A man named William found oil. 
A man named William worked in many lands. 

William Knox D'Arcy was a businessman from England. 
Later, D'Arcy wanted to find oil in Persia. Persia is a country in the Middle East. In 1901, he signed a deal to search for oil there. This deal was called the D'Arcy Concession.
D'Arcy spent a lot of money on his search. He spent many thousands of pounds. By 1908, he had almost run out of money. He told his team to stop working and come home.
But a lucky thing happened. Just after he sent the message, his team found oil! This happened in May 1908. This find helped him start a new company. It was called the Anglo-Persian Oil Company. Today, we know this company as BP. D'Arcy was a director of this new company. He lived a grand life until he died in 1917.
William Knox D'Arcy was a very successful businessman. He helped start the oil industry in Persia. 
Before he found oil, D'Arcy worked in mining. He lived in Rockhampton, Queensland, in Australia. In 1882, he joined a group to open a mine. This mine was on Ironstone Mountain in Queensland. Later, the place was renamed Mount Morgan. The mine had a huge amount of gold. 
In 1900, D'Arcy decided to look for oil in Persia. Persia is a country in the Middle East. He signed a big deal in May 1901. This was called the D'Arcy Concession. It gave him the right to look for oil and gas. He had to pay the Iranian government for this. The government received 16% of the company's yearly profits. This agreement lasted until 1952.
Finding oil was a very hard job. D'Arcy spent a huge amount of money on drilling. By 1908, he had almost run out of money. He was even overdrawn at Lloyds Bank. He sent a telegram to his team. He told them to stop work and come home. 
This lucky find changed everything for D'Arcy. In 1909, he became a director of the new Anglo-Persian Oil Company. By 1911, the company had a pipeline. This pipeline moved oil to a refinery at Abadan. D'Arcy lived a grand life in England. He owned a large mansion called Stanmore Hall. He died in 1917 at the age of 67. 
William Knox D'Arcy was a British and Australian businessman. He was a primary founder of the oil and petrochemical industry in Persia. This work helped create the modern energy landscape. D'Arcy founded the Anglo-Persian Oil Company in 1909. This organization eventually became the global company known as BP. His life involved moving between different continents and industries. He transitioned from gold mining to petroleum exploration.
D'Arcy was born in Newton Abbot, England, in 1849. His father, William Francis D'Arcy, was a solicitor. In 1866, the family moved to Australia due to his father's bankruptcy. They settled in Rockhampton, Queensland. D'Arcy studied law and joined his father's business. He eventually began speculating in land. He married Elena Birkbeck in 1872. Elena was the daughter of a mining engineer from the United States. Her family had roots in the English Quaker community.
Before his work in oil, D'Arcy found success in mining. In 1882, he became a partner in a mining syndicate. This group opened a mine on Ironstone Mountain in Queensland. The site was later renamed Mount Morgan. In 1886, the group became the Mount Morgan Gold Mining Company. D'Arcy served as a director and the largest shareholder. He held 125,000 shares in his name. He held another 233,000 shares in trust. At one point, these shares were worth more than £6 million. The company also operated a gold mine in New Zealand.

In 1900, D'Arcy began looking for oil and minerals in Persia. He never visited the country himself. In May 1901, he secured the D'Arcy Concession. He negotiated this deal with Mozaffar al-Din Shah Qajar. D'Arcy paid £20,000 for a sixty-year right to explore. This concession covered most of Persia, except for five northern provinces. D'Arcy could search for oil, natural gas, asphalt, and ozokerite. In exchange, the Iranian government received 16% of the company's annual profits. This profit-sharing agreement lasted until 1952.

The process of finding oil was difficult and expensive. A drilling team led by George B. Reynolds started work in 1902. By 1904, D'Arcy had spent £160,000. He was also overdrawn at Lloyds Bank by £177,000. In 1905, he formed the Concession Syndicate. The Burmah Oil Company Ltd. became a major investor. Operations moved to the Shardin region in 1906. Drilling continued in southern Persia until 1907. Then, the search moved to Masjed Soleyman. The team worked at a site called Maydon-e-Naftune.

By April 1908, the venture was close to failing. D'Arcy was nearly bankrupt. He decided to abandon the exploration in Iran. In early May 1908, he sent a telegram to Reynolds. The message ordered the staff to be dismissed. It told them to dismantle everything worth transporting. Reynolds delayed following these orders. On May 26, 1908, the team struck oil by chance. This discovery changed the future of the company. In 1909, D'Arcy became a director of the Anglo-Persian Oil Company.

By 1911, the company built a pipeline. This line ran from the oil find to a refinery at Abadan. D'Arcy also served as chairman of the Mount Morgan company in London. In his later years, he lived at Stanmore Hall in Middlesex. He commissioned famous tapestries called 'The Quest of the Holy Grail'. He also collected various paintings. D'Arcy died on May 1, 1917, at the age of 67. In 2012, he was added to the Queensland Business Leaders Hall of Fame. His life connected the mining traditions of Australia to the global oil industry.
