Women in science, technology, engineer and math or STEM have met many challenges. There are a number of blockades that they encountered throughout their education and professional lives, with some disciplines being more problematic than others.
It took Elsie a long time to come to terms with the idea that there was discrimination within engineering, in part because she had never really stopped to assess her own experience.
