Just a year after stunning the football world by paying £1,000 for Alf Common, Boro pulled off another sensational coup by recruiting this established England international and one of the finest goalscorers of his generation.
Though slight in build and bearing a complexion that prompted the nickname 'Paleface', Bloomer shook off the uncompromising tactics of defenders and had the touch and skill to excel in his forward role.
Goalscoring was his biggest asset, and Bloomer went on to set a contemporary record of more than 500 first class goals. He was Boro's top scorer in 1906/07 and 1907/08 as the club put relegation battles behind them to cement our place in the First Division.
Returning to Derby in 1910, Bloomer continued his goalscoring exploits and cemented his legendary status with The Rams - a bust of the striker now has pride of place, pitch side at Pride Park.
After retiring as a footballer he became a coach and worked with clubs in Germany, the Netherlands and Spain.
During World War I he was interned at Ruhleben, a civilian detention camp.
He is also listed in the Football League 100 Legends and English Football Hall of Fame.
