The radio wavelength luminosity of starburst galaxies correlates well with their star formation rates (Condon, 1992). Using this connection and three deep radio surveys, Haarsma and I constructed the global star formation history. Our results (see Haarsma et al., Ap. J., 2000 for details) show a steep increase from z = 0 to z = 1, matching calculations of the global SFR based on optical observations, when those observations have been corrected for the obscuration caused by dust. We note that our method requires no corrections for dust obscuration. We do, however, need to correct our results for radio emission from AGN. We do so using the extensive optical identifications available in these three fields.
