Isaac Le Maire

Isaac Le Maire (c. 1558 – 20 September 1624) was a Dutch entrepreneur and investor who became one of the earliest major shareholders in the Dutch East India Company (VOC). He is best known for his prolonged conflict with the VOC, a struggle that ultimately contributed to the discovery of Cape Horn.

Isaac Le Maire was born in 1558 or 1559 in Antwerp. His father, Jacques le Maire, and his uncle Adam le Maire, were merchants from Tournai who became citizens of Antwerp in 1555. The Le Maire family traded with the Baltic port of Narva within a broader network of Tournai-origin merchant families, including the Van de Walle family. Isaac later became the brother-in-law of Jacques van de Walle, a pioneer in the trade with Russia and Arkhangelsk.

Isaac had four brothers, three of whom were merchants. By 1584 he was registered in Antwerp as a wealthy grocer. At the same time he served as captain of a company of the Antwerp schutterij. He rented the house known as the Bourgognien Schilt, but in 1585, following the Fall of Antwerp, he fled to the northern Netherlands.

In 1585 he settled in Amsterdam. He had earlier married Maria Jacobsdochter Walraven in Antwerp, and together they had twenty-two children. Archival baptismal records from Amsterdam confirm numerous children born to the couple. One of their surviving sons, Jacob le Maire, became known as a notable explorer. Another son, Maximiliaen le Maire, was appointed the first VOC opperhoofd at Dejima in 1641.

Initially, Isaac Le Maire was the largest individual shareholder of the VOC.

In 1592 his name appeared for the first time in Amsterdam records as a participant in one of the city's earliest documented marine insurance policies. In the following years he expanded his activities in European maritime trade. Although he was not initially among the wealthiest merchants, he was able to make substantial investments by securing warrant positions within his direct and extended family network.

Together with Peter van de Pulle and Dirck van Os he formed a company for trading with Russia. They shipped Baltic grain and timber to Spain, while ships carrying leather, wax, furs, and caviar from Arkhangelsk were often destined for Venice and Livorno. Their firm also traded in bills of exchange, engaged in chartering, and dealt in various forms of marine insurance. Between 1594 and 1598 he also played a major role in the fish trade between British ports and Spain.

After Cornelis de Houtman completed the first Dutch voyage to the Indies (1595–1597), Le Maire—like many other merchants—entered the Asian trade. In 1599 he and several partners in Amsterdam founded the Brabant Company, which sent two expeditions to the Indies. The company proved highly profitable, reportedly yielding returns of about 400 percent.
