He was a member of the Surrey side that won the County Championship in 1971, and also played for Western Province in South Africa in 1971–72, and for Rhodesia between 1972–73 and 1979–80.
Jackman was born in the northern Indian hill town of Shimla on 13 August 1945 where his father, a major with the 2nd Gurkha Rifles, was stationed.
[4] At 5 ft 9in tall, he was comparatively short for a seamer, and some felt he would struggle to prove himself at first-class county level, but Jackman worked hard to extract the absolute maximum from his talent, spending winters practising in South Africa.
[8] He became known for his wholehearted effort, his long, trundling run-up and side-on delivery action, and for his theatrically fierce and loud appealing for wickets.
[2] Jackman was given the occasional outing by England in one-day internationals from 1974, but Geoff Arnold, Bob Willis, Chris Old and others kept him out of the Test side.
[9] At last, in 1980, it seemed likely that he might get a Test call-up as he finished the season with 121 first-class wickets (20 more than any other bowler), aided by the much improved pitches at The Oval and having a very ferocious new ball partner in Sylvester Clarke.
[12] But the England selectors, choosing a squad to tour West Indies in the winter of 1980/81, showed reluctance to pick a seamer who was by now 35 years old, and only placed him on the reserve list.
Bateman added "a magnificent trier with a theatrical appeal, Jackman was a fine county fast-medium bowler who finally had his England chance".
They would go on to marry in England, living in Bisley, Surrey for many years prior to relocating to South Africa after his retirement from playing cricket.
[26] He died at his home in Cape Town on 25 December 2020, after lung and heart complications and testing positive for COVID-19 4 days earlier.
