This book that gathers the activity of Workshop 99 since its creation in 1956, the leading work of Nemesio Antúnez, who aimed to share with the trained artists the main knowledge acquired in France and deepen the different engraving techniques. With the passage of time, the teachings of the workshop expanded to cover all the techniques of engraving and different experiments of the artists, since Antúnez had the good idea of ??creating his workshop with an integrative perspective, which embraced the most varied styles and production techniques that maintain a connection with engraving. In this way, a versatile artistic scene could be configured. On the other hand, through teaching at the School of Art of the Catholic University the workshop influenced the formation of generations of students in the area of ??stamping, developed new methodological strategies for the transmission of knowledge in the area, and contributed Notoriously to the profile of this new school. Likewise, the influence of Workshop 99 was decisive in the recognition of engraving as a specialty option in conjunction with painting and sculpture, and installed Chilean engraving on the international stage opened by biennial engraving. In the context of the 60th anniversary of Workshop 99 of Engraving, the authors address the task of reconstructing their history from the testimonies of many of their founders, artists who have passed through it and current members, aware of the urgency of rescuing a past that could be forgotten and that is part of the memory of Chilean art.
