I doubt whether any cricketer has been so consistently successful from the off of his career. After playing one match for Surrey in 1958 in 1959 he scored 1799 runs at 52 never looked back.
He was very brave too ..

Wisden overview
The youngest member of a prolific Norfolk cricket family, John Edrich was the sort of opening batsman every team-mate, and all selection panels, yearns for. A stocky left-hander of infinite discipline and courage, he knew his limitations and played to them unblinkingly, waiting for the right ball to put away. His main scoring areas were square on the off side, where he square-cut and punched either side of cover point with equal certainty, and through midwicket, where he was prolific. Years before batting helmets were even thought of, he was badly injured in 1965 when, following a sequence which brought him 1311 runs in nine innings, a triple-century against New Zealand, he ducked into a short ball from Peter Pollock, South Africa's fastest bowler of the 1960s. The ball seamed up the Lord's slope and hit Edrich on the forehead, knocking him cold. But as when Lillee broke two of his ribs at Sydney in 1974-75, it made no difference to Edrich's game at all: he just stayed in line and took whatever came his way. He was also a realist. On the rare occasions he was struggling for runs, he turned to Wisden to check how many runs he had made. "Twenty thousand, eh?" he would say to himself: "I can't be such a bad player after all!"

He made his Test debut against West Indies at Old Trafford in 1963 and finished against the same opposition on the same ground 13 years later.
The opener top scored with 24 in the second innings of his last Test in 1976 as England were bowled out for 126 by West Indies' formidable pace attack on an uneven pitch to lose by 425 runs.
His characteristic bravery was illustrated in that final Test innings at the age of 39 as he and opening partner Brian Close, 45, stoically defended for 80 minutes at the end of Saturday's play in the face of fearsome bowling by Andy Roberts, Wayne Daniel and Michael Holding.
Batting without helmets or chest protectors, Edrich was unbeaten on 10 and Close on one at the close and they took the score to 54 in the next day's play before the former was out for the final time in a Test - bowled by Daniel.
Close, bowled by Roberts for 20 soon after, also did not play for England again. They were the only England players to reach 20 in the innings.
