Henriette Lapierre passed away unexpectedly in January 2006 while on a field trip with close friends of hers in Syria. The aim of the trip was to sample Triassic and Jurassic volcanic rocks similar to those already studied in the Himalaya, Oman, Cyprus, Greece, Albania and Turkey. True to her convictions, the work was based on a team effort. Indeed, Henriette always insisted on the importance of teamwork to which she contributed her enthusiasm and extensive knowledge of petrology, mineralogy and geochemistry of volcanic rocks. This was the domain in which she excelled.
