title: [Bioergography of Max Bürger].
abstract: For the inquiry into changes during ageing apart from the usual methods of the cross-sectional and longitudinal research the biographical analysis is at our disposal. The establishment of statistics of works is called bioergography. This method is particularly suitable for the recognition of changes of creativity of productive persons, as it is shown at the instance of Ludwig van Beethoven. The bioergography of Max Bürger reveals how form and essence of his work have changed in the course of his life without speaking about a decline of his vigour.
