|Spouse(s)||Hanns Martin Schleyer (1939–1977, his death)|
Waltrude Ketterer Schleyer (21 January 1916 – 21 March 2008) was the widow of Hanns Martin Schleyer, a high ranking German official and former Nazi who was killed by the Red Army Faction which shocked West Germany during the 1970s. 
She married Schleyer in 1939. She was the daughter of the physician, city councillor of Munich and SA-Obergruppenführer Emil Ketterer. They had four sons.
During the couple's times in Prague, Waltrude Schleyer lived in a formerly Jewish owned house whose owner died in a German concentration camp within in the same time period.
Schleyer's husband, Hanns Martin Schleyer, was the head of the employers association in West Germany and a former SS lieutenant. He was kidnapped and then killed by the Red Army Faction (RAF) in 1977. The RAF was also known as the Baader-Meinhof gang, which was named after two of the group's early leaders, Andreas Baader and Ulrike Meinhof. The RAF was a radical Communist terrorist group, with a Marxist-Leninist ideology, which sought to overthrow the West German government, which was capitalist and a close ally of the United States during the Cold War.
The RAF kidnapping of Martin Schleyer was intended to force the West German government to release Andreas Baader and three other RAF members. Baader and the other RAF members were being held at the Stammheim prison near the city of Stuttgart. The West German government refused to give into RAF's demands or negotiate. The RAF sent the government a picture of Hanns Martin Schleyer alive, but in captivity, on October 8, 1977. On October 18, 1977, on learning that three of their members had been found dead in prison, the RAF killed Martin Schleyer. His body was found on October 19, 1977, in a car in Mulhouse, France, which is just across the border from Germany. The RAF disbanded itself in 1998.
Waltrude Schleyer advocated against clemency for RAF members who had killed her husband. One of Martin Schleyer's kidnappers, Christian Klar, was refused a pardon by German President Horst Koehler, but was released on 19 December 2008. Other former RAF terrorist members have also been granted clemency and released. These moves were sharply opposed by Waltrude Schleyer.
Waltrude Schleyer died on March 21, 2008, at the age of 92 in Stuttgart, Germany. Her death was announced in the Stuttgarter Nachrichten daily newspaper, which did not give a cause of her death.
