According to popular belief, the use of the numbers 143 to mean "I Love You" dates back to 1915, when Winfield Scott Thompson was the keeper at Minots Ledge lighthouse, off the coast of Cohasset and Scituate, Massachusetts (to the southeast of Boston Harbor). The lighthouse flash sequence was 1-4-3, and Thompson's family could see the light flashing at night. Thompson's wife told their children that it was the "I Love You flash," their father's way of saying he loved them. The tale has proven so popular that the Minots Ledge lighthouse is nicknamed the "I Love You Lighthouse."
