Otto Volger

[5] In early 1849, Volger was forced to flee Germany to Switzerland after an investigation was opened against him following a violent riot at Plesse Castle.

[6]On 10 November 1859, the 100th birthday of Friedrich Schiller, Volger founded the Freies Deutsches Hochstift, an association for general education located in Frankfurt.

Volger founded the Hochstift to be a ""Bundestag" of the German spirit",[9] a place where those who held the pan-German ideas of the 1848 revolution were to find a spiritual and cultural home.

[20] A memorial stone was also placed on Volger's grave in Frankfurt Main Cemetery, noting his contribution to the Freies Deutsches Hochstift.

He did extensive study of earthquakes in Switzerland; researching their origins, periodicity, meteorological and environmental factors, as well as the spread and expansion of the quakes.
