Henry Lockett played for Bolton Wanderers and Nottingham Forest when the two clubs were relegated from the top-flight in successive seasons. Yet, with nearly forty Division One appearances over the preceding two seasons it was quite a coup for Southern League Exeter City when he arrived at St James’ Park ahead of the 1911/12 season. Playing seventy league games in two seasons he joined Chesterfield in 1913.His first club after leaving school in 1897 was Cheshire-based Wilmslow. After a season-and-a-half, he was signed on professional forms by Crewe Alexandra staying for two years and helping the club win the Birmingham League and the Cheshire Cup. From Crewe he moved to Whitchurch in the Cheshire Combination, but after less than half-a-season he was rewarded with his first chance with a Football League club when signing for Bolton Wanderers. He went on to feature in 16 league matches for the Trotters (scoring four goals) before moving to Nottingham Forest in time for the 1910/11 season. Starting in the first team, he scored five goals in 23 matches but then lost his place and at the end of the season was released to join Exeter City.
He made his Grecians debut in a goalless draw at Watford in September 1911 and eventually ended the season with six goals in 34 Southern League appearances. The following season he played most of his games as a wing-half, a position he had filled whilst a schoolboy, missing just two matches for Exeter.
Leaving St James’ Park, he signed for Chesterfield before the suspension of football for the First World War. On the resumption after the war, he linked up with Stalybridge Celtic and scored one goal in 70 Football League outings until leaving the club in 1923 at the age of 43.
