We give an overview of past and present efforts to make seismology of delta Scuti and gamma Doradus stars possible. Previous work has not led to the observational detection and identification of a sufficient number of pulsation modes for these pulsators for the construction of unique seismic models. However, recent efforts including large ground-based observational campaigns, work on pre-main sequence pulsators, asteroseismic satellite missions, theoretical advances on mode identification methods, and the discovery of a star showing simultaneous self-excited delta Scuti and gamma Doradus oscillations suggest that we may be able to explore the interiors of these pulsators in the very near future.
