   Presentation.Abstract:
   	A teenager, Bengt Strömgren, made an astrometric experiment
   	in 1925 which had wide- reaching consequences. The direct
   	connection from Strömgren's photoelectric recording of
   	stellar transits on the old meridian circle in Copenhagen
   	to the Hipparcos and Gaia space missions is presented in
   	the lecture. Peter Naur was astronomer and Høg was his
   	student and collaborator 1953-58 and very interested in
   	techniques.  Working in the Hamburg Observatory from 1958-73
   	Høg invented and developed a semi-automatic meridian circle
   	for an expedition to Perth in Western Australia and a GIER
   	computer went with it. With this experience he could make
   	a new design of an astrometric space mission in 1975 which
   	developed into the Hipparcos mission.
