Bartholomew Bretherton (1812–1866) was a jockey from Maghull, north of Liverpool who rode many times in the Grand National as an amateur rider, winning the race in 1840 in the colours of Henry Villebois on his horse Jerry.
Bretherton's father and older brother Peter (second child and first son of Francis) were credited with starting horse-racing at Maghull Meadows, the precursor of Aintree Racecourse, in the late 1820s and 1830s.
He did not however lodge any protest on his return to the weighing room, suggesting that the act was considered part of the game.
As the horses increased their speed, Bretherton opened the door, climbed out onto the roof of the coach and over the box seat down upon the pole.
[3][4] A newspaper article in 1851 describes a pair of jockey top boots which were made for him in Liverpool and weighed only five ounces.
