Van Walbeeck is thought to have been born in Amsterdam in 1601 or 1602 and he might be the Jan van Walbeeck, son of the merchant Jacob van Walbeeck and of Weijntgen van Foreest, who was baptized on August 15, 1602, in Amsterdam. He studied at the University of Leiden before enlisting as navigator and cartographer on the ship De Amsterdam during the three-year circumnavigation of the world from 1623 to 1626 by the Nassau fleet led by Admiral Jacques l'Hermite and Vice Admiral Gheen Huygensz Schapenham. It is thought that the account of this voyage published by Hessel Gerritsz shortly after the expedition's return in 1626 was written and drawn by Van Walbeeck. In 1627, Van Walbeeck continued his mathematics and physics study in Leiden, but interrupted it again to join Laurens Reael's diplomatic mission to Denmark at the end of the year. Upon his return, he enlisted in a fleet that sailed to the Dutch East Indies. made by Van Walbeeck In 1629, back in the Netherlands, he changed employment from the Dutch East India Company to the Dutch West India Company. In April 1630, he arrived on the ship Neptunus in Pernambuco, after Hendrick Cornelisz Loncq had taken Olinda in February and Recife in March from the Portuguese. Van Walbeeck immediately was made a member of the Politieke Raad, the highest level of government in Dutch Brazil. Already in the same year, Loncq sent him and Maarten Valck to establish a Dutch base on the Chilean coast from which to explore Terra Australis. However, due to the colonial conflicts between the Dutch Republic and Portugal, the expedition did not get to its destination. Several more expeditions followed, until in 1632 Van Walbeeck was promoted to president of the Politieke Raad. In 1633, Van Walbeeck and the governor of Dutch Brazil, Dierick van Waerdenburgh, left for the Dutch Republic to meet with the WIC council. The WIC had lost its base in the Antilles when a Spanish fleet had destroyed its settlement on Sint Maartenin the summer of that year. The council now planned a base in Curaçao and Bonaire, Lesser Antilles under Spanish rule of Province of Venezuela, both for the salt pans, and as a strategic location off the South American mainland. The natural harbor of St Anna Bay on Curaçao was the perfect location for this. On April 6, 1634 they assigned Van Walbeeck to the task of taking it from the Spanish, who had colonized the island since the 1520s. On 4 May 1634, he departed from Holland with four ships, carrying 180 sailors and 250 soldiers, led by the French Huguenot mercenary Pierre Le Grand who had previously served the Dutch in Brazil. The small fleet arrived at Curaçao on July 6, but through adverse currents and winds could not enter the bay. On July 29, after being joined by a fifth ship and approaching from the north west, the fleet could enter the bay and captured the island from Spain with little resistance and without loss of life on either side. Van Walbeeck wrote in his diary, as transcribed by Johannes de Laet before it was lost, that the 32 Spanish and under 500 remaining local Arawaks inhabitants just withdrew to the West end of the island after poisoning their wells and burning their villages. On August 21 the Spanish commander, Lope Lopez de Morla, signed the surrender. The Dutch deported the Spaniards and most West Indians to the Venezuelan port of Coro, keeping about seventy-five of the latter as laborers. Thus, Van Walbeeck became the first director/governor of the Netherlands Antilles. The first task was to build a fortification at the natural harbor, renamed "Schottegat" by the Dutch, which pentagonal structure Fort Amsterdam was finished in 1635, following standard Dutch military engineering practice. During his three years as governor, the beginnings of the town of Willemstad were built next to the fort. In 1638, he and Le Grand were sent to Brazil, while Jacob Pietersz Tolck took over his position as governor although van Walbeeck remained political director of Curaçao for the next several years. He stayed in Brazil as a member of the Hoge Raad until 1642, after which he returned to Holland again to give advice on the forthcoming expedition under Hendrick Brouwer to establish a trading base in Chile. He went back to Brazil, being mentioned as elder of the Reformed Church there. In 1647 he left Brazil. Maybe he died in the Netherlands, as he lived in Amsterdam when his wife was buried there on 29 April 1649. Like Peter Stuyvesant, Van Walbeeck was one of the limited number of WIC employees with a university education. The company appears to have valued him at least as highly as Stuyvesant and it has been suggested that he missed being appointed director-general of the New Netherlands merely by not being in the Netherlands at the right time.
