I had not heard of Mr. Young until continuing to read through the tribute blog of stars who died in 2025. Paula Shaw: "Shaw had a recurring role as Mrs. Byrne in the 2011-2013 YTV sitcom Mr. Young. The series centers on Adam Young (Brendan Meyer), a child prodigy who graduated from university at the age of 14. Mrs. Byrne is an elderly, clueless history teacher who is in charge of the science club and school newspaper. It also starred Matreya Fedor, Gig Morton, Kurt Ostlund, Milo Shandel and Emily Tennant."

The epguides.com description: "A child prodigy, who feels that he missed out on the normal social experience of high school, graduates from college at 14 and goes back to his former school as the science teacher."

Young Sheldon had not been created yet, but The Big Bang Theory was a few seasons in with the Sheldon portrayed by Jim Parsons.
