  Near infrared images of the Galactic giant HII region W43 reveal a dense
stellar cluster at its center. Broad band JHK photometry of the young cluster
and K-band spectra of three of its bright stars are presented. The 2 micron
spectrum of the brightest star in the cluster is very well matched to the
spectra of Wolf-Rayet stars of sub-type WN7. Two other stars are identified as
O type giants or supergiants by their NIII and CIV emission. The close spatial
clustering of O and the hydrogen WN type stars is analogous to the intense star
burst clusters R136 in the Large Magellanic Cloud and NGC3603 in the Galaxy.
