Untersuchungen über die Ermittlung von Wahrscheinlichkeiten.

The doctoral dissertation of Rudolf Laemmel, produced under the auspices of Burkhardt of Zurich, and the first attempt at founding probability theory on set theory and measure theory (the axiomatization of probability). The work discusses the rules

of total and compound probability as axioms. The rule of compound probability is stated only in the case of independence, a concept he did not explicate. The work is mentioned by John Maynard Keynes in his Treatise on probability. Rudolf Laemmel (1879-1962) was an educational reformer and writer.
