Tom Crean was born in 1877 in Ireland and left school at age 12 to work on his family's farm. At age 15, he ran away and joined the Royal Navy, where he spent the next eight years traveling the world. In 1901, he volunteered to join Captain Robert Falcon Scott's expedition to Antarctica, where he proved his strength and resilience. Crean went on to participate in two more Antarctic expeditions, displaying great heroism by making a solo trek to save his companions and later searching for Scott and his team after they perished reaching the South Pole.
