Exactly 100 years ago today, the smell of sulfur hovered in the air at Masjid-i-Suleiman. That was a good sign for an experienced oil hand like Reynolds. At 4 in the morning, the drill reached 1,180 feet below the desert and struck oil. A huge gusher shot 75 feet into the air.

The site was so remote that it took five days before D'Arcy got word by telegram in England. "If this is true," he replied, "all our troubles are over." It was indeed true, and more wells hit oil elsewhere in Persia, including a huge one in September.

D'Arcy and Burmah reorganized their holdings in 1909 as the Anglo-Persian Oil Co. (which became the Anglo-Iranian Oil Co. in 1935, British Petroleum in 1954 and BP in 2000.) Its initial public offering of stock shares sold out in 30 minutes in London. People stood five deep around the tellers' cages to buy shares in Glasgow. The race for oil accelerated throughout the Middle East.
