The Herbig Ae/Be stars are intermediate mass pre-Main Sequence stars evolving towards the Main Sequence to become A or B stars. They have gained a lot of interest over the last years because they prove to be excellent laboratories for proto-planetary disk and planet formation. In addition, by virtue of their intermediate masses, they provide an important opportunity to study the links between low mass star formation and the less well-understood formation of massive stars – an important class of objects in its own right. In this presentation I will give an overview of the class as a whole, present recent results on Gaia, and discuss the accretion rates and other properties as function of mass. The picture that emerges is not only that the higher mass Herbig Be objects can act a proxy for the elusive class of optically invisible Massive young Stellar Objects, but also that the T Tauri phenomenon extends to higher masses than previously thought. I will end by showing results on discovering new objects in the Gaia database using Machine Learning Techniques.
