family of Angela Merkel
A genealogical overview of Angela Merkel's German and Polish family background, relatives, and marriages.
Last updated August 24, 2026
Overview
The family of Angela Merkel concerns the ancestry, immediate relatives, and marriages of Angela Dorothea Merkel, the former German chancellor. Merkel was born on 17 July 1954 in Hamburg and was raised primarily in East Germany after her father, Horst Kasner, moved the family there when she was an infant. Her family background combines German, Polish, Protestant, academic, and civic elements. The surname Kasner has Polish roots: Merkel's paternal grandfather was born Ludwik Marian Kaźmierczak in what is now Poznań, Poland, and the family name was Germanized to Kasner in 1930. This ancestry became part of the public discussion surrounding Merkel's biography, although her public identity was principally associated with German political life and the Federal Republic's reunification-era history. Merkel's father, Horst Kasner, was a Protestant theologian. After the Second World War he became a pastor and moved with his family from Hamburg to the German Democratic Republic. The family settled in the Templin area of Brandenburg, where Kasner was involved in Protestant church life. Merkel's mother, Herlind Kasner, née Jentzsch, was a teacher of English and Latin. She continued teaching English at an adult education centre in Templin well into later life. The professional backgrounds of both parents placed education, religion, and intellectual work at the centre of the household in which Merkel and her siblings grew up. Merkel's paternal grandfather, Ludwig Kasner, was born in 1896 and served in the Polish Blue Army during the struggle for Polish independence. After the First World War he moved to Berlin, where he worked for the police and married into a Berlin family. Her maternal grandfather, Willi Jentzsch, was an educator and politician in the Free City of Danzig. He served briefly as one of the city's senators after his election in 1926, later becoming rector of Gymnasium St. Johann and, in 1936, director of the city's elementary schools. These family histories connect Merkel's ancestry with the political and territorial changes of Central Europe in the twentieth century. Angela Merkel was the eldest of three siblings. Her younger brother, Marcus Kasner, born in 1957, became a theoretical physicist. Like his sister, he studied physics, completed doctoral research, and worked at the Academy of Sciences in East Berlin. He later obtained a habilitation at the University of Magdeburg and pursued an academic career in theoretical physics, including work on electronic correlation in the quantum Hall regime. He has been associated with the Institute for Theoretical Physics at Goethe University Frankfurt and has lived in Darmstadt. During the final years of East Germany, Marcus Kasner participated in opposition discussions and was connected with people involved in the Democratic Awakening movement. After reunification, he was associated with Alliance 90/The Greens. Merkel's sister, Irene Kasner, born in 1964, became an occupational therapist. Merkel's marital history is also part of the family subject. She met physicist Ulrich Merkel while they were students in 1974, and they married in 1977. The marriage ended in divorce in 1982, but Angela Merkel retained the surname Merkel and used it throughout her political career. In 1998 she married Joachim Sauer, a quantum chemist and professor at Humboldt University of Berlin. Their marriage linked Merkel's private life to another prominent academic career, although Sauer generally maintained a low public profile during her chancellorship. The family received extensive public attention because Merkel became one of Europe's most influential political leaders, serving as German chancellor from 2005 to 2021. A 2013 biography contributed to wider discussion of her family origins, East German upbringing, Polish ancestry, education, and relationships. The family is not a commercial organization or product brand; it is the subject of a biographical and genealogical article. Accordingly, it has no p…
History
The family history associated with Angela Merkel spans German, Polish, East German, Protestant, academic, and civic contexts. Merkel was born Angela Dorothea Kasner in Hamburg on 17 July 1954. Her father, Horst Kasner, was a Protestant theologian, and her mother, Herlind Kasner, was a teacher of English and Latin. Soon after Merkel's birth, Horst Kasner moved the family to East Germany, where he pursued pastoral work. Merkel grew up in the Templin region of Brandenburg, within the political and social environment of the German Democratic Republic. The Kasner surname has a Polish origin. Merkel's paternal grandfather, Ludwig Kasner, was born Ludwik Marian Kaźmierczak in 1896 in Posen, now Poznań. He served in the Polish Blue Army during Poland's independence struggle after the First World War. He later moved to Berlin, where he worked for the police and became associated with the Kasner family name after its change in 1930. This branch of the family illustrates the complex movement of people and identities between German and Polish territories during the period after the First World War. Merkel's maternal line was connected to education and public administration in the Free City of Danzig. Her maternal grandfather, Willi Jentzsch, was born in Wolfen in 1886. He worked as a teacher and school administrator and became one of the senators of the Free City of Danzig in 1926. He resigned the following year to become rector of Gymnasium St. Johann. In 1936 he became director of elementary schools in Danzig, placing him at the head of the city's primary-school system. His career formed part of the educational inheritance of Merkel's maternal family. Angela Merkel's parents emphasized education and professional achievement. Her mother continued teaching English at an adult education centre in Templin into her eighties. Merkel's only brother, Marcus Kasner, followed a scientific path. He studied physics, completed a doctorate, worked as a researcher at the Academy of Sciences in Berlin, and later completed a habilitation at Otto von Guericke University Magdeburg. His research included theoretical work on electronic correlation in the quantum Hall regime, and he later taught and researched at Goethe University Frankfurt. Merkel's only sister, Irene Kasner, became an occupational therapist. During the political changes that preceded the end of East Germany, Marcus Kasner took part in opposition discussions in a circle that also included figures connected with the Democratic Awakening movement. After German reunification he was associated with Alliance 90/The Greens. Angela Merkel entered public life during the same broad period of political transformation, first becoming involved in East German political activity before rising through the Christian Democratic Union and federal government. Angela Merkel's first marriage was to Ulrich Merkel, a physicist whom she met while studying at university. They married in 1977 and divorced in 1982. She retained the surname Merkel after the divorce. On 30 December 1998 she married Joachim Sauer, a quantum chemist and professor at Humboldt University of Berlin. Merkel's relationships, parental background, siblings, and ancestry were discussed more extensively as her political importance grew. A biography published in 2013 helped bring these family details to a broader readership. The family article is biographical rather than commercial. It documents relatives and ancestry connected with a major German political figure, not an enterprise, consumer brand, or institution. No independent family organization, business ownership, product line, or corporate structure is identified in the available material.
