Syd King was born in Chatham in August, 1873. After being educated at Watford Grammar School he found work at an ordnance depot. A talented footballer, he played at right-back with Northfleet United in the Kent League. In 1897 he moved to New Brompton (Gillingham).
In 1899 Francis Payne, Thames Iron Works' secretary, was given the task of finding good players for the club's first season in the top division of the Southern League. According to one report, Arnold Hills, gave Payne £1,000 to find the best players available. Payne signed several players including King, who at the time was considered to be the most promising full backs in the country and Derby County, one of the best teams in England, challenged Thames Iron Works for his signature.
Over the next few years Syd King developed a good partnership with Charles Craig, a left-back from Dundee. Syd King suffered a bad ankle injury against Tottenham Hotspur on 10th March, 1899. This ruled him out for the rest of the season. King played 28 games the following season.
In the 1901-02 King was part of the highly successful West Ham United team that included players like Hugh Mounteith, Fergus Hunt, Freddie Fenton, George Radcliffe, James Reid, Albert Kaye, Billy Grassam, Charlie Dove, Roderick McEachrane, Fred Corbett, Walter Tranter and Charles Craig that finished 4th in Division 1 of the Southern League.

Syd King, who had received a very good grammar school education, was seen as more intelligent than most players and at the end of the 1901-02 season was appointed as club secretary/manager. He continued to play but injuries restricted his appearances and he retired from the game after playing against Kettering Town on 15th April, 1903. King had played a total of 89 games for the club.
West Ham United lost their prolific scorer, Billy Grassam, to Manchester United before the start of the 1903-1904 season. Dick Pudan, a local lad from Canning Town, who had played well at full-back the previous season, left for Bristol Rovers. He later went on to play for Newcastle United in the 1908 FA Cup Final.
Syd King brought in Charles Satterthwaite from New Brompton to replace Grassam. William Kirby, a right-winger who had a good scoring record, was signed from Swindon Town. Tommy Allison was brought in from Reading to bolster the defence. Herbert Lyon, a forward, also joined from Reading. Len Jarvis, a talented local boy, was also brought into the team.
Attendances at games, compared to their close rivals, remained disappointing. One reason for this was no nearby railway station. West Ham United began to verge on the edge of bankruptcy and by the end of the season the club only had had the money to pay the wages of one professional player, Tommy Allison, during the summer.

Arnold Hills was also having financial problems and was unwilling to re-negotiate a rental agreement to use the Memorial Grounds that was acceptable to West Ham United. The club was forced to find another sponsor. A local brewery agreed to advance them a loan to help them purchase a new ground.
Syd King was given the task to find West Ham a new home. It was suggested that he should take a look at Boleyn Castle field, just off Green Street, East Ham. The land was owned by the Catholic Ecclesiastical Authorities and used by the Boleyn Castle Roman Catholic Reformatory School.
A deal was arranged with the Catholic Ecclesiastical Authorities but the Home Office made it clear that they did not approve of the land being used by West Ham United. Syd King went to see Sir Ernest Gray, an influential Member of Parliament. As King later explained, "through his good offices, subject to certain conditions, we were finally allowed to take possession of Boleyn Castle".
The West Ham financial crisis meant that King was forced to sell Charles Satterthwaite and William Kirby. Satterthwaite, who scored 18 of West Ham's 38 goals, was transferred to Arsenal and Kirby returned to Swindon Town. West Ham also lost two of their most talented youngsters, James Bigden (Arsenal) and William Barnes (Luton). While Herbert Lyon, who scored two goals in his debut as centre-forward, was transferred to Brighton & Hove Albion. West Ham also lost their goalkeeper, Fred Griffiths to New Brompton. In two seasons with the club, Griffiths kept 13 clean sheets in 48 league appearances. Griffiths was replaced by another international goalkeeper, Matt Kingsley from Newcastle United.
Syd King also recruited Charlie Simmons (West Bromwich Albion), Frank Piercy (Middlesbrough) and Jack Fletcher (Reading). The most significant signing was David Gardner, a defender who had played at the top level for Newcastle United. A great favourite with West Ham fans, he was appointed captain of the side. King also introduced, Billy Bridgeman, a local teenager, into the side.
By the end of the season West Ham had climbed to 10th place in the league, scoring 48 goals in 34 games. Top scorer was Billy Bridgeman with 11 goals. Others who made a major contribution included Charlie Simmons (8), Jack Fletcher (7) and Christopher Carrick (6). West Ham also gave promising youngster, George Hilsdon, seven games, in which he scored 4 goals.
At the beginning of the 1905-06 season, Syd King recruited George Kitchen, a goalkeeper, from Everton. His most important signing was Fred Blackburn, who had such a good goal-scoring record at Blackburn Rovers that he had played for England against Scotland in 1901. Billy Grassam, who had been such a prolific scorer between 1900-04, returned to West Ham United after a season playing for Manchester United.
King also persuaded the highly experienced James Jackson to join the club. He had built up a good reputation as a tough-tackling full-back while playing for Glasgow Rangers, Newcastle United and Arsenal. Harry Stapley, a school teacher, who refused to become a professional player, was signed from local side, Woodford Town.
West Ham also lost the talented youngster, George Hilsdon, to Chelsea. He had been injured the previous season and while recovering he was seen by the Chelsea manager, John Robertson, playing for the reserves. He later wrote: "I never even set eyes on the player I went specially to see. They were glued all the time to the inside-left; a cockney lad, 19 years of age... If I get him he'll be our first team centre-forward next season."
Roberton's prediction was correct and Hilsdon went on to score 26 goals that season, and was a major factor in Chelsea's promotion to the First Division. Hilsdon also went on to play for England.
The loss of talented youngsters to league sides was a common story during the first five years of the 20th century. Other talented West Ham United youngsters who left the club during this period included William Barnes, Bill Yenson, James Bigden and Dick Pudan. The 1905 edition of Association Football included the following passage: "It is the proud boast of the West Ham club that they turn out more local players than any other team in the South. The district has been described as a hot-bed of football and it is so. The raw material is found on the marshlands and open spaces round about; and after a season or so, the finished player leaves the East End workshop to better himself, as most ambitious young men will do. In the ranks of other organizations many old West Ham boys have distinguished themselves."
West Ham had only a moderate season that year, winning only 14 of its 34 games. The Irons scored 42 goals against 39 conceded. The club also lost in the first round of the FA Cup against Arsenal. After a 1-1 draw at Upton Park that was watched by 18,000 spectators, Arsenal won the replay 3-2.
Syd King managed to bring in some useful looking players for the 1906-07 season. This included the Scottish international, David Lindsay, an outside right from from Heart of Midlothian. King also signed two defenders, Archie Taylor (Brentford) and Bill Wildman (Everton). David Clarke, who had formerly played for Bristol Rovers, was brought it as an understudy goalkeeper to George Kitchen.
West Ham looked a much better balanced team that season. The defence that included George Kitchen, Frank Piercy, David Gardner, Len Jarvis, Tommy Allison and Bill Wildman, only conceded 41 goals in 38 games.
West Ham also had a potent forward line that season. Harry Stapley, the goal scoring schoolteacher hit the net 22 times that season. His strike partner, Lionel Watson, added 12 more. Billy Grassam also returned to form with 10 goals. All told, West Ham scored 60 goals that season.
A local lad from Barking, Tommy Randall, also made his debut for West Ham against Fulham in the last game of the season. Fulham, who had already been crowned champions, lost the game 4-1. This result pushed the Irons into 5th place. This was the best season since they had finished 4th in the 1901-1902 season.
