Theodor Oelenheinz (1872–1951) was a German lawyer, author, and legal theorist known for his 1919 publication Abolition of Inheritance (Abschaffung des Erbrechts), a socially progressive proposal for reforming inheritance law in the aftermath of World War I. He was also involved in publishing, political activism, and held affiliations with various political and professional organizations throughout his life.

Early life and education Oelenheinz was born in 1872, the son of a bank director from Karlsruhe. He was the grandson of Karl Georg Hoffmann, former finance minister of the Grand Duchy of Baden, and the brother of artist and architect Leopold Oelenheinz.:Generallandesarchiv Karlsruhe. 465 c_722.

Legal career and military service before and during WWI He worked as a lawyer in Mannheim and Heidelberg from 1899 to 1941. Between 1890 and 1919, he served intermittently in the military, leaving with the rank of captain and good certificates about his achievements and character.Generallandesarchiv Karlsruhe 456 E Nr. 8725.

Around 1910, he was promised appointment to the Oberster Kolonial- und Konsulargerichtshof (Colonial and Consular Supreme Court),Hamburger Echo., Jahrgang 25, Ausgabe 35, 10.2.1911.

Landgericht Mannheim: Dienstakten der Rechtsanwälte / 1894-1999. p.5 http://www.landesarchiv-bw.de/plink/?f=4-5418438

At the end of WWI, Oelenheinz served as head of the reconnaissance unit at German army's Generalkommando Karlsruhe in its Mannheim branch. In this capacity, his task was to lead the promotional activities for the war bonds (Kriegsanleihe) campaign, despite being an outspoken critic of this way of financing the war vis-a-vis taxation as done by England and France.Oelenheinz (1924): "Volkserhebung wider das Unrecht. Vortrag gehalten bei der Gründung der 131. Ortsgruppe des Hypotheken- und Spar-Gläubiger-Schutzverbandes für das Deutsche Reich, Sitz Berlin-Biesdorf." Mannheimer Vereinsdruckerei. 1924. p.1

Publishing and legal activism (1919–1933) After World War I, during the early Weimar Republic, Oelenheinz served as head of the propaganda office for cashless payments in the district of Lower Baden at the Reichsbank.Oelenheinz (1924): "Volkserhebung wider das Unrecht. Vortrag gehalten bei der Gründung der 131. Ortsgruppe des Hypotheken- und Spar-Gläubiger-Schutzverbandes für das Deutsche Reich, Sitz Berlin-Biesdorf." Mannheimer Vereinsdruckerei. 1924. p.2 In his own view, this position — along with his wartime role in promoting war bonds — gave him particularly close insight into the illegitimate devaluation of war bonds during the period of hyperinflation. This experience, he claimed, motivated him to pursue legal action and political activism against the government's handling of the crisis, incl. the publishing of Volkserhebung wider das Unrecht ("People's Uprising Against Injustice").Oelenheinz (1924): "Volkserhebung wider das Unrecht. Vortrag gehalten bei der Gründung der 131. Ortsgruppe des Hypotheken- und Spar-Gläubiger-Schutzverbandes für das Deutsche Reich, Sitz Berlin-Biesdorf." Mannheimer Vereinsdruckerei. 1924. p.2 This declaration denounced the government's inflation policies as unprecedented injustice and illegality.

Both of Oelenheinz larger publications were written during the early Weimar Republic: The Abolition of Inheritance in 1919, and Das Erfindungsrecht in 1922/1923. In 1922, he became founding member of the Staatsorganische Gesellschaft, a Mannheim-based association to promote scientific investigations into the principle that the state must be perceived as part the natural organic systems.Mannheimer General-Anzeiger. 1916-1924. 1921. 98 (28.2.1921).

