The aim of the study is to analyze the careers of women gymnastics directors about the turn of the century in 1900. This is done by means of a collective biographical study of the women's course at the Royal Central Institute of Gymnastics in Stockholm from 1891 to 1893. The study is based above all on unique correspondence between the members of the course, namely a correspondence book circulated among them between 1893 and 1943. This book contained a total of almost 500 letters comprising thousands of handwritten pages with detailed accounts of their professional career and family, as well as life's positive and negative sides. The study shows that their opportunities of making a career in Sweden and abroad in the occupation they had received training in were good. There are several reasons for this success. Swedish gymnastics treatment methods were the height of fashion round about the turn of the century in 1900 and there was great demand for their services. They remained faithful to their choice of occupation, even if their career took a back seat for half of them when they married: family life and a professional career could not be combined for them.
