Seyfert 2 nuclei appear to live in galaxies with an elevated rate of star formation compared with field galaxies or the host galaxies of Seyfert 1 nuclei. It is not clear what causes this difference. The elevated star formation might be associated directly with the feeding of matter into the AGN, with the Seyfert 2 galaxies revealing a particular stage in this process that Seyfert 1s are not currently in. Alternately, the elevated star formation might arise from a common trigger -- for example, an interaction with another galaxy -- that establishes an axi- symmetric potential to feed the AGN and also initiates elevated star formation in the galaxy. Again, the difference between Seyfert 1s and 2s might indicate a different stage in this process. To test these possiblities, we have selected a complete sample of 17 Seyfert galaxies with strong star formation and which can be well resolved by ISO. We have determined the specific observations required to resolve these galaxies that are NOT included in the guaranteed time and we propose to obtain these data. This proposal roughly doubles the number of galaxies in our sample that ISO will resolve, and will provide enough examples to determine the typical proximity of the regions of elevated star formation to the active nuclei.
