Nov. 22 (UPI) -- Jane Galloway Heitz, a television actress who appeared on Glee and worked as a casting agent, has died at the age of 78.
Galloway Heitz appeared as Lillian Adler on Glee, the former head of the glee club at McKinley High. A photo of Adler was famously displayed in a trophy case at the school with the quote "By its very definition, glee is about opening yourself up to joy."
