In February of 1943 three students created the school seal. The seal consists of four parts:

1. William Underhill drew a crown of thorns to represent endurance and the letter J to represent the Jesuit fathers
2. Robert Mullen designed the Lone Star surrounded by a laurel wreath to represent Texas and its honor and dignity
3. David O’Brien drew a cowboy on a bucking bronco to represent the early days of Texas industry
