1877 Wimbledon Championship [SEP] Introduction
The 1877 Wimbledon Championship was a men's tennis tournament held at the All England Croquet and Lawn Tennis Club (AEC & LTC) in Wimbledon, London. It was the world's first official lawn tennis tournament, and was later recognised as the first Grand Slam tournament or "Major". The AEC & LTC had been founded in July 1868, as the All England Croquet Club; lawn tennis was introduced in February 1875 to compensate for the waning interest in croquet. In June 1877 the club decided to organise a tennis tournament to pay for the repair of its pony roller, needed to maintain the lawns.
