The GALLEX solar neutrino experiment, a big technological challenge, was the successful attempt to measure the fundamental pp-neutrinos and thereby to solve the long standing "Solar Neutrino Problem", namely a deficit in ~8B neutrinos established with the first ever operating solar neutrino detector, the Homestake Chlorine experiment of R. Davis jr. Here I recall in the historical context the GALLEX discovery of solar pp-neutrinos in 1992 and the first assurance of non-zero neutrino mass (most probably related to neutrino flavor oscillations) in 1995. GALLEX/GNO collected observational solar neutrino data at the Laboratori Nazionali del Gran Sasso (LNGS) from 5/1991 through 4/2003. I summarize the milestones of the project and connect them with some personal recollections.
