His exact height is of some conjecture, but most accounts refer to him as from 8 feet 2 inches (248 cm) to 8 feet 4 inches (254 cm) tall, however true and undeniable skeletal evidence pitches him at just over 7 feet 7 inches. At the age of 21 he left his home in Littlebridge, Ireland and traveled to London to seek his fortune. He found work at Cox's Museum, an establishment not unlike P. T. Barnum's American Museum. He moved in next door in an elegant apartment with custom-built furniture at the cane-shop, in Spring Garden-gate.
He soon became the toast of the town, a May 6, 1782, newspaper report bears out: "However striking a curiosity may be, there is generally some difficulty in engaging the attention of the public; but even this was not the case with the modern living Colossus, or wonderful Irish Giant".
