John 'Jack' Biddulph Dold (January 3, 1902 - September 17, 1968) was a South African rugby union international and first-class cricketer with Eastern Province.
In six first-class matches between the 1922/23 and 1926/27 South African cricket seasons, four of them in the Currie Cup, Dold made 269 runs at 22.41 and took two wickets at the cost of 26.50 runs each.[1] He performed well on his debut, against the touring Marylebone Cricket Club, opening the batting and scoring 55 in his second innings.[2]
Dold, who was born in Grahamstown, played ten matches for the South African national rugby union team but no Tests. He was a member of South Africa's 1931/32 tour of Britain and Ireland and all of his matches came on that tour. A forward, Dold represented Albany at club level and Eastern Province provincially.[3]
