Deepest sympathies to the Seidel family. Mrs. Seidel was an amazing person and teacher. My brother, sister, and friends have wonderful memories of her. She always listened to my stories of being a Letterman fan, as I know her husband worked for CBS. We remember her 3 hole punch paper, having us keep binders for class, and always washing her chalkboard. We even remember some atomic numbers to this day! May she rest in peace and her family be strong in this time.
