As early as 1881 Dr. Sargent had begun to train teachers, in the “Sanatory Gymnasium” opened in Cambridge that year, primarily to meet the needs of young women studying in the “Harvard Annex,” now known as Radcliffe College. In 1883 accommodations were secured at 20 Church Street, and here during the next two decades more than two hundred and fifty women completed the prescribed two years’ normal course of theory and practice. The commodious new building on Everett Street was ready for use in the school year 1904-1905, and the course, now extended to cover three years, was thrown open to men also. Summer courses in physical training, lasting five weeks and given in Hemenway Gymnasium under the auspices of Harvard University, have been offered since 1887. The annual attendance in the first twenty-five years averaged over one hundred students, of whom nearly one third were men.[264] The continuous and rapid development of physical education in American colleges and universities which has taken place in recent years may be dated from the opening of the new Hemenway Gymnasium at Harvard University, with Dr. Sargent’s novel equipment and methods, in January of 1880, and the publication of Dr. Hartwell’s report by the Bureau of Education in 1886. First came an era of gymnasium building. In the brief interval between the two events just named the list of institutions includes Smith College (1880, $4000), Lehigh University (1882, $40,000), Cornell University (1882-83, $40,000), Tufts College (1882-83, $10,000), University of Wooster (1882-83, $4200), Johns Hopkins University (1883, $10,000), Amherst College (1883-84, $65,000), Bryn Mawr College (1884, $18,000), Dickinson College (1884, $8000), Lafayette College (1884, $15,000), and University of Minnesota (1884, $34,000). Twenty-five years later 114 institutions reported gymnasia, and in 1920 the number had increased to 209.[265]
