Karl Renner
Not all chancellors live to become the oldest of their time. Of the 20 deceased chancellors, 8 eventually became the oldest of their time, while 12 did not. On one occasion the oldest living chancellor lost this distinction not by his death, but due to the appointment of a chancellor who was older. Karl Renner lost this distinction when Michael Mayr was appointed, but when Mayr died in 1922, Renner regained it again until his own death in 1950 for a record total period of 30 years and 110 days. Ernst Streeruwitz became the oldest living chancellor after the death of Karl Renner, but he survived Renner by only 1 year and 293 days.
