1877 Wimbledon Championship [SEP] All England Croquet and Lawn Tennis Club
The All England Croquet Club was founded on 23 July 1868 by six gentlemen at the offices of "The Field", a weekly country and sports magazine. After a yearlong search a suitable ground of four acres of meadowland was located between the London and South Western Railway and Worple Road in Wimbledon, then an outer suburb of London. The club's committee decided on 24 September 1869 to lease the ground and paid £50 rental for the first year, a fee which increased to £75 and £100, respectively, over the following two years. The increasing rent, coupled with a waning interest in the sedate sport of croquet, was causing the club financial difficulties.
