Last October 28 and 29, Mozaika organized the HerStories Seminar at its headquarters, Casa Adret. Over two days, 30 passionate teachers from all over Barcelona came together to learn first-hand about the educational possibilities offered by the HerStories project. Over the course of two very intense days: the project was presented; the question of why it is important to approach History from a gender perspective was addressed, especially using personal testimonies; the 7 HerStories were revealed; Google Classroom teaching material was shared, carrying out one of the proposed activities; Dory Sontheimer - Rosl's daughter - told the story of her mother; Stefania Fantauzzi spoke about Hannah Arendt; there was a walking tour following Rosl's footsteps through the streets of Barcelona, and finally, Daniel Voskovoynik, left attendees speechless with his passionate approach to Jewish music background.
