attacks were carried out by SA stormtroopers and civilians and presaged the Holocaust. Upon his arrival in Prague, Heydrich sought to eliminate opposition to the Nazi occupation by suppressing Czech culture and deporting and executing members of the Czech resistance. He was directly responsible for the Einsatzgruppen, the special task forces that travelled in the wake of the German armies and murdered more than two million people by mass shooting and gassing including 1.3 million Jews.

Heydrich was mortally wounded in Prague on 27 May 1942 as a result of Operation Anthropoid. He was ambushed by a team of Czech and Slovak soldiers who had been sent by the Czechoslovak government-in-exile to kill him; the team was trained by the British Special Operations Executive. Heydrich died from his injuries on 4 June 1942. Nazi intelligence falsely linked the Czech and Slovak soldiers and resistance partisans to the villages of Lidice and Ležáky. Both villages were razed; the men and boys age 14 and above were shot and most of the women and children were deported and murdered in Nazi concentration camps.
