Söderhjelm Staffan - Gaia
Gaia was proposed in 1993 and since then, many people have been involved in the Gaia mission, whether at ESA, at industry side or at one of the institutes involved in the Gaia data processing. The Gaia Data Processing and Analysis Consortium (DPAC) is a collaboration which consists of around 450 scientists and engineers.
The list of Gaia contributors presented here should not be considered a complete representation of the entire consortium. A more complete list of Gaia contributors that were involved in the creation of the Gaia catalogues can be obtained from the author lists of the Gaia Collaboration papers (for Gaia Data Release 1 see here, for Gaia Data Release 2 see here, for Gaia Early Data Release 3 see here). A history of contributions to the Gaia mission can be found from the acknowledgements given with each data release.

Staffan Söderhjelm has worked for a long time at Lund Observatory, Sweden. He has been involved in space astrometry since around 1980, and he worked extensively on the double-star reductions for Hipparcos. Continuing this interest, he has been working mainly in the Double and Multiple Stars and the Simulations Working Groups for Gaia, investigating the possibilities and problems posed by non-single stars. This is done by building models both of a Galaxy with binaries, and of the observations and reductions proposed for Gaia. Staffan likes to be known as that guy repeating all the time 'most stars are binaries'!
He left Gaia in 2006.
