Robert "Bob" Piggott was the son of Fred and Emma Piggott and moved into 13 Coronation Street in 1902. Bob and his twin brother Vic signed up with the Lancashire Fusiliers in 1915. Some months later, the Piggotts received news that both of their sons had been killed when a bomb hit their dugout on the Somme. Bob first appeared in Daran Little and Bill Hill's "Weatherfield Life", published in 1992. Other information is derived from Little's follow-up book, "Around the Coronation Street Houses".
