Schweitzer was born at
Frankfurt am Main, of an old aristocratic
Catholic family. He studied
law in
Berlin and
Heidelberg, and afterwards practised in his native city. He was, however, generally more interested in politics and literature than law. Schweitzer was attracted by the
social democratic movement, then led in Germany by
Ferdinand Lassalle. Lassalle defended him from calls for his expulsion from the movement after he was convicted of a public indency charge for
pederasty in 1862. Historian
Gustav Mayer in 1909 described the incident as follows: Schweitzer served two weeks in jail in Bruchsal for the offence. Lassalle argued that the "abnormality attributed to Dr. von Schweitzer has nothing whatever to do with his political character." After Lassalle's death in 1864, Schweitzer on 20 May 1867, became president of the
General German Workers' Association (, ADAV). The ADAV began fracturing soon thereafter, as disputes over whether to cooperate with
Otto von Bismarck's government led
Wilhelm Liebknecht and others to leave the ADAV in the years after 1864. Liebknecht and
August Bebel founded the
Social Democratic Workers' Party of Germany (, SDAP) in 1869. Schweitzer edited the ADAV's newspaper
Der Sozialdemokrat (English:
The Social Democrat), which brought him into frequent trouble with the
Prussian government. On 7 September 1867, he was
elected as a deputy to the
Reichstag of the North German Confederation, with the help of Lassalle. In an article for
Der Sozialdemokrat on 7 October 1868, he coined the term "
democratic centralization", now known as democratic centralism, to describe the structure of the ADAV. On his failure to secure election to the newly formed
German Reichstag on 3 March 1871, he resigned the presidency of the ADAV and retired from political life. The ADAV later merged with the SDAP at the
Gotha Congress in 1875 to form the Socialist Workers' Party of Germany (, SAPD), the forerunner of the modern-day
Social Democratic Party of Germany (SPD). He died of pneumonia in Giessbach,
Switzerland on 28 July 1875. == Conflict with Karl Marx and Friedrich Engels ==
