This theatre play provides insight into the eventful life and scientific struggle of Victor F. Hess – the discoverer of cosmic radiation. Based on historic accounts and personal letters, the unique character of the much acclaimed scientist is portrayed through several key episodes of his life. From the famous balloon-flight in 1912 to the research at the Hafelekar-observatory high above Innsbruck, from receiving the Nobel prize in physics to the dramatic escape from Nazi-Germany on the eve of World War II.Written by an Innsbruck physicist, the play attempts to let history and science meet up on stage. After a series of performances in Austria and Germany, this new English version (translated by Arthur Breisky – grandson of Victor F. Hess) will allow a wider audience to enjoy this intimate portrait of a great scientist and his important discovery of cosmic rays.
