Alan and Michael are twin brothers, sometimes referred to either as the Perry Brothers or the Perry Twins, who were born in 1961 and brought up in North London. They have played wargames since the age of 10, and are avid collectors of antique armour, weapons and other militaria. They studied Art at A-levels, and started sculpting freelance for Games Workshop in 1978, while still in school. They joined the company in 1980, and were the longest-serving members of the Games Workshop Design Studio.
