We observed four OB associations in the Large Magellanic Cloud which contain Wolf-Rayet stars. The associations are located in the neighbourhood of 30 Dor. They contain 15 WR stars of WCE and most WN subtypes. The observations include UBV photometry for several thousand objects and spectroscopy in the range from 3500 to 5000 Å for about 250 stars. Two new extreme Of stars and a new WR star as well as many hitherto unknown O stars were identified. Cluster HR diagrams reveal the age structure of the association stars and yield tentative conclusions about evolutionary connections between Wolf-Rayet stars in the LMC.
