New NTT/SOFI near-IR narrow-band imaging and spectroscopy reveals an additional four Wolf-Rayet (WR) stars in the massive cluster Westerlund 1, bringing the total WR population to 24. Sixteen of the WR stars in Wd1 have been classified WN5--11, while eight are WC8--9. An observed WR to RSG/YHG ratio of ˜3 suggests an age of 4.5--5.0 Myr, with WR stars descended from 40--55Msun progenitors. On the basis of dust and hard X-ray emission, we estimate that 40--65% are probable members of massive star binary systems.
