Born in Darmstadt, Hesse, Wernher was the son of a railway engineer of Protestant stock. He was educated at Frankfurt-am-Main, where he entered a merchant bank. In 1871, having served in the Franco-German War, he moved to London at the age of 21. His talent for business was spotted by a diamond dealer named Jules Porgès of London and Paris, who sent Wernher in 1873 as his agent to the diamond mines of Kimberley, South Africa to buy and export diamonds. Wernher bought up mining interests and by 1875 was a member of the Kimberley mining board. In that same year, Porgès and Alfred Beit joined him in Kimberley, and Porgès formed the Compagnie Française des Mines de Diamants du Cap. Porgès returned to London after having made Wernher and Beit partners in the firm of Jules Porgès & Co. By 1884 Wernher returned to London and traded in diamond shares, while Beit remained in Kimberley to look after their interests. On Porgès' retirement in 1889, the firm was restructured and named Wernher, Beit & Co.
With the discovery in 1886 of gold on the Witwatersrand, the firm appointed Hermann Eckstein as their representative in Johannesburg, while Cecil Rhodes and Beit effectively amalgamated the Kimberley diamond mines by 1888 and enabled Wernher, Beit & Co. to acquire a controlling interest in De Beers Consolidated Mines. Wernher by now was managing over 70 South African companies from his London office, and developing a passion for collecting art. He was created a baronet in 1905, as well as being a member of the Order of the Crown of Prussia. Despite having a reputation for prudence in business, Wernher was swindled out of £64,000 in 1906 by Henri Lemoine, who claimed he could make synthetic diamonds.
Beset by failing health in 1911, Wernher merged the shareholdings of Wernher, Beit & Co. with those of Central Mining and Investment Corporation and Rand Mines Ltd. Besides his interest in art, Wernher funded an extension to the National Physical Laboratory. He also bequeathed £250,000 to establishing a university in Cape Town, and £100,000 to the Imperial College of Science and Technology in London.
At the time of his death in London, he was one of the richest men in the United Kingdom with a fortune of £12 million (then $60 million in face value, then about 20–30 times than in current purchasing power). This accumulation of wealth was due to his level-headedness and attention to detail. In contrast, Beit was shrewd but impulsive, leading to fiascos like the Jameson Raid.
Wernher kept his art collection at his London mansion, Bath House in Piccadilly, and at his country house Luton Hoo (occupied by Robert de Hoo in 1245). Much of it is now on display at Ranger's House in the London suburb of Greenwich. A large memorial to Wernher now flanks the entrance to the Royal School of Mines in London.
