His son, John B. Wornall II, and later a grandson, John B. Wornall III, attended Jewell. Each served as trustees of the institution. Wornall Hall, a 3-story brick structure of pleasing design, was built four years after the death of the senior Wornall and housed the president's office and science laboratories on the first floor, classrooms on the second and a large auditorium on the third. It was William Jewell's first auditorium. The building was destroyed by fire in 1913, the year the old post card above was mailed from Liberty.
Lightning is believed to have been the cause of the fire.
Gano Chapel, dedicated in 1926, was built almost over the spot where Wornall Hall had stood, on the brow of the hill. It remains in use today.
