The search for gravitational waves was initiated by Joseph Weber and continued with resonant detectors, first at room temperature and finally at cryogenic temperatures. These detectors reached a sensitivity able to observe gravitational waves generated by the conversion of 0.001 solar masses in the Galaxy. No clear signals due to gravitational waves have been observed with this technique, although intriguing results on the SN1987A were published. The search with resonant detectors, lasted four decades, has paved the way to more sensitive detectors, the long-arm laser interferometers.
