Biographical Note

Hugo Sinzheimer (1875-1945) was born in Worms. He studied law in Berlin, Freiburg, Marburg und Halle, and he completed his dissertation in 1898 at the University of Heidelberg. He was among the founders of the field of labor law, and helped shape modern labor law as a member of the Weimar National Assembly. He was a professor at the University of Frankfurt from 1920 until April 1933, when he fled to the Netherlands. There, he obtained positions at the Universities of Amsterdam and Leiden. Sinzheimer died suddenly in September 1945, after having survived the war in hiding. His daughter Gertrud Mainzer survived Bergen-Belsen and after the war immigrated to New York, where she became a noted family court judge.

Divided into two subseries: Subseries 1: General and Subseries 2: Writings and Research.

Scope and Content:

Series II contains materials relating to Hugo Sinzheimer's professional activity as a labor lawyer and professor. It is divided into two subseries.

Subseries 2 additionally includes some research notes.

Subseries 1: General, 1893-2001

0.75 linear ft.


Scope and Content:

This subseries includes correspondence, material relating to Sinzheimer's teaching, some photographs and several bound manuscripts of notes.

The general correspondence is primarily of a professional nature, mostly from attorneys and students. The signatures were difficult to decipher, so the folder is organized chronologically. The case file folder contains correspondence and legal briefs concerning the case of one Erich Seligmann-Heilner and his attempts to secure dividend payments from the company Continentale Linoleum-Union; several drafts of the completed legal documents are present in Section C: Other Articles of Subseries 2. The Educational Materials folder contains a seminar book that appears to have been maintained collaboratively by Sinzheimer and his students. The folder also contains an undated set of notes from the Foundations of Labor Law class taught by Sinzheimer. Related is a folder of essays by his students. The folder of materials about Hugo Sinzheimer includes book reviews, clippings, and items relating to conferences about him. This subseries also contains a few unidentified photographs.

The subseries also includes three sets of bound manuscript notes taken by Hugo Sinzheimer during lectures on macroeconomics and private law. The lectures were titled: Nationaloekonomische u[nd] socialpolitische Ferien Kurse, veranstaltet vom Verein fuer Socialpolitik, Berlin (9/30 – 10/14/1895); Rosin: Deutsches Privatrecht (mit Lehenrecht), Freiburg i/Br. (1895); and Schmoller: Praktische Nationaloekonomie oder Volkswirtschaftsp[olitik] (preussisch-deutsche Wirtschaftsgeschichte der Gegenwart) (undated). These items have been microfilmed; please use MF 1050.

Subseries 2: Writings and Research, 1910-2010

1.75 linear feet.

Subdivided as follows:

Scope and Content:

Subseries 2 consists of material relating to Sinzheimer's publications, especially his work Jüdische Klassiker der deutschen Rechtwissenschaft (Jewish Classics in German Jurisprudence). Other writings include a number of examples of journal and newspaper articles by him on various legal subjects, as well as a publisher's catalog and a copy of a Reichs-Arbeitsblatt with Sinzheimer's proposal for a labor law.

The bulk of Subseries 2 focuses on Sinzheimer's abovementioned book. The section "Full Manuscript" consists of the book's galley proofs and an annotated typescript. The typescript was left in the order in which it was found. Later additions to the collection, consisting of the remaining sections of this subseries, include heavily annotated manuscripts and typescripts for individual chapters, frequently with several versions of a chapter. These folders have been arranged in the order in which the chapters appear in the book. A proposal for the book and an unidentified fragment are also present.

Other later additions to this subseries include drafts of other articles and a number of folders of research notes. Among the articles are two drafts on the Seligmann-Heilner case, whose correspondence will be found in the first subseries of this series. Other articles include a legal article that comments on the use of reason and rationality in civil law, an article on economic democracy written while he was a professor at the University of Amsterdam. A third, handwritten article discusses the concept of the personality, with focus on self-awareness.

Subseries 2 additionally holds many folders of research notes, most of which pertain to legal issues. Several hold typed citations for specific books. Others are unidentified and were assigned topics during processing based on their contents. Three large folders, identified only by Roman numerals, consist of numerous handwritten notes and have been left in the order in which they were found without further subdivision.
