Alberto Lesarri gave a historical talk at the Faculty day last November 13, 2014. The talk explored the origins of the Faculty of Sciences in the period 1857-1923, associated to the important social and political changes of that time. The picture below shows the Main Hall (“Paraninfo”) of the University ca. 1925’s, later demolished. The talk is freely available.
The motto on the left of the wall is “Vitam impedere vero” (“to devote life to truth”). The cross marks the former dean Arturo Pérez Martín (Source: APM family).
