The contributions of women in the different fields of scientific knowledge have been unknown in the official history of the sciences. This is evident when it is asked about the presence of women in science, which is generally dismissed by the hegemonic male model. This model assumes that science is an objective, neutral and universal construction that offers the same possibilities of getting involved and development in the field to all its practitioners, regardless their gender, age, race, religion or political party affiliations. This situation is particularly true for the Colombian case since, added to the structural barriers that limited access to women professional development in certain fields of knowledge, the process of institutionalization of scientific disciplines is very recent. Because of this, the stories of science in Colombia that have been written have hidden in the shadow of the ‘founding fathers’ the contributions that women scientists have made to the field of science. In this sense, at first, from the framework of social studies of science, a historical sociological approach to the institutionalization of chemistry in Colombia is presented in this paper. In a second moment, the contributions to the field of Colombian chemistry made by Dora Turk Molano, one of the first two female chemistry graduates in this country, whose presence and contributions have not been considered by the official history of Colombian chemistry, are discussed.
