Donald Simpson Bell V.C

Full back Donald Bell was on the books at Newcastle United as an amateur in 1910-11 but didn't make a first team appearance.
In 1913 he made his League debut for Bradford Park Avenue. He made 5 appearances for the club.
In 1916 2nd Lt. Bell was awarded the Victoria Cross. He was killed in action 5 days later.

During an attack a very heavy enfilade fire was opened on the attacking company by a hostile -machine gun. 2nd Lt.

Batey, rushed across the open under very heavy fire and attacked the machine gun,, shooting the firer with his revolver, and ‘destroying gun and personnel with bombs. This very brave act saved many lives and -ensured the success of the attack. Five days later this gallant officer lost his life performing a very similar act of bravery.

Apart from the city of Sheffield, Yorkshire was Rugby country. Professional Association teams began to emerge at the turn of the century, but public interest largely remained with Rugby. This is illustrated by the relative attendances in Huddersfield as late as 1919. Town's average attendance was around 4,000 whilst the Rugby club drew crowds of 10,000.
Sheffield of course held a  special place in the development of organised football (pre dating Association), and the emergence of 2 great clubs was a reflection of the huge popularity of the Association game in the city when the rules had effectively become unified.
Let's look at the League careers of the Yorkshire based clubs in the pre 1937 era:
