In this presentation we will discuss measurements of the longitudinal development of air showers at the Pierre Auger Observatory. The longitudinal development can be directly observed by the fluorescence telescopes of Auger and we will present the results on the evolution of the average of the shower maximum and its fluctuations as a function of energy. Moreover, two observables from the surface detector, the asymmetry of the rise time and the muon production depth, will be discussed and the measurements will be compared to predictions from air shower simulations for different primary particle types.
