Giorgio Fiocco was found dead in the roof garden of his mother's house on 31 July 2012, with pliers and a screwdriver in his hands. He was apparently fixing the watering system for her flowers. The passion for laboratory work never left Giorgio, and his contributions to very different aspects of experimental geophysics will remain his most important legacy. Immediately after the invention of the laser, Giorgio was the first to demonstrate many applications using this technology. The most important was light detection and ranging (lidar), which is now one of the most important sounding techniques for the atmosphere. He pioneered the first Doppler lidar to measure wind and the development of a very long baseline laser interferometer to measure the strain rate of seismic faults or the detection of gravitational waves.
