François Henri Cornet was Emeritus Professor at the Institut de Physique du Globe de Strasbourg, France and the author of the book "Elements of Crustal Geomechanics." Sadly, he passed away suddenly on May 23, 2020 in Strasbourg. He was well known to the ARMA community and was the MTS keynote speaker at the 2017 ARMA symposium in San Francisco. He was a PhD advisor, close colleague, and friend to many of us, and will always be remembered as a passionate leader and mentor with a big voice and laugh, always ready to engage in scientific discussions and a true expert on stress field evaluation. Among other things, he was the main inventor of the HTPF (Hydraulic Testing of Pre-existing Fractures) method for full stress tensor determination. At the time of his passing, he was working on his second book with co-authors called "Stress and stress fields in geomechanics." In this paper, we revisit François's main scientific contributions to the geomechanics and geophysics communities. His main research interests spanned many topics: hydraulic fracturing and in situ stress measurements, understanding and modeling of regional stress fields, induced and natural seismicity, rock-fluid interactions, development of new observations techniques, advocate of large scale natural geophysical laboratories (e.g., Le Mayet-de-Montagne, Soultz-sous-Forêts, Tongonan, Corinth Rift Laboratory, nuclear waste disposal and carbon storage sites), and new modeling techniques for volcanology.
