Marcus Samuel Sr. Ran a seashell trading business in Victorian London — importing decorative shells from the Far East to sell to collectors and craftspeople. His son, Marcus Samuel Jr. inherited the business and identified an opportunity in 1892 that had nothing to do with seashells: the Suez Canal Company had prohibited petroleum tankers due to fire risk from vapor accumulation in conventional vessels. Samuel commissioned the SS Murex, a ship specifically designed to carry bulk liquid petroleum safely through the canal, and negotiated Rothschild oil supply from Baku. The first voyage of the SS Murex in 1892 — 4,000 tons of Russian kerosene to Japan — established the trading model that Shell still operates.
Shell Transport and Trading Company was formally founded in 1897. The merger with Royal Dutch Petroleum in 1907 combined Marcus Samuel's British trading and transport infrastructure with Henri Deterding's Dutch production operations in the East Indies — creating the Royal Dutch Shell Group that remained the formal corporate structure until the 2005 unification into a single Anglo-Dutch entity.
The Russian nationalization of 1917 stripped Shell of its Baku oil assets without compensation. Mexican nationalization in 1938 removed another major producing region. The pattern of operating in high-risk jurisdictions and losing assets to political change is not unique to Shell — it defines the history of every oil supermajor — but Shell's response was always to replace lost capacity elsewhere rather than reduce geographic risk. The BG Group acquisition for approximately $53 billion in 2016 was the most recent major rebuilding move, substantially expanding the LNG business that now represents Shell's most strategically differentiated capability.
