Harnisch Bernd - 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 and should not be considered as a list of currenly active people on the Gaia mission. 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 overview papers (for Gaia Data Release 1 see here, for Gaia Data Release 2 see here, for Gaia Early Data Release 3 see here, for the full Gaia Data Release 3 see here, for Gaia Focused Product Release see here). A history of contributions to the Gaia mission can be found from the acknowledgements given with each data release.

Bernd Harnisch is an optical engineer within ESA's technical directorate. He is closely involved in the development of the optical systems for Gaia, as technical officer for the development of the silicon carbide optics for Gaia (mirrors and payload structure) and for the high-stability optical bench/basic angle monitoring study. In these areas he works closely with the Gaia study manager in ESA, Oscar Pace, and supervises and directs the related industrial studies.
A prototype primary mirror (1.4 x 0.5 m in size) has been manufactured in SiC during the technology study phase (2002-04). This very challenging aspheric off-axis mirror has been manufactured in the Boostec facilities, polished, silver coated, and subject to environment testing and thermal cycling.
Bernd left Gaia in 2006.
