  Here follow three reports covering different aspects of the early history
from 1964 to 1980 of the Hipparcos satellite mission. The first report
"Interviews about the creation of Hipparcos" contains interviews from 2017 with
scientists about how the mission was conceived up to the begin of technical
development. The second report "From TYCHO to Hipparcos 1975 to 1979" is about
the Hipparcos development based on new material from my archive. From my 65
years dedicated to the development of astrometry, I argue that very special
historical circumstances in Europe were decisive for the idea of space
astrometry to become reality: Hipparcos did not just come because
astrophysicists needed the data. The third report "Miraculous 1980 for
Hipparcos" documents how the approval of the astrometric mission in January
1980 in competition with an astrophysical mission was only achieved with very
great difficulty, even after an outstanding astrophysicist had presented
overwhelming arguments that the astrometric mission would be scientifically
much more important.
