I need hints for a speech on my late principal's death anniversary ?? - what to say in a work anniversary speech

Our founder died - Principal and we will give a speech on the anniversary of his death. Can anyone give me some suggestions? It was a very sensitive person, who was a good friend for us as students. And it is a learned extremenly type - big heart, friendly, punctual to a fault, and a social worker.
