Measured quantities and their uses - The development of statistics in Berlin (1886-1945) Annette B. Vogt The discipline social statistics was well developed in Berlin, from 1886 onwards at the Berlin University - when the economic-statistical seminar (Staatswissenschaftlich-statistisches Seminar) was founded -, and from 1906 onwards also at the Berlin School of Economics (Handels-Hochschule). Furthermore, in Berlin were several statistical offices, which were called bureau until late 19th century. In 1805 the statistical bureau of the Prussian country (Königlich Preußisches Statistisches Bureau, 1805-1934) was opened. In 1862 the statistical office of the town Berlin was established (Statistisches Bureau der Stadt Berlin, 1920-1945 von Groß-Berlin) which was the first office of a town in Germany. In 1872 the statistical bureau of the German Empire (Kaiserliches Statistisches Amt, 1918-1945 Statistisches Reichsamt) was established. In comparison, mathematical statistics was developed to a much lesser extent. The purposes of these statistical offices were the collection of data and to measure the socio economic variables like economic growth, levels and rates of the economic growth, inflation, unemployment etc. to get measured quantities (statistical information) about the economy and the society of their town (Berlin), the country (Prussia) and the state (the German Empire). In my paper I will discuss the following questions: How these purposes did influenced the development of statistics in Berlin at the Berlin University and the Berlin School of Economics from 1886 until 1945? Did measurement as such exist in economic statistics, and what was meant "to measure the socio economic variables" at that time? How statistics was tought and by whom at the Berlin University (1886-1945) and at the Berlin School of Economics between 1906 (from 1935 until 1945 it was named Business School (Wirtschafts-Hochschule)) and 1945? The professors, teachers and lecturers belonged not only to the staff of the Berlin University and the Berlin School of Economics, but were also employed in the different statistical offices in Berlin, others were working in insurance companies or unions. How the topics of lectures and the topics of publications were changed during this period, especially after 1933 because of the Nazi regime, when many important economists, statisticians and mathematicians were forced to leave Berlin resp. Germany and had to go into Exile. if possible - into symposia S 045
