Bradley lived at York Road in Market Weighton from his birth in 1787 to his death in 1820.
At 7ft 9in, he was the tallest Englishman ever recorded, the fourth son of a family of 13. His father John was 5ft 9in, and his mother Ann was of average height.
His brothers and sisters were of normal size, except one sister who would have been nearly as tall as William had she not died at 16.
He weighed 14lb at birth and by the age of 11 he was 11 stone. At school his teacher used to make him lift naughty classmates and leave them clinging to the crossbeams of the ceiling until he decided they had enough.
At 19 he weighed 27 stone and measured 7ft 8in. A year later he had grown another inch.
Bradley, who became known as the Yorkshire Giant, made a small fortune as a fairground freak, but confinement in a travelling caravan was bad for his health and later he organised his own more dignified shows.
At Windsor he was presented to King George IV, who gave him a massive gold chain which he wore until the day of his death.
When he died aged 33, he was buried inside the church for fear of graverobbers.
His presence is recorded on a wall outside his old house, with a memorial tablet recording the size of his footprint.
After Bradley had all but faded from memory, a small band of townspeople set to work a decade ago to raise his profile and now hold an annual Giant Bradley Day.
