As one of the most talked-about figures, Calouste Gulbenkian has built a significant fortune. In this article, we dive deep into the assets and career highlights.

What Was Calouste Gulbenkian's Net Worth?

Gulbenkian is considered to be the first person to exploit oil in Iraq. Notably, he was integral in making Middle Eastern petroleum reserves accessible to the West. Calouste was also renowned for his prolific philanthropy, which included the establishment of hospitals, schools, and churches.

A year after graduating from King's College, Gulbenkian traveled to Baku, Azerbaijan, to advance his understanding of the oil industry. From his studies, he penned an article for the literary and cultural affairs magazine Revue des deux Mondes. Following this, Calouste was tasked by Ottoman Minister of Finance Hagop Pasha with preparing an oil survey of Mesopotamia. Ultimately, his survey convinced Pasha that Mesopotamia housed vast oil deposits; Pasha consequently obtained tracts of land and established the Ottoman oil industry. Soon, Gulbenkian began his own oil business.

Calouste Gulbenkian was a British-Armenian oil magnate and philanthropist who had a net worth equal to $8.6 billion at the peak of his life, after adjusting for inflation. Without adjusting for inflation, Calouste Gulbenkian's fortune was estimated to be worth $200 – $800 million in the early 1950s.

Among his other oil industry milestones, Gulbenkian was the catalyst for the creation of the Turkish Petroleum Company, a consortium of the biggest oil companies in Europe that aimed to obtain oil development rights in Mesopotamia. Following the dissolution of the Ottoman Empire, the Turkish Petroleum Company was given exclusive rights for Mesopotamian oil exploration. In 1929, the company was renamed the Iraq Petroleum Company. Later, in 1938, Calouste incorporated a company from Panama to hold his oil industry assets; this resulted in the Partex Oil and Gas Corporation.

In 1896, Gulbenkian and his family were forced to flee the Ottoman Empire due to the genocide of Armenians. Ending up in Egypt, Calouste met oil magnate and philanthropist Alexander Mantashev, who introduced him to a number of influential contacts based in Cairo. Gulbenkian soon moved to London and became a naturalized British citizen in 1902.

Calouste Gulbenkian was born on March 23, 1869, in Constantinople in the Ottoman Empire. His family is believed to be descended from the Armenian noble family the Rshtunis. Gulbenkian's father, Sarkis, was an Armenian importer and exporter of oil who owned oil fields in the Caucasus. As a youth, Calouste went to the local school Aramyan-Uncuyan. He subsequently went to the French school Lycée Saint-Joseph and then attended Robert College. In 1884, Gulbenkian dropped his studies to move to Marseille, where he sought to perfect his French-speaking skills. He went on to attend King's College London to study petroleum engineering and graduated at the age of 18.

Gulbenkian made one of his first major moves in the oil industry in 1907, when he aided in the merger of Royal Dutch Petroleum Company with Shell Transport and Trading Company. He subsequently became a significant shareholder in the newly created Royal Dutch Shell. Due to his policy of keeping 5% of the shares of this and other oil companies he formed, Calouste was dubbed "Mr. Five Per Cent."

Ultimately, Calouste Gulbenkian's financial journey is a testament to their success.
