Title: List of Glee characters
Content:  Lillian Adler (Jane Galloway Heitz) was the glee club director until 1997 when she died of unknown causes. She was the director of glee club when Will Schuester was a member. Adler first appears in the uncut version of the premiere episode, "Pilot", and her memorial plaque serves as inspiration for Will to take over as glee club director. Her plaque was viewed during the course of the series by Will and other glee club members as a further source of inspiration. The plaque resided in the choir room until the episode "100", when it was moved to the auditorium. Adler's final appearance is seen in a flashback by Will to the pilot episode in the series finale "Dreams Come True". The last scene of the series showed Adler's plaque alongside a plaque of the rededication to the auditorium and a memorial plaque for Finn Hudson.
