Stanley Jackson, the Yorkshire amateur known to readers of the Wisden almanack as 'F.S. Jackson' or simply 'Jacker', had been a Test cricketer since 1893 but had never previously captained the side. By 1905 he was 35, a Conservative MP, and one of the senior figures in English cricket. He was appointed for the home Ashes series ahead of Archie MacLaren and Plum Warner, both of whom had previously led.
What followed was one of the most personally complete captaincy seasons on record. Jackson won the toss in all five Tests — beating his university friend Joe Darling each time. England won the second Test at Lord's by 282 runs, drew the rest, and won the series 2-0 to retain the Ashes. Jackson scored 492 runs in the five matches at 70.28 — top of the averages on either side — and took 13 wickets at 15.46, also top of both sides' bowling averages.
His individual scores included 144 not out at Headingley, 113 at Old Trafford, 82 not out at Trent Bridge, and 76 and 31 at The Oval. The 144 not out remains one of the most highly regarded of all Headingley innings, played on a difficult surface against an Australian attack of Cotter, Armstrong, Noble and Laver. Jackson never played another Test after the 1905 series; he could not spare the time to tour, and his political career took precedence.
