Broad stellar emission lines have been detected in the optical spectrum of a small cluster in the post-starburst galaxy NGC 1569. These lines, He I 5876, hydrogen alpha and He I 6678, have a full width at half maximum of 600 km/s, and are attributed to a late-type WN star. The cluster, located in the outskirts of the galaxy, is surrounded by a large (radius = 30 pc) ring nebula. This detection of a Wolf-Rayet star is a direct evidence of recent (less than or equal 5 Myrs) massive (Mi greater than or equal to 40 solar mass) star formation in NGC 1569.
