This study connects to gender research within the S&T-field (Science and Technology). As part of a big gender project at the university we wanted to meet those women who had started strongly male-dominated engineering educations at the university and try to find out why they had chosen these programs. The experiences and feelings of the women from childhood and adolescence were best caught with the qualitative research interview method. A very clear picture emerged about the professions of the fathers. Almost all were engineers or had employments where skills in technology were necessary. The women described the fathers as the most important person who had encouraged them to test different technical stuff and given them interest in technology during childhood.  Other male relatives have influenced the girls much more than the mothers and often in the same way as the fathers. Interestingly no women reported of female relatives who have stimulated interest in science and technology other than their mothers. Besides these hands-on experiences an early interest in mathematics and logical thinking is striking for these women. Mathematics seems in many cases to be the gateway to further studies within the S&T-field. It is important to offer young girls without those here described beneficial conditions opportunities to take part of corresponding milieus. Examples of such could be Science centers, technical and science museums and summer camps.
