Who was the first cricketer to hit six sixes in a single over?

Sir Garfield St Aubrun Sobers also known as Gary or Garry Sobers, is a former cricketer who played for the West Indies between 1954 and 1974, and is widely considered to be cricket's greatest all-rounder.

On 31 August 1968, Sobers became the first batsman ever to hit six sixes in a single over of six consecutive balls in first-class cricket. The feat consisted of five clean hits for six and one six where the ball was caught but carried over the boundary by Roger Davis. Sobers was playing as captain of Nottinghamshire against Glamorgan at St. Helen's in Swansea; the unfortunate bowler was Malcolm Nash. This tally of 36 runs in an over broke a 57-year-old record of 34 runs, held by Ted Alletson. The ball was collected from a garden by 11-year-old Richard Lewis; he later gave the ball to Sobers. In 1984–85, Indian batsman Ravi Shastri equalled the record by scoring six sixes in an over while playing for Bombay versus Baroda.

In a normal over, a single bowler delivers six balls in succession, from one end of the pitch, to the batsman at the other end. The highest amount you can score off a delivery is six when the ball is hit over the boundary line. Therefore six deliveries in an over all hit for six runs each will give a maximum total of 36 runs.
