The early history of gravitational wave detection in Italy.
La Rana A.
In the early 70s, two experimental activities for gravitational-wave (GW) detection were being carried out in Italy: one in Frascati, at the European Space Research Institute (ESRIN), performed by Karl Maischberger and Donato Bramanti; the second one set up by the group of Edoardo Amaldi and Guido Pizzella at the University of Rome. This second activity pioneered the field of cryogenic resonant bar detectors, which dominated Italian research on GWs until the 90s, when the French-Italian project for a giant interferometric detector came into life: Virgo, lead by Alain Brillet and Adalberto Giazotto.
