Ebenezer Cobb Morley was the first secretary of The Football Association, its second ever president and the man who drafted the FA's laws of the game at his home in Hull. The world's first ever inter-club match took place on 26 December 1860 in Sheffield; the match was between Sheffield F.C. and a newly formed club named Hallam F.C.; Sheffield won 2–0. As Hallam were also from the city of Sheffield, this would also prove to be the world's first ever local derby in club football.
