John Tait Robertson

John 'Jacky' Tait Robertson (25 February, 1877 in Dumbarton – 24 January 1935) was a Scottish football player and manager.

Robertson was a central defender whose career included brief stints at Everton and Southampton before moving to Rangers, where he won three consecutive Championships. He was also a Scotland international, winning 16 caps between 1898 and 1905 and scoring 2 goals, both of which came against Wales.

In April 1905, Robertson became the first ever manager of the newly-formed Chelsea Football Club but continued to play as well. It was Robertson who scored Chelsea's first competitive goal, in a 1-0 win at Blackpool. In his first season, he led the club to a third place finish in the Second Division. He then surprisingly resigned from the club (third in the table at the time) on 27 November 1906. Chelsea were promoted to the top flight at the end of that season under caretaker secretary-manager William Lewis. Soon afterwards Robertson became player-manager of Glossop, where he remained until summer 1909, when he became reserve-team manager at Manchester United.

He died in Wiltshire in January 1935.
