He is credited with having founded the Royal Engineers Football team in 1869, which went on to win the FA Cup in 1875. The club had been founded in at least 1863 and is notable as the first side to exploit modern teamwork and passing tactics. He retired from the Royal Engineers in 1879 at the rank of Major. As a football player, Marindin played in the first FA Cup Final in 1872, which the Royal Engineers' team lost to Wanderers. At the time, Marindin held the rank of Captain. The team lost the Final again, to Oxford University in 1874 with Marindin in the XI, but won it against the Old Etonians F.C. in 1875, although Marindin was absent, having left Chatham for a new posting. Marindin become the President of the Football Association in 1874 and served in that capacity until 1890. As a referee he took charge of the 1880 FA Cup final and seven in succession from 1884 to 1890. This period included a replay at Derbyshire County Cricket Club's Racecourse Ground in 1886, the first time an FA Cup Final had been played outside London. In his last final, crowds invaded the pitch and soldiers had to clear the field. He was considered "one of the outstanding referees who really knows the rules". He was widely known simply as "The Major".
Later career
He became an Inspecting Officer for the Board of Trade in 1875, rising to Senior Inspector of Railways in 1895. His work in this regard involved travelling the country to test and inspect new works on passenger railways to ensure their safety before they could be used. In describing this period of his life, his obituary in The Times of 24 April 1900, described him as "plain speaking, coupled with a complete mastery of his subject", making the point that the railway companies of the time knew that his office "was not likely to allow irregularities to remain long unnoticed". In 1899 he submitted a report on accidents on railway workers on which a new Act of Parliament concerning rail safety was based, and throughout the 1890s was responsible for a host of improvements in the working practices of Britain's railways. He helped develop London's new electrical lighting system and was knighted in 1897. He died aged 61 on 21 April 1900 at home at Hans Crescent, London S.W., and was buried on the family Scottish property at Craigflower, Torryburn, Dunfermline.
