Colonel John Dale Lace (27 November 1859 – 5 June 1937) was a South African gold and diamond mining magnate and Randlord.
It is believed that she was proposed to by Cecil John Rhodes, prime minister of the Cape at the time, and was mistress to King Edward VII.
The Dale Laces were owners of one of Johannesburg's most prominent historic landmarks, the Parktown mansion 'Northwards', designed by British architect Herbert Baker in 1904.
Just as the gold-mining industry was booming, the diamond market was being monopolised by De Beers, which went on to become the world’s largest diamond company - the dissipation of the Dale Lace fortune coincided with a devastating fire at 'Northwards', and in 1912, the charred remains of the house were sold to George Albu.
John Dale Lace lost his fortune and he and José went to live at Boschkop (now Randpark Ridge), northwest of Johannesburg.
