Among the technical and scientific studies, the evolution of the computer sciences draws attention. From the 1980s, in France, more and more men have chosen this field but in the same time, the number of women has remained the same. By studying computer scientists' discourses and questionnaires completed by first-year science students, we observe the computer scientists' image has changed in the past 30 years. Before the micro-computer, ICT jobs were service industry scientific jobs. They were quite attractive to female scientists.