Involvement with Nazi-related institutions (1933–1945) Oelenheinz was a member of or affiliated with a number of Nazi associations,Generallandesarchiv Karlsruhe 240-2 Nr. 429. Oberlandesgericht Karlsruhe - Personalakten / 1884-1996. http://www.landesarchiv-bw.de/plink/?f=4-5418438 including: The nationalist Pan-German League, a predecessor of the NSDAP The subgroup of commercial lawyers in the German Association of Economists (Reichsverband Deutscher Volkswirte) Lawyer Society of Nazi Germany (NSRB / BNSDJ, 1933–1944) SA patron member until January 1933 and SS patron member since August 1933 Financial supporter of the NSDAP via the Opferring since 1932

In 1932, in his capacity as chairman of the German Business Association (Deutscher Wirtschaftsverein), Oelenheinz promoted a nationalist concept of "German fashion." In a speech given at an event with the Deutschnationaler Handlungsgehilfen-Verband (a nationalist and antisemitic white-collar union), he argued that this had a "national-ethical educational value" and served to combat "foreignness". This led him to be engaged with the founding of the Nazi fashion agency Deutsches Modeamt in Berlin around June/July 1933,Hakenkreuzbanner newspaper from 5.7.1933. https://nbn-resolving.org/urn:nbn:de:bsz:mh40-258146 which was later renamed into Deutsches Mode-Institut.

Postwar rehabilitation and death Despite his affiliations and financial support of the early Nazi period, Oelenheinz never became an NSDAP member. His file at the Lawyer Society reveals several rebukes for non-conforming behavior; colleagues accused him of agitating against the NSDAP.Generallandesarchiv Karlsruhe. 465 c_722. Personalakte Bund Nationalsozialistischer Deutscher Juristen. p.4, p.6, p.15 https://www.deutsche-digitale-bibliothek.de/item/AUMWW5ZYUPZTES7OR4KJEJINQTYM3FSW After World War II, authorities in both West and East Germany referred to him as an "antifascist"; he was declared "not affected" during denazification.Generallandesarchiv Karlsruhe 240-2 Nr. 429. Oberlandesgericht Karlsruhe - Personalakten / 1884-1996. http://www.landesarchiv-bw.de/plink/?f=4-5418438

Oelenheinz regained his license to practice law in Mannheim in 1950, unsuccessfully pursued a late habilitation at the University of Heidelberg, and appeared as a witness in court cases against Nazi criminals.

In February 1951, Oelenheinz was elected the first chairman of the Heidelberg district committee for the People's Referendum against the Remilitarization of Germany."Gegen Remilitarisierung". Mannheimer Morgen. Ausgabe Mannheim. 1946-19606 (1951)67 (20.3.1951). No. 16, 21 February 1951, p. 2. Retrieved from marchivum.de. The referendum, while part of the broader Ohne mich movement, was supported by the Communist Party of Germany (KPD) and held in parallel to an official referendum with the same content in East Germany. It was ultimately banned by the West German government, despite more than 6million collected votes against the remilitarisation."Deutschland, 5.

Oelenheinz died in late 1951.

Abolition of inheritance (1919) In the 19th century, inheritance tax was often promoted as an effective means of social revolution and reform, with moderates seeking to restrict inheritance rights and more radical approaches seeking to abolish them altogether. Oelenheinz book Abolition of Inheritance (original title Abschaffung des Erbrechts)Oelenheinz (1919). Abschaffung des Erbrechts. Mannheim. https://aksearch.arbeiterkammer.at/Record/990000862690203343 falls into the latter category.Birnbaum (2007): "Leistungsfähigkeitsprinzip und ErbStG ". Münsterische Beiträge zur Rechtswissenschaft Band 174. Duncker & Humblot. Berlin

The book is structured as a formal legislative proposal describing a new inheritance regime. He attempted to strike a balance between Marxist abolition of private property and capitalism. His concept introduced the idea of "property for life", abolishing the right to extend property beyond death. He also proposed a clear distinction between revenue-generating assets (e.g., land, financial assets, rental property, machinery) and private-use goods (e.g., clothing, personal residence, household items, a savings allowance equal to the last annual salary of the deceased).Oelenheinz (1919). Abschaffung des Erbrechts. Mannheim. §1 and §2 https://aksearch.arbeiterkammer.at/Record/990000862690203343

Mixed-use properties (such as a self-inhabited house with rental units) were classified as revenue-generating and not inheritable. Debt linked to such assets would be assumed by the state, while private debt would remain with the heirs. Dependents were to receive annuities based on the social status of the deceased, funded by interest from confiscated assets. If insufficient, the assets themselves could be gradually liquidated. Ultimately, the state bore responsibility for providing for dependents.Oelenheinz, Theodor (1919). Abschaffung des Erbrechts. Mannheim. §5 https://aksearch.arbeiterkammer.at/Record/990000862690203343
