Eigil Friis-Christensen †
Eigil Friis-Christensen passed away on 21st September 2018 after severe
	illness.
Eigil had tremendous impact as a scientific leader, working tirelessly
	throughout his career to promote interdisciplinary approaches and
	international collaboration. His scientific achievements include
	ground-breaking studies of the interaction between Earth’s magnetic
	field and the solar wind, in particular using data from the Greenland
	magnetometer chain that he initiated and installed in the 1970s; the
	Oersted and Swarm satellite missions to explore Earth’s magnetic field,
	and investigations of the connection between global temperature and the
	length of the solar cycle.
	
	He was highly regarded and recognized internationally for his many
	achievements. To list just a few: In 1997 he initiated the "Decade of
	Geopotential Field Research" within the IUGG, between 2007 and 2011 he
	served as president of IAGA, in 2009 he was awarded EGU’s Petrus
	Peregrinus Medal for "his fundamental contributions to our knowledge of
	the Earth’s magnetic field from space and his innovative leadership in
	geomagnetism" and also was elected a fellow of the AGU for "his
	pathbreaking cross-disciplinary scientific research and multi-national
	leadership in initiating new space-based research missions".
	
	Eigil's quiet and kind personality, combined with his dedication to
	science and his ability to inspire his younger colleagues and promote
	their individual careers, will be remembered by all who had the
	privilege to work with him.
	
	We have lost an outstanding scientist and a remarkable person.
