We report the magnetic trapping and evaporative cooling of bosonic and fermionic isotopes of atomic chromium. Using a cryogenic helium buffer gas, 10^12 chromium atoms are trapped at an initial temperature of ~1 K. The chromium atoms are then cooled adiabatically and evaporatively to temperatures as low as ~10 mK. Elastic and inelastic ^52Cr collisional cross sections are measured over this temperature range. Prospects for simultaneously creating a ^52Cr Bose-Einstein condensate and ^53Cr Fermi degenerate gas will be discussed.
