A list of 50 bright Detached Eclipsing Binaries proposed for precise parallax measurements for the FAME is presented. The eclipsing binaries, with precise distances and with photometric and double-line spectroscopic orbits determined, are essential for a full calibration of relations that could be used for very precise distance determination of globular clusters, LMC, SMC, and perhaps also M31 and M33.
The parallaxes determined by Lacy (1979) by means of eclipsing binaries method are compared with the Hipparcos parallaxes for 19 systems. The residual scatter of the distance moduli inferred from eclipsing binaries method - after allowing for known errors as given by Lacy and Hipparcos - is equal to 0.18 mag. It decreases to 0.08 mag when obviously not fitting semi-detached systems and systems with chromospheric activity of components are removed from the sample.
