Karl Adolf Spieß (3 February 18109 May 1858) was a German gymnast and educator who contributed to the development of school gymnastics for children of both sexes in Switzerland and Germany. Biography Father Spiess's father, Johann Balthasar Spiess (1782–1841) and himself the son of a Thuringian farmer and master smith, had first prepared himself for a position as teacher in the elementary schools, but after some years of professional experience at Frankfurt am Main decided upon further study, and so completed a course in theology at the University of Giessen, and immediately after passing his examination, in 1807, became teacher and sub-rector at the Latin school in Lauterbach. There he brought his bride Luise Werner, of Saarbrücken, who he had first met in Frankfurt. Adolf Spiess, born in Lauterbach, Hesse, was the oldest of their five children.

It was therefore natural that one feature of the daily program should be gymnastics, as described and practised by GutsMuths — walking the balance beam, jumping, running, climbing, throwing, skating, swimming, etc., and games of all sorts. Every week throughout the year there were also excursions with teachers, and dancing lessons were given in the winter months. Education Adolf Spiess entered his father's school at the age of six or less. A few years later, in 1819, Fritz Hessemer, just back from the University of Giessen, made the pupils acquainted with the new Jahn gymnastics, and parallel bars and a horizontal bar were now added to the equipment. In 1824 some of the boys organized a little society for the purpose of practising gymnastics regularly outside of school hours. They met in the private garden exercise area () of Councillor () A. André, using Jahn's Deutsche Turnkunst as a guide. They soon met other turners in Hanau, a few miles to the east, with whom joint excursions on foot to
