Among the considerable number of cities which soon followed the example of Kansas City in introducing systematic instruction in gymnastics into the public schools under the direction of graduates from the Normal School of the _Turnerbund_ were Chicago, in 1886, under Henry Suder (class of ’75); Davenport, Iowa, 1887, under William Reuter (’78); Cleveland, Ohio, 1887, under Karl Zapp (’75); St. Louis, 1890, under George Wittich (’82); Sandusky, Ohio, 1890, under Hans Ballin (’90); Columbus, Ohio, 1892, under Anton Leibold (’77); Cincinnati, Ohio, 1892, under Carl Ziegler (’86); Milwaukee, 1892, under Hans Rasmussen (’88); and Dayton, Ohio, 1892, under Robert Nohr (’90). Schoolroom manuals like those of Betz were published by Ballin, Leibold, and Rasmussen.[273] Karl Kroh (’79) was head of the department of physical training in the Cook County, Illinois, Normal School 1891-1899, and in the University of Chicago School of Education 1901-1907. William A. Stecher (’81), after three years as supervisor of physical training in the public schools of Indianapolis (1904-1906), was appointed director of physical education in the Philadelphia schools in January of 1907; and in the same year George Wittich (’82), who had been successor to Brosius at the Normal School of the _Turnerbund_, became supervisor of physical training in the Milwaukee schools. Reports from societies to the National Executive Committee under date of January 1, 1920, show that in 51 cities 171 men and 91 women graduated from the Normal School of the _Turnerbund_ (now known as the Normal College of the American Gymnastic Union) were employed as teachers in the public schools. The varying fortunes of the _Turnerbund_ since 1886 are suggested by the following table, compiled from statistical reports which reveal conditions in the constituent societies on January 1 of the year mentioned. -----+----------+-----------+--------+----------------+--------- Year.|Societies.|Membership.| Active | In classes for |Teachers | | |members.+-------+--------+employed. | | | | Boys. | Girls. | -----+----------+-----------+--------+-------+--------+--------- 1887 | 237 | 26,722 | 5704 |14,123 | 4,765 | 104 1890 | 277 | 35,912 | 7337 |17,145 | 7,735 | 148 1893 | 316 | 41,877 | 7604 |17,389 | 8,702 | 172 1895 | 314 | 39,870 | 7647 |18,879 | 9,992 | 180 1900 | 258 | 33,964 | 5675 |17,252 | 9,756 | 166 1905 | 244 | 37,090 | 5843 |18,033 |10,823 | 167 1910 | 234 | 39,207 | 5134 |12,870 | 7,897 | 146 1915 | 218 | 37,941 | 4989 | 9,264 | 7,958 | 165 1920 | 186 | 33,853 | 4135 | 6,782 | 6,958 | 125 -----+----------+-----------+--------+-------+--------+---------
